That’s incorrect. The Zigbee channel is constant (much like a WiFi channel on an access point). It only changes when someone changes it on the coordinator. Otherwise, it’s a static value. Devices can choose different routers (parents) in a mesh depending on various traffic conditions (and other criteria) within the mesh. But even that is largely static as long as the router topology doesn’t change very much.

I have also had random nightmare issues with my zigbee network but narrowed it down to interference. Moved my 2.4GHz WiFi channels to one end of the spectrum and the zigbee down to the other end (including Philips Hue). All necessary due to installing a Wiser heating system that also uses a private zigbee setup (but has no method for changing channel).
I also reduced the power of the 2.4GHz WiFi to the minimum to keep WiFi IOT devices online.
We are fortunate that we live in a relatively unpopulated area with minor WiFi interference from neighbours but I can imagine in more densely populated situations, a neighbour could have installed something new that forced your own WiFi to move to different channels that are then causing problems with your zigbee signals.

The initial post was about finding instructions for transitioning to a new radio. While there might be underlying factors contributing to the problem, such as Wi-Fi channel conflicts, it appears that there’s been no significant change in the situation for @kenwiens and the fact that he cannot access the logs adds to the complexity. In my opinion, considering the possibility of hardware failure and the relatively low cost of this type of diagnostics and especially being somewhat remote, it seems like a reasonable course of action. At worst, it might confirm that there was no issue with the ZigBee module, leaving him with an extra one! n

Thank you. I did enjoy watching this thread go down a variety of different directions, and did enjoy learning a few new things. In the mean time, I have ordered the replacement dongle and it should arrive by the end of the week. As you say, at worst case I have a spare.
Any thoughts on my original question as to what is involved in putting a new dongle in? Will the network need to be rebuilt or is there some magic behind that “migrate radio” button that does it all for me?
thanks,
Ken

I have wondered about this, but less since it happened to both TR and Sengled devices. However I would like to confirm the firmware.
It’s interesting what you say about OTA and ZHA and the config.yaml entries. No where did I see any reference to this before, and even in extensive discussions with the ZHA team, they never pointed this out. How did you know about this? How did you know to even look for this?
I thought I had read everything there was about the ZHA integration - but obviously not.
I assume this is just for automatic updating though? The fact that ZHA seems unable to a) get the firmware version on the device and b) get the current firmware version level from the manufacturer - is still a different issue?
Zigbee Home Automation - Home Assistant (home-assistant.io)
I was researching to see if Zigbee updates were automated. With the intent of making sure it was NOT enabled on my system. I do not encourage auto-updates in Home Assistant. The chances of a breaking change automatically installing is too much risk for me.
I agree, especially when one is remote! At first glance I thought these lines in configuration.yaml were necessary for zha to even find the firmware version, then I reread and saw it was for auto update. Given ha can’t seem to send any commands to these devices, I couldn’t expect it to do it’s firmware upgrades.
So, forget the detour into the weeds. What about asking your on-site friend to take a couple of the Zigbee plugs to their Home Assistant installation to test and update them?
