I suspect that the biggest problem people have with Zigbee has to do with WiFi. I locked my router to use channel 1 and have my HE on channel 25. My Zigbee mesh is rock-solid and reliable. I had tried using a WiFi extender and did have problems. I realized my house is not big enough to use the extender. After I eliminated the extender and set the WiFi channel to 1, no problems.
Based on @HAL9000's recommendations/comments, I unplugged all of my Apple Home TBR's (2 x AppleTV 4Ks, 1 x Apple HomePod Mini, and 1 x Aqara M3 Hub.) After doing so, sure enough I could no longer control the GRILLPLATS outlet from the C8ProT hub.
Also, by looking at the C8ProT's Settings->Matter Details page, I could see that the IPv6 address of the GRILLPLATS plug was different from all of the other MoT devices that were paired directly to the C8ProT hub's Thread radio. See the following post for details.

Mike:
I've done some additional testing with the infamous Grillplatts. I found a couple things that might be of interest.
I can pair the GP with Alexa. In the pairing process Alexa offers 3 different thread networks: the amazon network, my Apple Home network, and the Hubitat network. I chose the Hubitat network and was prompted to enter the network key. I referenced thread details page in Hubitat and entered the key manually because I couldn't figure out how to copy and paste it. As you know, it's a LONG string of hex digits. I entered the string and checked it twice. I received a message saying the key was incorrect.
Question: why does choosing the Hubitat network require entering the network key? Choosing Amazon or Apple network does not require this. A second question: Has the process of joining the Hubitat network from another system like Alexa been tested? It's certainly possible that I entered the key wrong but I did double check it. So I paired the GP with Alexa instead.
I successfully paired the Grillplatts with both Homekit and Hubitat using setup keys generated by Alexa. I know that the real goal is to pair it with the Hubitat thread network, but I can at least use the device from both Hubitat and Homekit. Response time is instantaneous. This beats throwing the device in the trash (i guess).
The Eve iPhone app shows the GP as a router device connected to the Amazon network. Thread Doctor shows an unconnected network showing the Amazon border router with the GP connected to it.
I hope this helps a bit.
The Hubitat network key is shown on the thread details page as you noticed you should be able to copy that directly and use that in the Alexa prompt.
There's almost no way you could type that in by hand and get it right
Understatement of the year...
Yeah.. I copied it easily from my computer. But i was using the Alexa app on my iPhone and couldn't figure out how to paste it. For some reason I cannot ping the address of my Echo nor attach to the device with a browser.
In any event, I'm not going to attempt to repeat the whole process. Took me to long and at least I have the Grillplatts working in Hubitat and Homekit. I think I needed to enter the key is because it has not been entered into my phone keychain. The Home network and Amazon network keys have probably been copied.
Have you been able to add a device to the Hubitat thread network using the network key process from Homekit or Alexa?
No, I haven't tried that. Haven't had any need to try it yet.
Is the end result of copying the key and pairing as described to the Hubitat network using Alexa that the spatzplat is on the Hubitat network independent of other TBRs?
unlikely to work, but ive been wrong before
I think I have figured out a way to copy and paste the Hubitat network key into the Alexa app. That will relieve me from trying to enter the key manually. I have a new Matter/thread device due to be delivered tomorrow. I'm going to first pair it with Alexa and see if the Alexa app prompts me to choose a thread network. I'll choose the Hubitat network and paste the key.
We'll see what happens.
