Xiaomi and Aqara: shame on your for designing the worst battery cover case ever - impossible to open. This model is a screwdriver for this…
Opening this sensor is an horror:
The little screwdriver will print in 10-15 minutes.
I printed at 0.2, 3 walls, 15% infill, PLA.
And made it red to showcase my anger at this device. (I have 15 of those in my house, all over the place measuring temperature. They are quite reliable… nevertheless).
Instructions on how to open the Aqara / Xiaomi back cover:
(Marvel at the cynicism that such instructions need to exist)
Place screwdriver in the slot
Push down HARD and turn counter-clock wise just a bit.
Just turn A BIT counter clock wise.
Added tip:
Voila.
