I get the following error message
Bluetooth command failed (code: 10, error: No attribute found within the given range)

Please, support getting the data from the periodic (in my device every 2.5 seconds) advertisements, instead of establishing a BT connection, to keep battery usage low.

Is there a reason why I shouldn't use data.battery here instead of client.battery?

I find that using data.battery is faster and as far as I can tell it returns the same numbers.

Please extend the structure SensorDataBattery with the voltage of the battery. The value is already present in the code, but it is not returned in SensorDataBattery.

    def _process_sensor_data(self, data):
        temperature, humidity, voltage = struct.unpack_from('<hBh', data)
        temperature /= 100
        voltage /= 1000

        # Estimate the battery percentage remaining
        battery = min(int(round((voltage - 2.1),2) * 100), 100) # 3.1 or above --> 100% 2.1 --> 0 %
        self._data = SensorDataBattery(temperature=temperature, humidity=humidity, battery=battery)

Thanks
