Add Mqtt functionalities

[nagydavid]

@solmoller Hejsa,

I added an Mqtt functionalities with home assistant auto discovery config. Therefor it became more smart home software agnostic.

I wrote in PERL the first time in my life, so there could be a way to write it more elegantly. I tried to implement without shell scripts but all PERL-MQTT libraries were a little bit confusing, and it just added extra complexity.

I hope it helps some people.

Output in Home Assistant as a device and its entities

Apart from this I have an issue.:

• after night when the solar inverter turns on again (during the night it is turning completely off, so assuming this is how it should work) the scripts does not update anymore, so I am interested did @solmoller it is a bug, or my settings are wrong.

[solmoller]

That is very interesting. I went via Pvoutput:

• platform: pvoutput system_id: xxx api_key: xxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
  • platform: template sensors: power_consumption: value_template: > {% set pc = state_attr('sensor.pvoutput', 'power_consumption') %} {{ '0' if pc == 'NaN' else pc }} friendly_name: 'Using' unit_of_measurement: 'Watt' energy_consumption: value_template: "{{ '{:.1f}'.format(state_attr('sensor.pvoutput', 'ene$ friendly_name: 'Used' unit_of_measurement: 'kWh' power_generation: value_template: > {% set pg = state_attr('sensor.pvoutput', 'power_generation') %} {{ '0' if pg == 'NaN' else pg }}

But you get more data out, and I already use MQTT intensely.

As for the potential bug, I don't have that problem, so it's probably your code. I'll try to find time to debug

Thanks for looking at it. I did it because I want to have as less cloud polling as possible :)

[sorentorp]

Great work! Lets get it merged :-)

[solmoller]

Great work! Lets get it merged :-)

Jeg har ikke haft tid til at teste, hvis I siger det virker skal jeg nok merge...

[solmoller]

Whoops, in english: I haven't had the time to test, and David has implied issues with the code - if all is well I'll gladly merge

[sorentorp]

@nagydavid and @solmoller I did some testing.

I dont use u/pw for my mqtt - and that seems to be mandatory with this implementation. And so does the model name.

pi@raspberrypi:~/eversolar-monitor $ perl eversolar.pl mqtt_inverter_model expects an argument at eversolar.ini line 51 mqtt_user expects an argument at eversolar.ini line 54 mqtt_password expects an argument at eversolar.ini line 55 2022-01-03 00:49:12: Severity 1, Configfile is: eversolar.ini

[sorentorp]

I just used default username + password and my modelnumber "TL3000".

I also had to run "sudo apt-get install mosquitto-clients"

[sorentorp]

[sorentorp]

also the loglevel should be adjusted.

My settings are

debug = 1 # Debug level , 0 = none, 1 is high priority, 3 is everything, 4 also output

[sorentorp]

And AC Current should be "A" - not "V"

elsif ( $_[0] eq "iac" ){ $config_data{'icon'} = "mdi:current-ac"; $config_data{'name'} = "AC Current"; $config_data{'unit_of_measurement'} = "V"; <------- $config_data{'device_class'} = "current";

[nagydavid]

@solmoller @sorentorp tak for din anmeldelse af PR. Jeg bor i Danmark, så jeg kan forstå lidt dansk :P. About the PR, I will update the spelling errors, and make sure that u/p will be requested if it has any value.

[solmoller]

Thanks, I'll test shortly. Maybe we should add instructions on how to setup HASS?

[sorentorp]

A MQTT Broker and Hass - https://www.home-assistant.io/docs/mqtt/broker/

[nagydavid]

If the Mosquito broker is set up, then the eversolar.pl will send discovery messages so there will be no need for additional templates sensors in hass. Only the mqtt discovery needs to be enabled in the eversolar.ini .

[solmoller]

Thanks, I figured it out

Brilliant!
