This morning when we woke up, our GE dimmer switch was continuously cycling a set of lights dim to bright to dim. I've heard of these devices failing such that it loses all control, and I've had a few of those. But this is something I've not seen before.
The turn-on at 6:28AM was not done by anyone in the household...
Is it time for a new switch? Has anyone seen this before and can offer a suggestion?
The fact that the event is "physical" indicates that it isn't the result of some Hubitat-driven automation going amok. I would suggest pulling the air-gap switch, waiting 30 seconds, and pushing it back in again.
I had a few of the GE switches fail in this manner. Not dimmers, however. Mine just kept turning on and off. As @aaiyar suggested if air gapping doesn't fix it then you will probably have to replace it.
Check when you purchased it, because some of the switches had 5 year warranties. I just sent a switch back to them without any receipt and they say they will replace it. They send you a shipping label so it's no cost.
