MQTT solar-assistant

Post by octy »

I have a inverter connected to Solar-Assistant and they released mqtt support ( https://solar-assistant.io/help/integration/mqtt )
Have sett it up as i think it works, but get the messages under.

Solved some of them, did not have Auto Discovery Prefix to homeassistant.

But the ones containing battery information did not get created:
total/battery_power/state
total/battery_state_of_charge/state
Inverter_1/battery_voltage/state
Inverter_1/battery_current/state

And the temperature sender from the inverter is reporting low battery, but does not have battery..

Any idea where/how i can edit and add the missing devices?

Battery information can/should be found in the device overview

Could you post the config/data MQTT object of your inverter? You can find this by using (for example) MQTT Explorer

Some of the battery sensors does not show in domoticz, and some of the sensors in the inverter randomly says its low on battery.

Dear Octy,

I just installed SolarAssistant connected to my 3 inverters, and when trying to link with domoticz, I have the same red errors in the log as in your first post.
Did you solved this finaly?
If you have any clue to help would be great.
Thank you

Dear Octy,

Finaly I can get all inverters information except battery SoC, voltage and current.

Did you find a way for those?

Thank you
