Hello. I’m trying to report the battery remaining value from an STM32WB55 microcontroller.
I am reporting the battery voltage and remaining percentage to the ‘PowerConfig’ cluster, but it’s not showing up in ZHA.
I assume it’s because the Zigbee stack from ST doesn’t seem to allow for changing the power source in the Basic cluster, so I am trying to see if it is possible to change the node descriptor via a ZHA quirk and not having much luck.
So far my quirk looks like this:
class STM32Sensor(CustomDevice):
"""STM32 sensor device."""
def __init__(self, *args, **kwargs):
"""Init."""
self.temperature_bus = Bus()
super().__init__(*args, **kwargs)
