Python 3 Support¶
Flask and all of its dependencies support Python 3 so you can in theory start working on it already. There are however a few things you should be aware of before you start using Python 3 for your next project.
Requirements¶
If you want to use Flask with Python 3 you will need to use Python 3.3 or higher. 3.2 and older are not supported.
In addition to that you need to use the latest and greatest versions of itsdangerous, Jinja2 and Werkzeug.
API Stability¶
Some of the decisions made in regards to unicode and byte untilization on Python 3 make it hard to write low level code. This mainly affects WSGI middlewares and interacting with the WSGI provided information. Werkzeug wraps all that information in high-level helpers but some of those were specifically added for the Python 3 support and are quite new.
A lot of the documentation out there on using WSGI leaves out those details as it was written before WSGI was updated to Python 3. While the API for Werkzeug and Flask on Python 2.x should not change much we cannot guarantee that this won’t happen on Python 3.
Few Users¶
Python 3 currently has less than 1% of the users of Python 2 going by PyPI download stats. As a result many of the problems you will encounter are probably hard to search for on the internet if they are Python 3 specific.
Small Ecosystem¶
The majority of the Flask extensions, all of the documentation and the vast majority of the PyPI provided libraries do not support Python 3 yet. Even if you start your project with knowing that all you will need is supported by Python 3 you don’t know what happens six months from now. If you are adventurous you can start porting libraries on your own, but that is nothing for the faint of heart.
Recommendations¶
Unless you are already familiar with the differences in the versions we recommend sticking to current versions of Python until the ecosystem caught up.
The majority of the upgrade pain is in the lower-level libararies like Flask and Werkzeug and not in the actual high-level application code. For instance all of the Flask examples that are in the Flask repository work out of the box on both 2.x and 3.x and did not require a single line of code changed.

This time:
October 29, 2009
I want more for you and I
the charms fall like autumn leaves do
catch them if you can
-before they touch the ground and are just another leaf among them all
Touch the ground!
It will cast you-
the way the ground feels
to your hand
is all the sensation that life may bring to you
the commotion will bring-up a cloud of dust
which will settle before the wind does catch you
for you are the solid earth- fundament
secured by bed-rock
We will abate erosion on your grounds with gentle upkeep
I will tend to you a garden for our needs
-we can build channels for the streams
the running water-fall
to enter tributaries
that leave this hillside mountain behind
You and I will see something in evocations
reflecting the seasons
they move over you and I
we can take the roads out
to go,
see were the people are off to
who passed on, who’s new -
what is wrong out there
we can draw attention to
As I alluded to before,
a new age will be built
on the grounds that you touch
you will bring about life there
and we will bring about
the infrastructure necessary-
The principles and point up to something
more than just this simple notion
because when we die
like a vegetable we go in back into the ground that
we so took from all our lives-
back into the earth we go
and again we will bring about it, life
not yours, not mine-
-so, this life, hand in hand with the next one:
is in principle unlike that which returns soil to the ground
we are frozen in flight
we are lost to what storms the world forever-
So storm here!
we can design a world and life that cannot wash away with time
nothing can bring hell here,
no breaking the world unto a night-mare

Cheshire3 Objects: Server |
A Server object is a collection point for other objects, and an initial entry point into the system for requests from a ProtocolHandler. A server might know about several Databases, RecordStores and so forth, but its main function is to check whether the request should be accepted or not and create an environment in which the request can be processed. It will likely have access to a UserStore database which maintains authentication and authorisation information. The exact nature of this information is not defined, allowing many possible backend implementations. Servers are the top level of configuration for the system and hence their constructor requires the path to a local XML configuration file, however from then on configuration information may be retrieved from other locations such as a remote datastore to enable distributed environments to maintain synchronicity.
Note: the Server API is not well tested and is currently under review

8.7. The Defects section¶
The $defects
section specifies defects by:
- defect type:
- vacancy
- interstitial
- substitution or antisite
- defect coordinates
- defect element symbol
- Note that if an
elementmap
subsection is given in The Structure section, then the mapped designationsX1
,X2
, and so on can be given instead of an element symbol.
- Note that if an
ATTENTION:
- Elements in the initial structure, given in The Structure section, will appear in order as entered, by posfile keyword or through the coordinates and/or elementmap subsections.
- However, once a defect is formed, structures are RESORTED by element ELECTRONEGATIVITY. Therefore, if you are using substitutional defects or non-self-interstitials, you may find that later element-specific keywords (mast_setmagmom, LDAUU, LDAUJ) may be OUT OF ORDER FOR YOUR DEFECTED STRUCTURE.
- Please check your files carefully! You may want a separate input file for each chemical system (possibly created through looping (see Input File) in order to synchronize the elements and element-specific keywords.
The coord_type
keyword specifies fractional or cartesian coordinates for the defects.
The threshold
keyword specifies the absolute threshold for finding the defect coordinate, since relaxation of the perfect structure may result in changed coordinates.
Example $defects
section:
$defects
coord_type fractional
threshold 1e-4
vacancy 0 0 0 Mg
vacancy 0.5 0.5 0.5 Mg
interstitial 0.25 0.25 0 Mg
interstitial 0.25 0.75 0 Mg
$end
The above section specifies 4 point defects (2 vacancies and 2 interstitials) to be applied separately and independently to the structure. When combined with the correct recipe in The Recipe section, four separate ingredients, each containing one of the defects above, will be created.
Multiple point defects can be also grouped together as a combined defect within a <defect label>
subsection such as:
$defects
coord_type fractional
threshold 1e-4
begin doublevac
vacancy 0.0 0.0 0.0 Mg
vacancy 0.5 0.5 0.5 Mg
end
interstitial 0.25 0.25 0 Mg
interstitial 0.25 0.75 0 Mg
$end
In this case, there will be three separate defect ingredients: one ingredient with two vacancies together (where the defect group is labeled doublevac
), one interstitial, and another interstitial.
8.7.1. Charges for defects¶
Charges can be specified as charge=0,10
, where a comma denotes the lower and upper ranges for the charges.
Let’s say we want a Mg vacancy with charges from 0 to 3 (0, 1, 2, and 3):
vacancy 0 0 0 Mg charge=0,3
Let’s say we want a dual Mg vacancy with a charge from 0 to 3 and labeled as Vac@Mg-Vac@Mg:
begin Vac@Mg-Vac@Mg
vacancy 0.0 0.0 0.0 Mg
vacancy 0.5 0.5 0.5 Mg
charge=0,3
end
For a single defect, charges and labels can be given at the same time:
Let’s say we have a Mg vacancy with charges between 0 and 3, and we wish to label it as Vac@Mg:
vacancy 0.0 0.0 0.0 Mg charge=0,3 label=Vac@Mg
The charge and label keywords are interchangeable, i.e. we could also have typed:
vacancy 0 0 0 Mg label=Vac@Mg charge=0,3
If you use charges in the defects section like this, then you must use a tagged defect_<N>_<Q>
type recipe in The Recipe section.
8.7.2. Phonons for defects¶
Phonon calculations are described by a phonon center site coordinate and a phonon center radius (uses pymatgen’s find_in_coord_list_pbc method for radial tolerance). Atoms within the sphere specified by these two values will be included in phonon calculations.
For VASP, this inclusion takes the form of selective dynamics T T T for the atoms within the sphere, and F F F otherwise, in a phonon calculation (IBRION = 5, 6, 7, 8)
If the phonon center radius is 0, only the atom found at the phonon center site point will be considered.
To use phonons in the defects section, use the subsection keyword phonon
followed by:
- A label for the phonon
- The fractional coordinates for the phonon center site
- A float value for the phonon center radius
- An optional float value for the tolerance-matching threshold for matching the phonon center site (if this last value is not specified, 0.1 is used). Only used if atom indexing is not used.
If atom indexing is used, only the phonon center site and phonon center radius are used, with an additional 0.0001 matching tolerance.
Multiple separate phonon calculations may be obtained for each defect, for example:
begin int1
interstitial 0.25 0.25 0.25 X2
phonon host3 0.3 0.3 0.4 0.25 0.01
phonon solute 0.1 0.1 0.2 0.05
end
In the example above, host3 is the label for the phonon calculation where (0.3, 0.3, 0.4) is the coordinate for the phonon center site, and 0.25 is the fractional radius for the sphere inside which to consider atoms for the phonon calculation. Points within 0.01 of fractional coordinates will be considered for matching the phonon center site, if atom indexing is not used.
In the example above, solute is the label for the phonon calculation bounded within a 0.05 fractional radius centered at (0.1, 0.1, 0.2) in fractional coordinates. As no threshold value was given, points within 0.1 (default) of fractional coordinates will be considered for matching the phonon center site, if atom indexing is not used.
The recipe template file for phonons may include either the explicit phonon labels and other labels, or <S>, <N>, <Q>, <P>. See The Recipe section.
Because phonons are cycled with the defects, a new parent loop must be provided for the phonons, for example:
{begin}
defect_<N>_<Q>_stat (static)
phonon_<N>_<Q>_<P> (phonon)
phonon_<N>_<Q>_<P>_parse (phononparse)
{end}

Widow of ex-KGB agent plans legal action on UK's Russia report
LONDON (Reuters) - The widow of a Russian dissident murdered in London plans to challenge a decision by Prime Minister Boris Johnson’s government not to publish a report on alleged Russian meddling in Britain, a lawyer representing the widow said.
Marina Litvinenko, whose husband Alexander, a former KGB agent, was murdered with a radioactive isotope in 2006, sent Johnson a letter on Wednesday saying she planned to take legal action, lawyer Elena Tsirlina said.
“A response is now expected by 4 p.m. on 19 November 2019,” Tsirlina said in a statement, adding Litvinenko would only proceed if she secures funding via the CrowdJustice fund-raising site by that date.
Litvinenko’s page on the site said there was “a profound public interest in the information being disclosed to the public, so they are fully informed of the extent of Russian interference in British politics before they go to the polls on 12 December 2019.”
The report by parliament’s Intelligence and Security Committee (ISC) has been cleared by Britain’s security services but it has not yet been approved for publication by Johnson’s office, meaning it will not be released before the election since parliament has shut to allow for campaigning.
Britain has accused Russia of meddling and trying to interfere in elections in the West, which Moscow denies.
The ISC was examining allegations of Russian activity aimed at the United Kingdom, including in the 2016 referendum on EU membership, when Johnson was a leading Leave campaigner.
U.S. intelligence agencies have accused Russia of interfering in the 2016 U.S. presidential election, which was won by Republican Donald Trump.
Hillary Clinton, who ran as the Democratic Party’s candidate in 2016, said earlier this week the failure to publish the report was “inexplicable and shameful.”
According to a British public inquiry in 2016, two Russians carried out Litvinenko’s murder, one of them a former KGB bodyguard who became a Russian lawmaker, in an operation probably ordered by Russian President Vladimir Putin.
Moscow has denied the allegations.


Watch: Deontay Wilder Sets Up Tyson Fury Rematch With Another Knockout Shot
by Aonghus Ó MaicínThe rematch everybody wants is on. Deontay Wilder set up a highly-anticipated rematch with Tyson Fury last night in Las Vegas after dropping Luis Ortiz in the seventh round of their heavyweight contest.
The rematch has now been pencilled for February, last night's fight being Wilder's last appearance before returning to the ring for his second bout with the Gypsy King.
Speaking to Sky Sports after the bout, the American confirmed Fury was the next man on his radar, though he also revealed he had his eyes on the winner of the other major heavyweight fight in the world of boxing happening early next month.
Tyson Fury is definitely next and after that I want a unification bout with whoever the winner is [between Anthony Joshua and Andy Ruiz Jr]. Right now, we're ready for Tyson Fury. Hopefully he's ready for me.
The Bronze Bomber delivered on his reputation as the hardest hitter in boxing at the MGM Grand Garden Arena, stretching his unbeaten record to 42 fights, all but two of those being stopped early. Fury, however, famously recovered from one of Wilder's devastating punches last December in a fight that resulted in a split-decision.
Next February's bout is expected to be the biggest heavyweight bout in recent memory given the clash of styles on show. While Wilder's power is peerless among the current stable of heavyweight fighters, so, too, is Fury's boxing intellect. All in all, both men are expected to earn more from next spring's fights than any of their previous bouts.

| Defined in: | activemodel/lib/active_model/dirty.rb |
Overview
Provides a way to track changes in your object in the same way as Active Record does.
The requirements for implementing Dirty
are:
-
include ActiveModel::Dirty
in your object. -
Call
define_attribute_methods
passing each method you want to track. -
Call
attr_name_will_change!
before each change to the tracked attribute. -
Call #changes_applied after the changes are persisted.
-
Call #clear_changes_information when you want to reset the changes information.
-
Call #restore_attributes when you want to restore previous data.
A minimal implementation could be:
class Person
include ActiveModel::Dirty
define_attribute_methods :name
def initialize(name)
@name = name
end
def name
@name
end
def name=(val)
name_will_change! unless val == @name
@name = val
end
def save
# do persistence work
changes_applied
end
def reload!
# get the values from the persistence layer
clear_changes_information
end
def rollback!
restore_attributes
end
end
A newly instantiated Person
object is unchanged:
person = Person.new("Uncle Bob")
person.changed? # => false
Change the name:
person.name = 'Bob'
person.changed? # => true
person.name_changed? # => true
person.name_changed?(from: "Uncle Bob", to: "Bob") # => true
person.name_was # => "Uncle Bob"
person.name_change # => ["Uncle Bob", "Bob"]
person.name = 'Bill'
person.name_change # => ["Uncle Bob", "Bill"]
Save the changes:
person.save
person.changed? # => false
person.name_changed? # => false
Reset the changes:
person.previous_changes # => {"name" => ["Uncle Bob", "Bill"]}
person.reload!
person.previous_changes # => {}
Rollback the changes:
person.name = "Uncle Bob"
person.rollback!
person.name # => "Bill"
person.name_changed? # => false
Assigning the same value leaves the attribute unchanged:
person.name = 'Bill'
person.name_changed? # => false
person.name_change # => nil
Which attributes have changed?
person.name = 'Bob'
person.changed # => ["name"]
person.changes # => {"name" => ["Bill", "Bob"]}
If an attribute is modified in-place then make use of [attribute_name]_will_change! to mark that the attribute is changing. Otherwise Active Model can't track changes to in-place attributes. Note that Active Record can detect in-place modifications automatically. You do not need to call [attribute_name]_will_change! on Active Record models.
person.name_will_change!
person.name_change # => ["Bill", "Bill"]
person.name << 'y'
person.name_change # => ["Bill", "Billy"]

Now, the details if you want them.
Cashner had an MRI on Tuesday that confirmed the aggravation of his rotator cuff injury. MLB teams are really good at coming up with vague terms to describe injuries. Aggravation could mean anything from a minor sun burn to an arm completely falling off. The Cubs have not set a date for his return so I'm guessing it's somewhere between those two levels of severity. Other sources are saying July, but we'll see.
According to Jim Hendry, Tyler Colvin "...put himself in this spot". He's been optioned to Iowa after hitting .113 in 28 games. The Cubs are looking for the Colvin that showed up last year and hit 20 home runs and had 56 RBI.
The mighty Tony Campana made his major league debut last night vs. the Reds. After getting his three-sizes-too-big jersey from the Cubs equipment staff, the Cincinatti area native got to impress his family and friends with a pinch run scored, his first hit and an RBI. Campana is listed a 5' 8" 165 lbs, but looked like a third grader standing next to 6' 3" Joey Votto at first. Campana has been hitting .342 this year in Iowa and had a season average of .319 last year with Daytona. Don't expect any home runs to right from this lefty. Campana has never hit one in his professional career. Do expect pinch runs and stolen bases. He's fast. He had 66 steals in 2009. The top base stealer for the Cubs so far is Starlin Castro with 4. Tony already had 8 with Iowa.
Marcos Mateo has been streaky. He left with a 5.74 ERA in 20 appearances. Hendry has determined that Maine will be a better option in the bullpen based on his performance with the Cubs last year. Maine adds another lefty to the pen bringing the total to four now that James Russell has returned to his regular job.
CONGRATULATIONS DOUG DAVIS. After his first start with the Cubs on Saturday, Davis' wife went in to labor and gave birth to their daughter on Sunday. Davis is scheduled to start Sunday at Fenway.

Hi All,
I'm new to the world of 'OpenEnergyMonitor' and am amazed on the knowledge and enthusiasm that can be found throughout this forum. A short introduction: I myself am 46 years and live in the Netherlands. I work with unix/linux systems in the role of sysadmin but am no programmer. I'm also no electrical engineer and cannot read the schematics found around here. So soldering together my own set would not be such a great idea ;). As such the pre-assembled/build components found here in the shop would give me the perfect possibilities to put together a nice setup that should get me started. Now for measuring our power usage the bundle with the EmonTx with CT clips & RaspPI set should do the trick. I would however like to get the picture complete for our family including GAS (covering most of our utility bill) and water. Now this is the part where i'm lost a bit on the possibilities.
My GAS & Water meter are both from the company Itron and are compatible with the Cyble sensor (v2). Now from all the reading i understand that with the EmonTx v3.x you must use the pulse count screw terminal to be able to do 'something' with pulse counting.
So here are some questions i have;
Here ( https://www.itron.com/PublishedContent/Cyble%20Sensor%20EN%2003-14_Brochure.pdf ) are some more details on the Cyble sensor. On the market i can find different types of this sensor (2 wire version / 5 wire version) and a factory set so called 'K' factor (explained in the brochure). Now i know these are quite expensive but as mentioned i'm really not the guy to get my own soldering gun ;)
1st. Would this Cyble sensor be compatible to be used directly with the EmonTx v3.4 by connecting it to the ' pulse-counting screw terminal'. And if so which one, the 2 or 5 wire version and what ' K' factor and how to connect.
2nd. The EmonTx v3.4 (as i understand it) only has room to connect one pulse counter to the pulse-counting screw terminal. So if i would want to collect data from two different (Gas & Water) Cyble sensors i would also need two EmonTx v3.4 sensor nodes?. Or could the RaspberryPi be of some use here.
Any guidance is much appreciated.
Thanks & Kind regards
Patrick
Re: Cyble sensor compatibility EmonTx v3.4 (pulse counting)
I do not know enough about the Raspberry Pi to say whether that would be better, so I will only talk about the emonTx.
Your Cyble sensor requires a meter with the correct "Cyble Target". Your meters have that.
The Cyble sensor has an internal battery with a life of 12 years. Is this a concern? After 12 years (or maybe more, possibly less), you will need to replace the entire sensor.
I think you do not need the extra information that the 5-wire sensor gives you (direction of flow, both HF & LF outputs and cable cut detection), therefore the 2-wire version with K=1 is equivalent to the HF output of the 5-wire version.
The value of K determines the smallest quantity that you know about. With K=1, you have one pulse per revolution of the target. The printing on the meter face should say what that is in m3 (I cannot read that in the photograph). If it does not, you will need to count the number revolutions for one digit on the register.
I cannot think of an easy way for you to use two of these with one emonTx V3.4, so I think you will need two emonTx's. You connect the brown & white wires (either way round) to "IRQ1/Dig3" and "GND".
You will need to use a sketch that uses interrupts, and I think there is not yet one for the emonTx V3.4, therefore it will be necessary to convert the V3.2 version. This is not a major problem.
Re: Cyble sensor compatibility EmonTx v3.4 (pulse counting)
Hi Robert,
Thanks for your clear explanation, exactly what i was hoping to hear. I think i have everything now clear for myself and am going to proceed with building my set.
Thanks again.

Re: Cyble sensor compatibility EmonTx v3.4 (pulse counting)
If a utility meter provides an optical output, the activity can be captured using a simple LDR-based sensor. This can be polled every mains cycle (or every few milliseconds) to find the LED's state. This approach can use any of the IO pins.
On the emonTx V3, IO ports 5 and 19 are available at the 6-way terminal block in addition to digital 2 or 3 which supports interrupts.
Re: Cyble sensor compatibility EmonTx v3.4 (pulse counting)
The Cyble detector appears to use a 'metal detector' technique to determine the passing of the flag on the "fast" indicator, and the gas meter certainly does not have an optical pulse output—rather a reflective spot on the "first drum". To use that would require a LED illuminator, a detector and a means of mounting both that would also exclude ambient light, and as Patrick isn't a constructor, it's a non-starter. So he's better to stay with a proven device that doesn't require development beyond converting a sketch.
Re: Cyble sensor compatibility EmonTx v3.4 (pulse counting)
OK, Robert, I'm not familiar with the Cyble detector. I was simply picking up on the comment that:
... with the EmonTx v3.x you must use the pulse count screw terminal to be able to do 'something' with pulse counting.
If the meter provides an optical output, it is possible to use any of the IO ports for this purpose.
Re: Cyble sensor compatibility EmonTx v3.4 (pulse counting)
Hi,
Thanks for all the info provided. I just placed my order and hope i will get things going. Looking forward to playing around with it. In the mean time i'm learning every day here. This community is amazing.
Could well be i'll be posting some more questions in the near future when running into issues. But that's part of the fun. ;)
Thanks again all.
Kind regards
Patrick
Re: Cyble sensor compatibility EmonTx v3.4 (pulse counting)
"If the meter provides an optical output, it is possible to use any of the IO ports for this purpose."
It doesn't. They are gas and water meters and so do not have access to an electrical supply. The data sheet notes: "the fast duration of the pulse does not allow to connect electro-mechanical relays". From that I deduce that the pulse is less than a few hundred milliseconds wide, but they do not disclose anything else about it. It may well be wider than 20 ms and thus could be polled once per mains cycle by a standard input, but we cannot take that for granted and I think the only safe way is to use the interrupt input.
Re: Cyble sensor compatibility EmonTx v3.4 (pulse counting)
Did you get this to work ?
Have a watermeter with Cyble Sensor, so if it works for you i will go the same way.
Re: Cyble sensor compatibility EmonTx v3.4 (pulse counting)
Hi Larsjo,
That's a coincidence, just finished updating the emontx with latest FW (including pulse counting), going to try the cyble sensor this weekend, will for sure let you know the outcome. Furthermore i thought i had the itron cyble sensor compatible gas meter but was mistaking in that, so ordered a reed switch from flukso for the gas meter.
Kind regards
Patrick
Re: Cyble sensor compatibility EmonTx v3.4 (pulse counting)
Hi All,
A short update on the progress on my attempts to get water & gas pulse monitoring to work.
For each of the pulse generating sensors i use a eMonTX v3.4. So i have two eMonTX v3.4 units measuring a total of 7 CT sensors.
Started with connecting the Flukso sensor to the screw terminal pins 3 & 4. (on the TX using default v1.6 sketch). This seemed a somewhat frustrating process as i could not get any stable reading. Serial connected the emonTX to see what was detected. When connected at power-on the serial console showed weird counters.
When putting a small magnet on the sensor the pulse count remained stable at the same value (so concluding the senor is working)
Connect the Cyble sensor to my other emonTX and this produced the exact same result (so large number of pulsecounts while nothing was happening). Test with a magnet failed because of the way the Cyble sensor works (hence, its generating a pulse on its own when a cycle of the meter is detected.)
So was wondering on how to proceed and started googling-around. I finally landed on the arduino tutorial pages. ( http://www.arduino.cc/en/tutorial/button ) Modified it slightly with some info found elsewhere and resulted in the following sketch.
This is basically exactly what i was hoping for, just to see if the pulses were detected correctly from both the Cyble sensor and Flukso sensor. It will light the emonTX LED whenever a pulse is detected. This worked perfectly on both the sensors, for the GAS meter whenever the last digit showed the number '7' the LED would turn on. For the cyble sensor on the water meter this also worked but could clearly distinguish it is working in another way ( hence the cyble sensor would produce a pulse for a shorter amount of time because of the way it works)
I'm thinking that if i can produce a '1' or a '0' on the console and make the LED go on and off upon detection of one cycle of the gas & water meter it can be used 'somehow' in a sketch to produce some meaningful info to pus to emoncms.
So i'm basically at the point on discovering on how to incorporate this in the emonTX discrete sampling sketch (as the currently available pulse counting in that sketch isn't working for me)
One of the things that still a question mark for me would be the working of the Flukso reed switch. (hence, if gas was used but stopped exactly when the last digit shows 7 on my meter the LED would remain on)'. As stated, i'm no programmer and having real difficulties in understanding the sketches, but taking small steps at the time.
Will update whenever something interesting evolves in my little home project. (and of course any help would be much appreciated)
Kind regards
Patrick
Re: Cyble sensor compatibility EmonTx v3.4 (pulse counting)
What you're seeing there is no doubt contact bounce. The standard pulse input and routine in the default sketch is not suitable (as you've found out) for mechanical switches. I solved this problem a long time ago - see about half way down this thread. [Beware, that sketch was for the emonTx V3.2]
Re: Cyble sensor compatibility EmonTx v3.4 (pulse counting)
Good to hear that the water reading is working.
?? why the 7 digit, is that where the magnet is ?
Any photo of the setup.
Re: Cyble sensor compatibility EmonTx v3.4 (pulse counting)
There's quite a lot of information here: http://openenergymonitor.org/emon/node/1732
Re: Cyble sensor compatibility EmonTx v3.4 (pulse counting)
Hi Larsjo
Yes indeed the last digit is triggering my (Flukso) reed switch whenever the display show a '7'. So thats the position of the dial where the magnet is best positioned for the reedswitch.
Robert pointed me into the right direction in regards to the software debouncing. Found out (after doing a lot searching on the web) there are different approaches to this. I tested out some of them. I modified my sketch accordingly and now am pretty happy with the result (although it needs some tweaking still as the Cyble sensor seems to generate a few false pulses) During all the testing i also discovered the emonhub is not receiving all of the transmissions from both of my emonTx's. So some work needs to be done there. (perhaps both emonTx's being so close together interfere with each others radiosignal?) But overall readings (both water with the Cyble sensor and Gas with the Flukso probe) are satisfying for me.
Now with the pulses coming in i'm able to do the math. For me the most important one are the costs. I know from within Emoncms you can get some cost calculations but i personally like the ' My Electric' way of showing usage. Unfortunately not possible to display costs by default. So as (not being a coder) hacked my way through the scripts and modified it to show the cost as well.
Kind regards
Patrick

Nice work. Will give it a try.


Kolkata tickled pink as India embrace day-night Test against Bangladesh
by ReutersIndia maybe the last major Test playing nation to embrace pink-ball cricket but they have left no stone unturned in promoting their first day-night Test which will begin in front of a sellout crowd at Kolkata's Eden Gardens on Friday.
The eastern Indian city is firmly in the grip of a pink fever and tickets for the first four days have already sold out.
City landmarks are being illuminated in pink to mark the occasion, and a ball-shaped pink blimp hovers over the 67,000-capacity stadium.
Bangladesh Prime Minister Sheikh Hasina will headline the list of dignitaries and army paratroopers will descend to hand over pink balls to India captain Virat Kohli and his counterpart Mominul Haque.
"I don't remember similar excitement in any Test in India in the last 20 years," cricket historian Boria Majumdar told Reuters.
"The closest is the 2001 India-Australia Test but there too it was only on day five," he said, referring to India's sensational victory after being asked to follow-on.
In the stands will be 'superfan' Sudhir Chaudhary, a permanent fixture in all India matches with his painted body and an India flag.
"I attend all India matches but this is very special," Chaudhary, almost unrecognisable without body paint, told Reuters while sipping lemon tea from a roadside vendor outside Eden Gardens.
"Eden Gardens has a rich history and this is another chapter."
The players are not immune to the fever either.
Kohli said the last time he felt a similar buzz at Eden Gardens was when India played arch-rivals Pakistan in a Twenty20 World Cup match in 2016.
"It's a landmark occasion and we're lucky to be the first Indian team playing a day-night Test," Kohli told reporters on the eve of the 12th day-night Test in the game's history.
"It can be a daunting, intimidating experience for a player... I'm expecting exciting cricket in the first hour because the energy level will be very high. I'm sure the fans would enjoy it."
Approximately 5000 Bangladeshi fans will cheer Mominul and his men as they seek to bounce back from defeat inside three days in the series opener in Indore.
"Test cricket needs to be more competitive. At the same time, if you want to bring crowd back into Test cricket, pink-ball is an excellent idea," Mominul said ahead of what would be Bangladesh's maiden day-night Test as well.


Tell us how you are feeling about your dream by linking
1) blue with either red or green OR
2) yellow with either red or green.
First choose whether the dream made you feel good, or not good
Next, choose if the dream was about your inner reality, or the outside world
For example blue and then green would be ‘It was a dream that made me feel good on the inside’.
For example yellow and then red would mean ‘The dream made me feel bad about my external world’.
Tell us how you are feeling generally in your daily life at the moment by linking
blue with either red or green and also yellow with either red or green?
First choose whether you generally feel good or not good
Next, choose whether your emotions centre on yoursef, or the outside world
For example blue and then red would be ‘inside I’m not feeling good’.
For example yellow and then green would mean ‘socially I’m feeling good’.

I have managed to get some work experience at Summit Lab.ltd as an intern.
Here I was a technical assistant, helping around the office with various

Why Programming?
To be frank, I have no idea.
Then I discovered how much I enjoy learning how stuff actually works. I wanted to know what
happens when you double click. I wanted to learn how some movement made by my wrist would
transfer to electrical pulses that would then make the cursor move on the screen.
I wanted to create, to help. I wanted to change my world.

As you keep scrolling down and checking out some of these poems thatb touches various aspects of life, you can gain some solutions to problem facing you through my poems for example dwelling on the poem why the blame, it touches the aspect whereby you shouldnt blame others for your failure or mistakes. Dont let me be a show spoiler even before you get to read it....enjoooyy friends.
WHY THE BLAME
Why the blame, when someone fails he put the blame on someone or on something but forgetting he or she is the reason
for any of his failures that kind of person is not ready to change his ways.
You all know there is a reason for all failures, why dont we stop blaming others adn mend your ways to feel better.

Listen to Confidence Man’s infectious new dance-pop single, ‘Does It Make You Feel Good?’
Get down
Confidence Man have returned with a new single, ‘Does It Make You Feel Good?’ – you can listen to it below.
Sharing the song, the band described the song as “dance pop that sounds like Donna Summer and Giorgio Moroder” and added: “feelings are in right now and we’ve got some for you. Watch out, ‘cause the dance floor is wet with tears. Open up, and let us travel the waterslide deep into your heart.”
The video accompanying the single was filmed in Berlin and shot by their long-term visual collaborators Schall and Schnabel. You can watch this below:
The band have also announced details of a tour next April and May including a gig at The Forum in London – their biggest UK gig to date. Tickets of the London and Manchester shows go on pre-sale on November 19. The remaining U.K. shows go on pre sale on November 20 and all tickets go on general sale at 10am November 22.
The full list of dates are below.
APRIL
16 – Hebden Bridge, Hebden Bridge Trades Club
17 – London, O2 Forum Kentish Town
19 – Utrecht, Tivoli Vrendenburg – Pandora
20 – Paris, Backstage By The Mill
22 – Bristol, SWX
23 – Manchester, O2 Ritz
25 – Dublin, Button Factory
26 – Nottingham, Rescue Rooms
27 – Newcastle upon Tyne, The Boiler Shop
28 – Glasgow, SWG3 (TV Studio)
29 – Edinburgh, Liquid Rooms
MAY
1 – Spain, Murcia, Murcia Festival
Speaking to NME last year, Confidence Man described their band as being “completely different.” They added: “It’s so different – we were all in indie-rock bands and psych-rock bands and stuff like that. What we wanted to do was create a band that was dance music, but a bit ramshackle in a way, because we’re all from guitar backgrounds – so it’s indie-rock people making dance-pop music. It’s a bit weird, I think that’s why it works.
 Things have turned out well because I think people can see the messiness of it, and see that in the live show as well. It’s kind of punk-y.”
