I don't know how exactly your set-up is like, but wherever antennas are, they will pick-up radio waves they "resonate" with. A Zigbee device uses the 2.4GHz ISM range. This means any 2.4GHz device, or emitter for that matter (such as microwave ovens or even USB 3.0 cables), along with other resonant frequencies (e.g. double or half the wavelength), will generate current at the antenna. This happens regardless of whether the chip connected to it can interpret the signals. When too much interference happens, especially at too high power levels, they generate a lot of current that could affect the (sensitive) electronics' function, and in extreme cases, destroy them. Essentially, that's how EMP damage works. In your case, it is possible that being in close proximity to those devices caused sufficient induced current to affect your C7 device.
I won't know since I don't work for Hubitat, but it's all in the way they designed their electronics. They may not have implemented sufficient shielding or grounding or filtering on the device. Or the Zigbee chip they used isn't able to deal with these situations as well as those other devices you have.
I thought that I might have found the issue and resolved it. But NO!
The zigbee radio shut off yesterday and did not restart. Since I rebooted the hub, the zigbee radio has turned off several times, but then turned itself back on again. Perhaps this is part of the .152 update? It seems to go down for about 7 seconds.
I'm glad that ya'll are restarting it now. Any idea why it is going down?
I just switched to C-8 and it went down also.
It did restart after 12 seconds.
Two days ago, Zigbee went down and did not restart on my C-7. I'm hoping that the C-8 always restarts. And hopefully, one day, you guys can fix the issue of it going down in the first place.
