Ok, now, step by step, is more clear for me.
As reported in the following snapshot, no trigger channels are present in the thing, and also no events are added in the event log when the button is pressd, in any way (short, long, duble, …).
The dimmer channel reported as “Level Control”, do nothing. I can’t use it in any rule and linked to a dimmer Item do not reflect any change.
Seems to there some problem to convert the Zigbee entity to a thing with proper channels.
Others strange channels are the “Battery Level” and the “Battery Voltage”. In this case “Battery Level” could be the “Signal Level”, and “Battery Voltage” correctly the battery voltage. I suppose that becuse is trange using 2 channel to say the same thing, and because linking this channles to Items, show somethings like “2.9 (V)” For Battery Voltage and “49%” for “Battery Level”. A CR2032 battery at 2.9V is 95% to 98% of charge.
Update:
This is the zigbee XML File of Ikea switch:
