Hi @BluePicture
I don’t have zigbee or zwave dimmers in use, just smart bulbs.
There are references in the forum and a driver for Moes MS-105Z dimmer zigbee.
In zwave the Fibaro dimmer2, FGD-212, has with good references.
It has official smartthings driver and another that I adapted with more custom settings and buttons for scenes.
