Zigbee Buttons with Direct Association

My Ikea Styrbar remote has worked very stable in the past few months... What problems do you have?

All Ikea (also Tuya) remotes support Zigbee Groups, although it is a bit tricky to set up. As I don't have a practical use of the Zigbee groups (almost all my lights are controlled via CoCoHue), I just had some successful tests, but haven't digged further.
