Replacing the C8-Pro with my C5 solved all of zigbee problems. Now I am moving all of the zigbee off to my C7. Once done with this I will replace the C5 with the C8-Pro again. Then when done with that I will start moving the zigbee back on to the C8-Pro in groups to see if I can isolate which device(s) are causing the issues.
2/3 of my devices are z-wave. So I plan to either replace the zigbee devices with zigbee devices that are known to not cause issues or move them to Z-wave. I do need to leave some devices around to maintain a mesh for the devices I can't switch - two heated floor thermostats, a bunch of blinds, etc.
What are devices that people have had luck with? I am mostly looking for plug in modules that also repeat well.
Can't help you there.
Wish the Habitat crew would really look into this issue. I'm sure more people are having sporadic issues with their zigbee devices. I for one had both c5 and c7 hubs with no issues with either, but after paying big bucks for the C8 pro, have Siglend bulbs and Smartthings Water leak detectors dropping off and joining again in 2 days or so. I thought the antenna's were to help with connections. It's funny that it's only 2 bulbs and 2 water sensors that have had issues and everything else is working great and fast. Never had these issues with my older C5 and C7 hubs .

My Innr plugs have been reliable performers (and repeaters) - they are ZB3.0.
For me, one of the things that really helped with my C8/8Pro zigbee issues was making sure that ALL repeaters (i.e. mains-powered) devices were ZB3.0 (not ZHA 1.2). I still have some ZHA1.2 battery devices, but all repeaters are 3.0 from reliable manufacturers.
Spot on
Unfortunately, if you have Zigbee in wall outlets they MAY be ZHA 1.2 and not Zigbee 3.0.
Of course, they are handled as Zigbee repeaters.
How certain are you of that? I've actually been trying to determine which ZigBee protocol/spec/version the Jasco outlets use. There are zero markings on the units I have (43132s,) the manual does not say, and the official Jasco webpage is long gone. I did find one reseller's page that claimed it was 3.0, but I'm not totally sold on that being authoritative.
I just checked the GE/Jasco website and they do claim that the 43102 is a Zigbee 3.0 device.
However, I seem to remember the box that mine came in, and I thought that it said ZHA 1.2.
Perhaps it used to be ZHA1.2, and now is Zigbee 3.0. (I'm guessing here.)
Until I know more conclusively, I hereby retract my earlier comment about this device being ZHA1.2.

Sorry, I wasn't intending that to be argumentative, but I've been wondering about those units as long as the 1.2 vs 3.0 vis-à-vis the C-8 series conversation has been going on.
As you say, Jasco's documentation says the 43102 is 3.0, and I just found the CSA listing where both the 43102 (as ZB1001) and the 43132 (as ZB1002) are certified as 3.0. I think we can claim that both are? / could-be? 3.0 units.

Still today, I'm upset with the zigbee compatibility on C8. Many Tuya devices pair nicely on C7 but pair with "no data" on C8. I really would like to have only one hub. What is the real issue on hubitat's C8 chip? Some may say: "those devices don't follow the standard". OK, but C7 talked with them nicely. I don't want that feature/bug on C8.

Although I would enjoy a little more interaction from the Hubitat team on this issue I am not convinced that they can do anything, other than add their expertise. I have read many posts with other platforms, Home Assistant for example, where people have similar issues. One bad actor on your network and it can bring down anyones radio.
Since I have become a pro at moving devices back and forth between C5, C7, C8 and C9-Pro I can definitively say that I have not cracked the issue. I am offloading all of my zigbee onto my C7 now as it just works. I don't know what the downside is of not using the 3.0 radio is - presumably there are some capabilities that I am not away of that I should want to use?
Taking away a lot of aqara door sensors definately made my life easier

To be honest, I had really high hopes for the C8 but it’s been harder to work with than the 5yr old Samsung Smartthings I had. If I could get my money back, I would but it’s too late. Just gotta ride out this hub as I don’t have the money to keep buying tech toys. I tread adding smart devices to this unit.
I will second this. On my C7 hub, I had a couple of Aqara devices which I got working by replacing some older HA 1.2 smartswitches which did not repeat the Aqara signals properly.
The older Aqara did not play nicely with the Zigbee 3.0 radio in the C8. After replacing the Aqara devices with Zigbee 3.0 devices, connections are stable .
There are some Aqara devices that claim to be Zigbee 3.0, but earlier devices are not even fully Zigbee 1.2 compliant.
I wish I could at least run the zigbee stack in a way that it enhanced device compatibility the same way it was on C7 (even with drawbacks, i.e. security) because I feel that old devices with chips running HA1.2 will be around for a long time (the same as WiFi 2.4 band)…
Just FYI, since my c-8 no longer suffers from this: looking at the Zigbee Map App, all but 1 of my devices routes via a Zigbee 3.0 device. 4 Sonoff Zigbee 3.0 dongles, 3 Samsung(Aeotec) Zigbee 3.0 plugs, 1 Hue plug , 1 GE Zigbee 3.0 dimmer, and 1 Tuya relay do all of the routing despite very strong GE Zigbee 1.2 in-wall dimmers scattered around the house. The only device routing via a Zigbee 1.2 is a Kwikset lock. Perhaps there is some sort of difference in how the older devices report their connection strength/status?

The Zigbee 3.0 standard is fully backward compliant with Zigbee 1.2 HA. Thus, any devices that fully comply with the Zigbee 1.2 HA standard should work with the Zigbee 3.0 radio in the C8/C8 Pro.
The problem occurs with devices that are only partially compliant with the Z1.2HA standard. Aqara Zigbee devices were designed to work ONLY with their own hub which was not fully Z1.2HA compliant. With some effort, community members were able to get many of thedevices working with the Z1.2HA radio in the C7, but they were never supported officially. The only hub that officially supports older Aqara devices is the Aqara hub. The problem is not with Hubitat or even Zigbee 3.0, but with Aqara failing to comply with the standard.
Fortunately, Aqara is working with the Connectivity Standards Alliance to develop devices that are compliant with industry standards, but that still does not fix the issue with older devices that are not compliant.

The fact is, as of today, still many "non-compliant ZHA1.2" devices are around us and this is a real issue because C7 offered this compatibility (at least unofficially), so the "fully backward compatible" part is questionable when comparing C7 and C8 hubs...

True. If you have a lot of non-compliant devices the C-7 hub which featured as HA1.2 radio is a better option than the C-8 with a Zigbee 3.0 radio.
I still have my C-7 hub in storage, but I migrated all my devices to the C-8. I only had a couple of non-compliant devices, so I just replaced them with Zigbee 3.0 devices. I realize that this might not be economically feasible for someone with 50 non-compliant devices. For those folks, the C-7 hub is still an option. You can still purchase the C-7 new or you can find someone who has a used C-7 who is willing to part with it. I do not plan on getting rid of my C-7 until I purchase a C-8 Pro, but for now the C-8 works fine.
