# Code to read weight measurements fom Xiaomi Scale V2
# (Framework is prsent to also read from Xiaomi Scale V1, though I do not own one to test so code has not been maintained)
# Must be executed with Python 3 else body measurements are incorrect.
# Must be executed as root, therefore best to schedule via crontab every 5 min (so as not to drain the battery):
# */5 * * * * python3 /path-to-script/Xiaomi_Scale.py
# Multi user possible as long as weitghs do not overlap, see lines 117-131
#
# Thanks to @syssi (https://gist.github.com/syssi/4108a54877406dc231d95514e538bde9) and @prototux (https://github.com/wiecosystem/Bluetooth) for their initial code
#
# Make sure you set your MQTT credentials below and user logic/data through the environment variables
