Was there a recent firmware update? Last night my goodnight automation ran but most of the items failed, lights left on doors left unlocked etc. Most all my devices are not working now. If I turn device health on most show unavailable. The few that show available either don’t respond to commands or take 10, 20, 30 seconds or more to respond. The last time this happened, it was a firmware update that caused it.
I have tried rebooting my hub. I have tried the z-wave repair tool, I’m not sure what else to try.
