Thank you, I just downloaded and installed your firmware on the ESP32 module I had. Ordered other small hardware, will try this with my 100balance BMS and update here.

Ciao Kapilag123, thanks for commenting . Please note the project “Smart BMS data Extractor” project is not based on ESP32 , it is based on ESP8266 – NodeMCU kind. Migrating to ESP32 is almost done but never had enough time to complete.
