How to integrate my APSystems ECU-B?

Third party integrations

I have a small balcony PV with an microinverter from APSystems (DS3) connected to an APSystems ECU-B. Is it possible to read out the data and integrate this into HA? This could be very helpfull for some automation tasks i’m thinking of…

If you haven’t found it yet, this works for you: GitHub - ksheumaker/homeassistant-apsystems_ecur: Home Assistant custom component for local querying of APSystems ECU-R Solar System

Yes, thanks, i already found it. Was a little bit of extra effort to get that installed, because you need to add this extra repository, but finally it works like a charm.

Does it work using Zigbee?

The inverters talk Zigbee to the ECU (alternatives for the ECU can be found on the internet). The integration uses TCP commands to query the ECU.
