@chris, I have a Zooz Z-Wave Plus Power Switch (ZEN15) that appears to not be in the zwave database. I have attached the xml file. I created an account on your site, but I’m guessing I need permission to add new devices. It doesn’t matter to me how it gets added!
Are you getting some/all of these items reporting below in OH?
