Hello, I've modified a repo for seplos and adapted it to report telemetry data directly to Home Assistant, you can use an RS232 interface with ESP32 or if you have an ESI interface and by any change they've given you the wifi module with esp32 inside, you can just upload the program there and specify everything you'll need: https://github.com/SaschaKP/esphome-pace-bms (of course you can use an ESP32 or whatever you have with an RS232 interface)
