Zwave wall switch suddenly offline

[Barkis (John C)]

Very interesting!

At present, I have a Zooz wall switch that got dropped from my ZWave mesh. It happened with the same switch last March and the “fix” was the same: use “ZWave Replace” and replace it with itself.

The discussion about this problem being unacceptable and having it happen when 1500 miles away from home is best kept for another time, so I won’t go there now.

But, I wonder if 1) it is a SmartThings problem rather than the switch itself, and 2) how many others have experienced this and blindly “fix” their missing ZWave device by “replacing” it with itself???

Obviously, it shouldn’t happen in a robust home automation system…

Experience with Remote Deployment: Sketchy

Alas, same problem has recurred: I am 1500 miles away from that location and five days ago the Zooz ZEN23 switch again went missing from the ZWave network. A piece of our security lighting that had been running smoothly is now not happening. An attempted remote ZWave network repair didn’t change a thing. Neither did remotely rebooting the hub. Since I coaxed the switch back to life last April, it has worked flawlessly every night until now. Simple Device Viewer reports the last event was received from the switch five days ago. Every other device is still on-line and checking in. Last time this happened, I was able to bring the switch back to life by doing a ZWave ‘Replace’ and toggling the switch a few times. But my arm isn’t long enough to try that until we return for the holidays. Is…
