I also experience problems with the Aqara Opple 6 Button Switch.
The initial setup worked just fine, but after i restarted my Rasp-Pi, all the device information was gone and the Buttons did not work as expected. Now when i re-pair the device, it seems like only the upper 4 Buttons generate any events, but they dont distinguish between the different types of presses (single/double …) Here is a screenshot of the events triggered by the upper four buttons
Using the template to call any service doesnt work, how matter which button i choose.
I would be happy if someone could help both with the setup problem and the data loss problem when restarting.
