One of the top selling Zigbee-based wall switches on Amazon in the US is the Leviton brand. I just installed one and got the Raspbee II with Home Assistant, just to realize it is not support by deCONZ, which was surprising.
The model I have is the Leviton Switch DG15S. There is a dimmer version too which would be ideal to support too, DG6HD.
If there is a reason it is not support, please let me know so I can return it.
