NOTE: All Xiaomi / Aqara wireless button users
Hub Firmware 25.26 was released for SmartThings v2 & v3 Hubs in March 2019
The new firmware includes changes that “break” some functionality in the previous device handlers, but also allows for much improved functionality.
In order to fix the issues and add improved functionality, I have updated all Xiaomi / Aqara Button device handlers (DTHs). All SmartThings v2 & v3 Hub users are encouraged update to the newest DTHs immediately.
