I’m having some issues with my battery monitoring. I have a ESP32 and a Basen green 12V 100Ah battery with the xiaoxiang BMS. The ESP is placed just beside the battery but it does’nt connect to it. If you restart HA it can sometimes connect and show all parameters. But mostly it doesn’t connect to the battery. Any ideas?
Hello @burnspc, thanks for your great contribution. I have tried to get my unit SP04S034L4S200A connected but until now without much luck.
All values are returned as “nan”.
I have included parts of the log and the home assistant ESPHome configuration underneath and hope to get some pointers to fix this.
It might be relevant that I have accidentally set a bluetooth password on the device. I did try to remove it by changing it to 000000 but not sure whether that helped.

I am hopeful this thread isn’t too long dead to be dug back up.
I have a Chins 400 amp hour Bluetooth Smart LiFePO4 battery that uses BAT-BMS for monitoring, I am wondering if there is a way to get this worked into a Home Assistant Dashboard. It is my one missing piece for my RV monitoring dashbaord…
