Node-RED

Continuing the discussion from How to create a new PV-inverter Dbus (+VRM) instance with Node-Red:

Interested to here where you go with this. I’ve got a Growatt inverter that I will be adding to AC out on a Multiplus II 6k5 and would like to control it from the Cerbo.

I’ve got a ESP32 connected to the Comm output on the Growatt and have it talking to Home Assistant now (this project). I could get the Cerbo to ping the Home Assistant API to make power level and on/off changes changes via Node-RED but it would be much better to have the Cerbo do it directly.
