Physical ZWave switch unresponsive

I had been running a couple Inovelli light switches for over a year on SmartThings with no issues, and switched to Hubitat at the beginning of the year. I bought some more ZWave things, and got it all set up in december.

I have a recurring issue (cant pinpoint the "why") in that my ZWave devices just completely stop responding. I physically interact with the light switch, and nothing happens. It even happened to my Zen MultiRelay once (maybe a fluke? this is in infrequent)

So, i have 4 light switches (1 inovelli, 3 zooz) and a Zen MultiRelay that all have had this issue. I lose one or 2 light switches a month.

To fix: Flip breaker. They are back online in 30 seconds like nothing happened.

Can someone give me some hints here? I have excluded/included, repaired, even yelled at them. Nothing works except the breaker flip.

Currently, 0F (Front Door Lights) is dead, and i dont know which breaker it is. SIgh.

Did you try the Air Gap?

There does not seem to be an airgap tab...is that for dimmers only?

I would assume the air gap would achieve a similar result to throwing the breaker (but without getting snowed on), but i dont have dimmers.

Maybe it's just the Toggle that doesn't??

I have GE/Jasco and Inovelli in-wall switches and dimmers and they all have an air-gap. I can see from Zooz's images on their website that the paddle switch doesn't have an obvious air-gap.. but their paddle dimmer does.

What firmware is that switch on?

I had this happen to one of my Zen22s yesterday. No response to Zwave, no response to physical interaction with the switch. I mean 100% nothin'.

So I did what any proper IT Engineer would do.

I turned it off and back on again, this time by throwing the breaker for that circuit, waiting 30 seconds, then turning it back on.

Issue cleared.

FWIW, this happened once to a different Zen22 under Smartthings.

It wasn't a blackout, or brownout, but a power ripple that seems to do it. A related subject. Just prior to this switch being unresponsive there was an audible crash / boom, a flicker of lights in the house. Shortly thereafter sirens.

I am assuming somebody ran over / into a transformer somewhat close by.

My Zooz switches are all 4.0 firmware.
No clue on the Inovelli.

Power fluctuations may be a thing, but I would hope my computer would crap out first. Theres just no way i could tell. Seems like it shouldn't be a thing though. Especially across brands.

Unknown on the firmware revision of my Zooz switches, not sure how to check, or even update within HE...

My computers are on UPSes so no they won't be impacted by a power blip. HOWEVER, all of my Echo devices rebooted, and 2 of them required manually power cycling to get them back online.

Garage light crapped out again. thats my 3rd light this month.
