I am struggling with my entire z-wave network becoming unresponsive, only to be resolved by a reboot. This can happen 3 times in a week, or once every 2 weeks. I cannot find a pattern. I will detail what I've done below to troubleshoot, but I am at my wit's end. I've gone so far as to upgrade my hub from a c7 to a c8, and the same thing is happening, so something is absolutely wrong on my end.
Running C8. I have approximately 65 z-wave devices on my network (in addition to probably 20 zigbee, konnected board, and links to several other systems - caseta, hue, sonos, google home, govee, lifx, myq, etc.) So my system is pretty elaborate.
I've noticed no pattern to when it freezes. Examples:
+Last night I pulled into the garage around 3pm and noticed the lights didn't turn themselves on, noticed no z-wave devices were working
+This morning, I noticed fence lights in back yard were still on after sunrise, this led me to notice that again, all z-wave devices frozen
Nothing abnormal is in the logs (no errors or warnings) and I see no "running jobs". I have no ghost devices (I bought a stick and went thru removing them all back in November while trying to troubleshoot this). I see no hanging rules or devices; if I sort my z-wave devices by "last message" date, all seem to be being used frequently (no unused devices). Been using this system for about 5 years, and I know everyone will say "what did you change?" Well, TBH, I change stuff so often I can't answer that as I don't really know when this began.
If you were faced with this problem, how would you troubleshoot?
