Just came across this, which sounds similar:

Switches not working after power outage

Hi inovelli team, Just recently, we experienced an extended power outage (about 24 hours) and when the power was restored, a significant number of our LZW30s aren’t working. Here are the different types of behavior for some of the dimmers: LED bar shuffles through three colors (red, green, blue) and clicks about once every three seconds (3-way dimmer with dumb switches) LED bar flashes rapid red (single light dimmer) Light will not dim to 0 (single light dimmer) Any hope to get these fixed …

@Eric_Inovelli : is this the reported behavior when a red series dimmer suffers power surge damage?
