Two switches are supposed to turn on at sunset – now all they can do is this:
They are likely toast. I’d bet they both got hit by a surge or static shock on the line of some type… Are they on the same breaker perhaps?
Kill power at the breaker. Wait a bit and turn them back on. If that doesn’t work you may need to plan on using the ZWave replace function sometime soon I’m afraid…
Call Jasco support if you are still within their 2 year warranty
No, different breakers.
Yes, I think you are right–they are toast.
