I have been looking all over but can't find anything like this. It seems all of my Zooz Zen31 z-wave led strip dimmers (7 of them) stopped turning on and off at basically the same time.
Most of them run on a basic rule to turn on at sunset and off after bed. They were rock solid for months and one night I noticed they were not on. Then I recognized they had not gone on in several days. I tried to manually turn them on through the hub and they would not respond. This was several months ago, I have tinkered with several things but and the situation has not changed.
My Hub has been sending commands the whole time, but the devices are not "reacting" as far as I can tell. Every day the logs show on and off commands but the lights in reality are not working. They are responding with energy consumption of 0W. I have several other z-wave devices that continue to work as normal on the same nightly rule. As far as I can tell the Zen 31's still appear as part of my Z Wave mesh. It's like they are ignoring the commands.
Obviously something had to have changed, but I cannont think of what it would be. I did not update my Hubitat OS or the device drivers, nor did I add any new devices at the time they stopped working. I have read energy logging can cause an issue but switching that off has not changed anything.
I am hoping this is not some simple mistake on my part, but I'm fairly novice and I'm out of ideas.
