Return battery voltage, too

[opape]

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

View lywsd03mmc fork. With AtcMiThermometerClient you can retrieve thermometers data without connecting. Limitations : can't get firmware and hardware revisions, can't get history.

from lywsd03mmc import AtcMiThermometerClient
client = AtcMiThermometerClient()

client.get_datas()

for thermometer in client.thermometers:
    print('----\n', thermometer) # print all data `
