Python library to read Renogy RS232 compatible BT-1 bluetooth adapter. Tested with Rover / Wanderer series charge controllers and Raspberry Pi Zero 2 W. It might also work with other "SRNE like" devices like Rich Solar, PowMr, WEIZE etc.
pyhton3 ./example.py
Make sure to update mac_address and alias in example.py. It has APIs to continuously read data or turn on/off load.
How to get mac address?
Use any BLE scanner apps like BLE Scanner and look for devices with alias BT-TH-XXXX..
