And it is down again this morning! I'm looking at the logs and nothing stands out. I'd say that the zigbee traffic was quite low.
The top 4 lines on this log are all z-wave. The 5th line (dev: 37) is the last zigbee transmission.
It seems that my Hubitat has selected zigbee channel 20
It seems that my Verizon quantum router had its 2.4ghz network on. I've shut that off as we don't use it.
I've forced my netgear nighthawk mesh from auto to channel 1 . My understanding is that wifi channel 1 and zigbee channel 20 to not overlap.
Hopefully, that will do the trick. If not, my next attempts will be...
-
shut off HE and all zigbee devices for 30 minutes. Turn on HE and then restart all zigbee devices starting near and moving away from the hub.
-
relocate the HE hub.
