I’ve just released the v1.2.0 version of the app to the test environment of the app store: https://homey.app/a/com.xiaomi-mi/test/
Main change: Add support for the Aqara T1 switches
SSM-U01 (with Neutral): onoff and support power measuring,
SSM-U02 (without Neutral): only onoff,
Both devices have settings to determine the switch type (toggle of momentary).
Enjoy!
