C7x5,C8x1,C4x2.
2.3.9.150 on all of them.
3 have active zigbee radios, 2xC4, 1xC8.
Zigbee scan shows the correct 14,20,26 chanels.
There are 2x on #25 and i would like to identify where that is coming from!
Neighbors?
I wouldn't put a ton of faith into those readings. Sometimes that chart shows cached Hubitat hubs where you changed channels. Other times it is like you say, neighbors, but without snooping around in their home or asking a bunch of personal questions, I am not certain how you would know it is them. In some areas, utility meters are Zigbee as well.
I am not sure how you would tell exactly what these are, although you could try matching and cross referencing the MAC addresses with every known device in your home.
This is one downside of Zigbee, that 2.4Ghz spectrum can be quite crowded.
One more possibility.
Apparently there are Zigbee radios in many Amazon Alexa devices.
I have no idea what channels they are on, or how to change that.
Unknowns could also be your neighbor's Alexa.
