I’ve also got a device type for the OSRAM dimmer, that is defined as a switch, rather than buttons (based mostly on the work or @Motley).
There is no binding to any other devices, so it’s basically a physical virtual dimmer switch ( how’s that for an oxymoron).
I use it with an adaptation of “Dim with me” to control a group of lights.
I was never able to get the continual dimming during a “press and hold” to work, so it goes up or down by 20 with each “press and hold”.
