For now i did this

def process_payload(self, params):
    log.debug(f"Processing params: {params}")
    params.pop("bms_slave_bmsSlaveStatus_1.packSn", None) 

But i think should be better solution.

[typicalaimster]

    params.pop("bms_slave_bmsSlaveStatus_1.packSn", None) 

Note: If you have two batteries plugged in you'll need to do this to both 1 and 2.
