I have two of the Jasco Enbrighten 43080 Zigbee Dimmers (the 2020 version) -- and on each of them I've had them lock up requiring the power to be cut (pulling the air gap does not work).
When this happens there is no response at all - no indicator light change - no light bulb change - no sign of life. I've had this only happen once on each one, and no consistency from what I can see. I've not seen complaints in reviews about this (such as how comments like this are plentiful with the Leviton z-wave dimmers), so I'm wondering if anyone has any suggestions of what could be causing this / had similar experiences?
I noticed that during my most recent issue - the switch stopped physically functioning last night - the night of December 2, 2020, however, the last activity reported in hubitat was December 1, 2020 (even though the switch was physically used many times on December 2nd).
I have noticed a number of posts regarding dimmer switches arbitarily locking up, and people assuming it's a problem with their dimmer.
As a backgrounder, I had about 20 old Linear original Z-wave dimmer switches, which about two years ago arbitrarily started slowly going from zero to 100 and back down again, maybe once a month per switch. I assumed it was the old Linear dimmers, and replaced them all (!) with Leviton or GE/Enbrighten Z-Wave plus switches. Now, the dimmers on those same circuits are occasionally arbirtrarily locking up entirely, as you've described here. It only happens on switches that are not on a three-way circuit.
It's totally bizarre, and I can only conclude that there is something that happened in a Hubitat firmware update around 2022 that is causing this to happen. It can't possibly be the switches, since it's three brands on the same circuits. I've tested the voltage and everything is stable and fine. I'll post this separately and reach out to Hubitat as well.
