I tried reading on the forum and the github issues and it seems that the Zigbee binding is supporting some remotes, but the Switch Mini doesn’t seem to be configured correctly. It shows 3 Dimmer channels, but no channel can really be changed, as they are connected in a wrong way.
The logs see all the commands being sent:
(I pressed all three buttons from top to bottom first short and then long, so the OnCommand is the “up” button short press, MoveWithOnOffCommand is th “up” long press and so on)
I have seen some topics about creating a static thing yourself (A channel converter for buttons (e.g., on remote controls or wall switches) by hsudbrock · Pull Request #284 · openhab/org.openhab.binding.zigbee · GitHub) and one try to get the Switch Mini to work (Support for ZigBee remotes · Issue #37 · openhab/org.openhab.binding.zigbee · GitHub), but I’m not sure that I’m able to modify the binding myself, as I have no infrastructure or experience to test it. I can however provide more logs or details if that helps.
Or is there maybe another way to access the “raw” Zigbee messages to use them in rules?
