I have two of the new LZW31-SN Red Series Dimmer Switches. Both in neutral-wire single-pole installations, connected to SmartThings.
Over the last three days, one or the other or both of them suddenly become completely unresponsive. I’ll try to turn off the light, and nothing happens. Physical switch does not respond, trying to use SmartThings does not work, nada. Regular on/off button press does nothing, double/triple taps do nothing, holding up/down for dimming does nothing, favorite button does nothing. The only way to get it to respond again is to reset the associated breaker.
I have a number of other Inovelli switches around the house and no shortage of other Z-Wave repeaters, and these two switches are the only ones with problems. Wife Acceptance Factor on these is now zero, so I’ll probably put back the dumb switches that were there before unless there’s an easy solution here.
