Hi, I have been looking for a way to locally read my Growatt 4200 inverter, saw your code, and pictures of using the RPi for it. But what converter did you use ? Cannot see it from the picture you posted. Will try to integrate this with my HomeAssistant/Grafana setup

Thanks !!

Hi @bigfloor sry for the late response. The tested inverters are mentioned in the readme. Though I think the registers can easily differ for different firmwares or versions of the inverter. I didn't find the time yet to analyze it.

Hi, Thanks for the reply, in the meantime I have switched to using an ESP32 wit a MAX-TTL converter, connected into Home Assistant (with ESPHome). Works great, is cheap and ESP32's are easily available.
