Would be nice to have functionality to compare target energy / gas information so you can compare actuals to target.

And/or: compare last year's data with this year so you can see if you need to pay more or less compared to last year

I adapted the program a little bit for my own usage but maybe other people can use this so I put it here.
These meter is wireless connected to a gasmeter Itron G4RF1e WL .
Below the adapted program en screenshot.
The graph is a little bit crowded because I added also tariff3 and 4 because of my solar panels and also the gasmeter.

Hi,
tried to install the plugin, but it does not work for me. To see what is wrong I tried to get a log file via

npm install
chmod +x logP1.js
./logP1.js

The console responses that logP1.js does not exist.

With vzlogger I am receiving data.

I checked the p1meterdata.js file there I found this line:
var currentUsage = returnRegExResult(data, /^1-0:1.7.0\((.*?)\*/m);
This is what I'm interested in:
1-0:1.7.0\((.*?)\*/m);

I'm not familar with js, how can I change the existing code from p1meterdata.js to get the value from this line:
1.8.0*255/ObisIdentifier:1-0:1.8.0*255 value=3661100.90

Currently I read the value this way from the log via logWatcher Plugin of Pimatic:
1-0:1.8.0\x2a255\x20value=(.+)

I update Pimatic with the GUI and run up multiples errors. One was that the peerDependencies in package.json was to low. I updated it to below and reinstall the plugging. Only then it was working. it seems that the plugin don't like pimatic 0.9...

"peerDependencies": {
"pimatic": ">=0.8.0 <1.0.0"

I remove sqlite3 with sudo rm -rf /home/pi/pimatic-app/node_modules/sqlite3
and then installed manualy in sudo su with sudo npm install sqlite3.

It was nevewracking but when it was a succes it feels like a triompf! :)

If you nead more logging let me know.

Hello,
I use your plugin with this setup:
{
"id": "smartmeter",
"class": "Smartmeterdevice",
"name": "Smartmeter Strom",
"serialport": "/dev/ttyAMA0",
"baudRate" : 9600,
"dataBits" : 7,
"parity" : "even",
"stopBits" : 1,
"flowControl" : true
},

My electric meter gives with cat /dev/ttyAMA0 following information:

/ISk5MT671-0001

1-0:0.0.0*255(331300-5033124)

1-0:1.8.1*255(033238.2842)

1-0:96.5.5*255(80)

0-0:96.1.255*255(39225479)
!

There is only the meter reading 1-0:1.8.1*255(033238.2842) what means 33238.2842 kWh interesting.

Now your plugin shows in my Pimatic installation no data.

Hope you can help me.

Best regards
Andre

Hello,

I am using the plugin and it works like a charm!

But i want to see my usage for the day and week.

I have a clean install with the smart meter connected to USB0 and i'm getting the data.

The config:

"devices": [
{
"id": "smartmeter",
"class": "Smartmeterdevice",
"name": "Smartmeter",
"serialport": "/dev/ttyUSB0",
"baudRate": 9600,
"dataBits": 7,
"parity": "even",
"stopBits": 1,
"flowControl": true
},

But the database is not logging any variable.

How can i let pimatic log those values?

Thank you

Hi All,

In p1meterdata.js I have this regex;
var gasTotalUsage = returnRegExResult(data, /^0-1:24\.2\.1\(\d+[SW]\)\((\d+\.\d+)\*m3\)/m);

As far I can test the regex is working: https://regex101.com/r/kY1pE6/1

The status of gas usage is saying "Unknown" , any suggestions were to look ? I think i'm missing something.

Hello,

I also want to read the data from the p1 port.

Who can give me a hint to solve this problem.
Thank you in advance.

Hi nice work on the plugin.
My meter uses a different baud rate, could you make the baud rate a config option aswel?

{
  "plugin": "smartmeter",
  "serialport": "/dev/ttyUSB0",
  "baudrate": 115200
}

EDIT my meter also uses 8N1 :(
maybe other options aswel so more people will be able to use it
baudRate: 115200,
dataBits: 7,
parity: 'even',
stopBits: 1,
flowControl: true,

Upon start/restart an initial readout of 0 is send.

Hai Saberone,

Today I connected a CH340 USD-Serial converter to my Raspberry Pi B. Using the command CU I see a lot of blanc spaces and in Pimatic all I get is 0 Watt etc. When I connect the convertor to my PC and using Putty I get readable data on my screen.

The smartmeter is a Kaifa MA105. The settings in the device settings are:
"id": "smartmeter",
"class": "Smartmeterdevice",
"name": "Smartmeter",
"serialport": "/dev/ttyUSB0",
"baudRate": 115200,
"dataBits": 8,
"parity": "none",
"stopBits": 1,
"flowControl": true

I don't know what I'm doing wrong. Your help is needed!

Regards,
David

I have an Itron smartmeter for Gas. It looks like it transfers its data to the my Landis+Gyr smartmeter for Electra (which is connected to Raspberry Pi with Pimatic). Electra readings are correctly populated, however I miss the gas readings. When checking the output I do see it appearing:

Next line from above looks like my gas reading:

Can you check or tell me how I can make sure that it is populated into the gasmeter2.gastotalusage attribute.

Some people have problems with serialport 2.0.6 on the older node version. While for others it works fine.

Could you create a separate branch for pimatic 0.9.x ? and publish both to npm. One for pimatic 0.8 and one for 0.9.

0.8 needs serialport 1.4.5:

"dependencies": {
    "serialport": "~1.4.5"
  },
