Hi there, I have this REV Ritter ZW WS wall switch which I tried to add to Homey as a generic device. I think the inclusion does work but then it won’t show up in Homey. When I try to add it again it says something like “allready included”. I have to do a general exclusion to start over again. Im not very familiar with Z-Wave and a Homey beginner (got mine last week, very exited) but I am willing to go the extra mile of “customizing” stuff. I’m no developer but network/server admin and not afraid to get a little technical. Any ideas where to start? TIA ![rev%20ritter](https://us1.discourse-cdn.com/flex025/uploads/athom/original/2X/6/6a3e219fd8331d1d8d283248b411d702e7eb4e06.jpeg) ---

Yes, as I wrote, I got this. > [@neobiotics](#): > > I have to do a general exclusion to start over again. I can then include it again, after that it won’t show up in Homey. So I think there is no driver. I think I did not make my question clear enough: Is there a way to use such a simple device like a switch without a driver? Or can I “tinker” something? Where would I start?
