Not really. The C7 was set to power 8, for example. The higher the power the stronger the Zigbee signal. Taking it up to 20 may interfere with Wi-Fi devices running on 2.4ghz band.
Not being able to pair them. They migrated ok originally back in the spring. I had to refresh them once or twice and they were fine. But since I tore every down and started over they donāt want to pair. Even doing the in the clear and that other thing, They either arenāt seen, or if they are they never finish initializing. I also canāt get my non 3.0 singled bulbs to pair (those arenāt a big deal though). I changed the channel the other day. That didnāt help. My powers was actually on 16, I dropped it to 8 as @Eric.C.Miller suggested. Iāll try pairing them again and see if that made a difference.
Yeah. Iāve done that several times. The out door seem to be a bit worse than the indoor. Iāll try it again now that I reduce the power. Maybe that will make a difference.
Are you having these issues on the original hub or with the replacement?
The replacement. I didn't think much of it since Iāve seen other reports of zgbee issues. I never had to pair directly to the first hub, that was migration, and this hub originally was migrated from the original C*, that was migrated from the C7. last weekend I took everything down, reset the hub, then rebuilt the meshes. That is what finally fixed the HomeKit issues, which led me to believe there was something in the initial migration that was causing the issue.

Some of those reports you've seen have been resolved by replacing the hub. Will take a look at your engineering logs, and will follow up with you on our private messages.
I just tried it again with the power dropped to 8. Earlier in the week I changed the channel from 20 to 23 on your previous suggestion. Now the difference tonight, I was getting it to actually find the device each time, but it would get stuck in initialization. I have tried it the regular way, a few times painting in the clear , and avoiding Zigbee 3.0 repeaters. All doing the same thing.
For giggles, have you tried dropping power to 4? Dropping to 4 and going out to ch25 were 2 key moves for me getting my C8's ZB finally stabilized.
My conclusion is that -- for me -- my ZB mesh on C8 doesn't like direct connections; things work best when my repeaters are carrying the load, so lowering the C8's transmit strength as much as possible by dropping to 4 and going out to ch25 was clutch.

Still no dice on the C8. 4 power, channel 25.. nada.. finds the device, but never finishes initializing.
Nuts. I feel for ya, though... Navigating this is hella frustrating. The other thing that finally shored things up for me was removing the only two ZB1.2 repeaters I'd been happily using for years -- my 2 Halo smoke detectors.
So, was my fix about doing 1) ch 25, or 2) power 4, or 3) removing those Halos? Was 1, some, or all of things?
Were the Halos bad because they were some semi-sketchy ZB implementation that was OK on the C7 but not good enough for the C8, or was it just the fact they were 1.2 (and not 3.0)?
No idea about any of those answers, but I do know those are the 3 things that finally stabilized my zigbee, and it's been going strong for many months now.
Good luck, and hang in there!
So, Iām literally Down. To 7 zigbee devices. 4 Innr bulbs (zigbee 3.0), 2 outdoor and 1 indoor Hue Motion sensor. The Innr bulbs paired ok. Itās the motion Sensors, a hue bulb (no longer using), and some singled bulbs also no longer using). So, really the issue comes down to these hue motion sensors (and I remember they were an issue for others before). I can work around them, put them on a C7 and mesh them to my automation and apps hub. Even on the C8 they would be meshed. Itās just a three way mesh rather than a two way.
Do you have any repeaters other than the Innr bulbs? Since you only have a few devices, I would be interested if you reset the Zigbee radio and leave the bulbs out, if the Hue sensors are able to join easier. But you'll need some other repeaters to keep the Zigbee mesh strong. I don't have any Zigbee bulbs in my mesh, and didn't have any problems pairing Hue sensors, I wonder if the bulbs are the problem and not the Hue motion sensors.
I can try it. the good thing is with so few Zigbee devices, it isn't a big deal to start over with them. I think I have an old ST Zigbee outlet I haven't used in several years. No idea where to put it though as the three sensors are on opposite sides of the house.
I guess that could be. To be honest, if it's THAT easy it could be a solution. I included my first two matter bulbs, and so far I like what I'm seeing. If resetting the radio and doing the hue sensors without the Zigbee bulbs works, then gee, just twist my arm a little harder to buy more stuff would ya?! And conveniently Amazon has a $9.99 coupon on those same bulbs right now.

Appears I finally got the Hue outdoor motion sensors. Indoor still don't want to work. It sees it, but still gets stuck in initializing. Here is what I did.
- Removed all my sigbee devices (in this case 4 innr Bulbs).
- Set the Radio power to 8 and channel to 25
- Reset the Zigbee (twice, second time just to be sure)
- Reboot the zigbe radio (once)
- Paired while exchanging keys in the clear
The outdoor paired on the first try. The indoor never did pair this way.

Please ignore if this question has already been asked and answered...
Do you have a Philips Hue bridge? If so, have you tried pairing your Hue Motion sensors to the Hue bridge, then allowing the Hue bridge to update the firmware on the Hue Motion sensors, remove them from the Hue bridge, and then try paring them to the Hubitat C8 hub?
Just an idea to make sure the motion sensors are as up to date as possible, to see if that has any impact.

Yes, I do, and Yes I did. They are up to date, and the bridge is up to date (verified that yesterday). They pair just fine with the hue bridge, and they pair just fine with a C7. They just apparently despise the C8.
I remember when the C8 first launched there were a lot of problems with them. Even for myself (since they were migrated) I had to go out and push the button a few times to get them to stick. But I never had the issue pairing them until I fully removed them and reset the Zigbee (twice now). I'll leave the one that i did get paired where it is. I'll throw the other on a C7 or on the hue bridge. It's more of an OCD thing than a necessity. I would point out as a word of caution however to others that may try to add Hue sensors to a C8, that they may run into some issues making it work. I think Hue Sensors on a C8 is definitely a YMMV thing.
Also, as a follow-up note, I was not pairing these in the location where they will be used. I was pairing them about 2 feet from the hub. I just tried it less than 6 inches from the hub, pairing in the clear is still getting stuck in initialization.

Man, that is frustrating... A month or two ago, I had one (HE paired) Hue indoor sensor I removed when I got a presence sensor, but then I decided to use both, so I brought the Hue indoor back in and had no issues doing so (it paired in-place fine with my C8).
On a C8, which antenna is the Zigbee antenna? i have one other off-the-wall thing I can try. I have a second C8 without antennas. I'm thinking taking the Zigbee off, putting it on that one and seeing if the problem is still there. that could at least indicate if it's a hub/ radio issue.
UPDATE:
Finally got the bugger to pair to the original C8.
Additional Step:
- Shut down the Hue Hub
- Disabled Zigbee radios on all the other hubs (I actually thought they were all
disabled already). - Paired exchanging keys in the clear.
Finally worked on the third reset and retry..

Thanks for the update. So it sounds like the bulbs were the problem. We are aware that some users mixing Zigbee 3.0 repeaters and non Zigbee 3.0 devices may affect pairing.
