When adding a HS HS-MS100+ via z-wave, it should show up as a "Zooz Motion Sensor ZSE18", which the second one I added before did without a problem, it shows up as a "Ring Alarm Retrofit" with all the sub-devices (contact 1 through contact 8).
Normally, I would think, not a big deal, simply change the device type to the Zooz, and it should be fine. Nope It does not remove the sub-devices.
Not a big deal, as the sensor works just like it should, but there seems to be no way to remove the sub-device leftovers from the incorrect Ring Alarm detection...
After resetting the device several times and adding/removing it in HE, it was added correctly. Not sure if it is a defective sensor or a bug in the detection routine, so don't spend too much time on investigating this!
I'm seeing a similar issue with my Homeseer HS-WS100.
I just received my C7 Hubitat hub today, and this is the first device I've paired...
