Hello everyone,
I have four Victron PV charge controllers which I read out via the RS485 interface using one ESP8266 each (PV module power etc.) and read into Home Assistant. Some time ago, one of the four ESP8266s in HA no longer transmitted any values. Now data is only occasionally sent to HA from perhaps one ESP. I have no idea why this no longer works. I can read out all charge controllers locally, but not in HA. Unfortunately, I have to admit that I am not a professional in HA. I watch a lot of videos and put something together.
Unfortunately, I can’t get any further here. Does anyone have any idea what this could be? Was there ever an update in HA where I had to do something?
I would be very grateful for your help.
Regards Beda
