Today I realized that all my Z-Wave window se sensors stopped working around 20th of May. No reaction, no update, nothing. Tried to repair the Z-Wave network but without luck.
Got the following response.
Nothing changed on the system so far, maybe an updated of my C7 caused this issue?
Any ideas what could be the next smart steps?
Shutdown, remove power at the wall for about 30-45 seconds, power back up.
Thanks @thebearmay that did the trick. All back to normal. You made my day.....
Now I would also suggest setting up this app which will let you know if devices stop responding / checking in. This would catch dead batteries, or a total zwave network failure.
