Xiaomi Mi Scale

Code to read weight measurements from Mi Body Composition Scale (aka Xiaomi Mi Scale V2)

Note: Framework is present to also read from Xiaomi Scale V1, although I do not own one to test so code has not been maintained

Setup:

1. Retrieve the scale's MAC Address (you can identify your scale by looking for MIBCS entries) using this command:

$ sudo hcitool lescan
LE Scan ...
F8:04:33:AF:AB:A2 [TV] UE48JU6580
C4:D3:8C:12:4C:57 MIBCS
[...]

1. Copy all files
2. Open Xiaomi_Scale.py
3. Assign Scale's MAC address to variable MISCALE_MAC
4. Edit MQTT Credentials
5. Edit user logic/data on lines 117-131

How to use?

• 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

Home-Assistant Setup:

Under the sensor block, enter as many blocks as users setup on lines 117-131 in Xiaomi_Scale.py.
