It connected when I first turned it on, but the hub thought it was an “Open Door” sensor or some goofy thing like that, so I “Excluded” the thing, but I can no longer add the device! I tried several DHs, but nothing works! I just opened a ticket with the manufacturer which I hope can help, otherwise, I’ll never buy another Zooz device because I paid $30 for this and the only thing I got is the CR123 battery that’s of any use.
Zooz is a very popular brand in the community and their support is usually very good, so hopefully they’ll be able to help.
Right now SmartThings itself is in the middle of a huge architecture transition but a lot of the new features are in beta and many brands are being affected by weird glitches, including misidentification when joining. (Just last week there were multiple reports about GE Switch problems, for example.)
During the transition I’d hold off blaming any third party brand: it’s more likely to be a SmartThings transition issue right now.
