Just some minor things: all Github links in the starting post are ending in a 404 not found, can you update the links?
I’ve 2 issues with the Aqara Thermostat E1:
in the iOS app, one can not enter negative temperature offsets, since the keypad is lacking a minus sign
i can not set the “external sensor” mode for temperature in advanced settings, when i set it and save, it says:
Cannot read properties of undefined (reading 'replace')
in the little red feedback alert.
edit: oh, and under maintenance the recalibration button is in dutch(?), although the rest is in english. 
Thanks for the hard work!
