BatMON is now more stable and latest release 0.0.63 even give more info, the main problem I found was in the JK BMS, many times it won't close the Bluetooth connection and it prevent BatMON to connect, we need to turn off and on the bms, with Victron shunt work without problems.
In my opinion for those with multiple BMS this is the best and easy to implement solution for HomeAssistant, no need for converters and ESP that only work with one BMS at the time.
The bt_power_cycle and be able to turn on charge and discharge of the BMS was a great improvement.
