I recently had a PV system installed with SMA TriPower X inverter and Sunny Home Manager 2.0 components. I was naively expecting integration into my home automation (home assistant) to be a breeze, as there are SMA integrations available, and how hard could it be, right?
Turns out I was optimistic, because apparently the X generation of inverters does not behave like previous devices, API-wise, plus the SHM2 only offers obscure broadcast messages and doesn’t even have something I would call an “API”.
There exist some projects out there that work with these devices, collecting the data and making it available eg via MQTT for integration with other systems, most notably:
Either of these do (resp. don’t do) some things that makes them not ideal for my environment - I want something standalone that is freely configurable with regards to where it pushes data, that can easily be deployed as a dockerized application. So I picked parts and pieces from these projects, and put them into a new project.
Core features include: plugin-style architecture for extending with additional data sinks&sources, SMA TriPowerX and SHM2 plugins, MQTT and HA-MQTT publication, decent (hopefully) documentation, mechanism/sample config for integrating with home assistant, run standalone or as dockerized application.
I like the results so far, this setup does work quite well for me - but as always, ymmv, so interest and feedback welcome!
