Z-wave light switches aren't working

Very frustrating. Since the GE switches are on the official compatibility list, I would contact support and have them look into it. It could be an issue with the mesh but it will be easier for them to see from their side.

If you do want to dig into it further yourself, this gives more details and how to troubleshoot:

( and, yes, the dropping off issue is typically with GE bulbs, not the switches. That’s why the bulbs are not on the official compatibility list, but the switches are.

There’s a different issue that can affect GE switches, typically about eight months after they come out of warranty, but that wouldn’t affect multiple devices. )
