21 are paired with a C-8 hub (in use daily) and the other 9 are for Christmas (paired to a C-7 hub).
I'm having issues with the ones on the C-8. I've been fighting this for a while and I'm not sure what caused it but occasionally one outlet will randomly stop working. One of a few things may be true when this happens:
A rule fires to control an outlet, the command is sent, but nothing happens. Sending the command again manually works.

I have played with changing the Zigbee frequency to no effect. I don't see anything wrong with the mesh (plenty of communication on the device graph) but I may be overlooking the obvious, not sure.
My 2.4GHz Wi-Fi is channel 6 and my Zigbee is on Channel 14. I know that's close but would that cause this?
My C-7 is on Zigbee channel 16 (which does overlap) and oddly enough, I'm having no trouble with it.
I should also mention that I have shut down the hub and let it stay off for hours (hoping it would rebuild the mesh) and that hasn't helped. I have also gone around and unplugged and replugged all of the outlets, thinking maybe one wasn't playing nice, but that didn't help either.
I've had it on 25 previously. The hub shows something else occupying 25 (no idea what) and I was having more issues when it was on 25, thus the switch back to 14.
I have a C-7 and a SmartThings in addition to the C-8 that I’m having trouble with. None of those are on 25 but when I scan I see two entries on that channel and I had worse trouble on 25 in previous attempts.
26 is forced by the FCC to use a low power setting. Thus, it is typically not recommended.
Why not use Zigbee channel 15? It is typically in the clear, as long as your 2.4GHz WiFi is using only channels 1, 6, and/or 11 with a 20MHz channel width.
Will try that next. I changed to 23 this morning and I also changed my 2.4GHz to Channel 1. Also found it was using 20MHz and 40MHz so limited it to 20 only. Will give it a day or two to sort itself out and then see how it goes.
I'm still having occasional issues but they're really weird. Gonna try Zigbee 15 next but is this really a channel issue? Take a look at this:
I have a rule that fires at night when both of my kids have gone to bed to turn off the living room lamp right outside their doors. One of the triggers is one of their doors closing. Last night, I closed my daughter's door and the lamp didn't turn off. So I opened the door and closed it again. Still nothing.
I opened my app to see if the hub knew both doors were shut. It did. So I sent the off command to the switch from the dashboard and it worked flawlessly.
See screenshot below. I also included a couple of other rules that fired that sent commands but weren't responded to. The end result was the switch was on but it wouldn't turn off via rule.
The full channel scan on the hub also comes back blank most of the time. I'm just noticing this as I wanted to verify 15 is unoccupied before switching to it. It was doing similar before I made the change to 23.
So I changed to 15 because 23 didn't solve my issues. Doesn't seem 15 is going to either. I thought it had (it was working quite well - fast and no non-responsive devices) but I came home today to find a lamp not on that should've come on. I can see the command sent but no change in status. I turned it on manually and it did turn on but it was slow.
I have also been having trouble with a Centralite Keypad that is mere feet from the hub dropping off quite frequently. I had thought it may be this device, given the plugs had been working so well, but I don't believe that to be the case now with the issues with the plugs coming back.
I'm on Wifi Channel 1, 20MHz only (40 is turned off).
Working backwards, is it the automation that is failing, or the device/radio?
If you try the device from the device settings page, with logging turned on, do the outlets consistently turn on and off? Do the logs reflect the physical condition of the outlets?
The one thing that seems odd is the keypad also failing, which would point to some radio issue, whether hardware or otherwise.
I would PM bobbyD and see if there is anything in the engineering logs that point to what is going on.
They do for a long time and then just randomly stop. What’s funny is the keypad is back to working consistently and now a few plugs and a button have started acting up. I actually bought another button last night because I thought this one was dead. Today, working fine.
At this point I do wonder if it’s the radio. I sent a PM to BobbyD but haven’t heard back.
I must be on Hubitat’s naughty list as I also sent an email about my Hub Protect subscription and haven’t heard back on that yet either.
I bet they are bogged down with the heavy Black Friday sales volume. I suspect it will take him a few days to get back to you.
Hubitat doesn't have an email. I am not sure where, or to who you sent an email, but as far as I know they haven't used email for support for many years now.
I think I may have more evidence of this, @neonturbo. I got home today to find the Zigbee network was offline. I just shut down the hub and will bring it back up and suspect it will be fine, but I do think something is up.
@bobbyD - sent a PM to you a while back but I imagine you get a lot that maybe you don't get to see them all so thought I'd ping you here as well in case it helps. Would you be able to look at the engineering logs on my hub for me please to determine if something is going on?
If it's fine, then is not the radio. It would likely be the radio if it stays offline. Centralite outlets can get quite chatty, which may overwhelm the radio at times, though devices wouldn't drop of the mesh. That is more indicative of severe interference.
