Is there a standard for MQTT topics/names for a PV inverter? If so, it would be nice if there is a "hardware" plugin for domoticz that receives the data. I have been searching but could not find anything useful yet (only a few using the probably China-based Growatt servers). Any pointers?
Thanks!
Background:
- I've just installed a Growatt solar power inverter, and would like to connect it to Domticz over MQTT
- I may need to have other receivers in the future, hence MQTT
- I'd like to deploy a Raspberry Pi to interface the inverter (RS485) and publish the telemetry over MQTT
- I do not want to use any internet-based solution
