Hi there, it seems that I have another firmware version on the sensor and due to it the script fails with 'expected a character, but string of length 2 found'

pi@raspberrypi:~/mitempjj $ python3 /home/pi/mitempjj/poll_sensor.py
Getting data from Mi Temperature and Humidity Sensor

    battery,temp,hum = poll(args)

    self.battery = int(ord(res_battery))
TypeError: ord() expected a character, but string of length 2 found

the firmware version on the sensor is 1.0.1_0093

Perhaps it would help to change version of mitemp-bt in requirements.txt from "mitemp-bt==0.0.1" to just "mitemp-bt". Unfortunatelly I can't test as I only have 1 of these old round sensors. Please note, it will not work with new sensors, that use encryption, only with the one in the picture.
