Xiaomi Miija (Temperature and Humidity)

Apps
1

I’m happy to announce, that the Xiaomi Miija app is available in the app store. Currently, it supports the Xiaomi Mi Temperature and Humidity monitor (BLE), with the ATC441 protocol, flashed with a custom firmware.
The custom firmware can be flashed from here GitHub - pvvx/ATC_MiThermometer: Custom firmware for the Xiaomi Thermometers and Telink Flasher .
I’m not a developer, but in case of any idea, I’m happy to do what I can.

Thanks for adding this. I do have an issue with reading the correct values in Homey.
After flashing the firmware, all looks well in the Telink Flasher app:

These values are also shown on the display.

However, the values in Homey are totally off:

Does anyone have an idea on how to fix this?

Hello DGalama,
