Dome Siren just arrived today and I was having trouble doing the z-wave discovery, so tried to do an exclude. When I pressed the exclude button, it just says "Z-Wave Exclude Stopped":
Firmware 2.0.8.107.
Firmware 2.0.8.107.
It's supposed to stay in exclude mode for 30 seconds and it counts down the remaining time. Did yours just immediately say Z-Wave Exclude Stopped?
Yup, it immediately went to Z-Wave Exclude Stopped, never tried to do the exclude.
What browser?
Ugh! It's Edge. I use the dashboards on Firefox but my main browser is Edge. The exclude works on Firefox, I'll start using Firefox for all Hubitat stuff. Sorry for the trouble!
