So why did my Z-Wave network crap out for no reason???
Nothing changed. I did nothing. All of the firmware updated or not was working just fine.
I don't want to spend the weekend resetting everything and using a laptop and Z-Wave stick to update firmware again.
I'm just taking a punt here but maybe one of your devices that may be repeating has gone faulty and is causing the issues.
Could you maybe power down your devices and bring them in one by one to see if this is the issue.
Like I say, just thinking aloud of something that might be worth trying.
Just another thought. Maybe the z-wave page will show a common device in all the devices that have failed.
Not saying this is what you’re seeing, but I have seen on occasion a device (or more?) go crazy and start blasting its radio, resulting in a lot of issues within my Z-Wave network (and the Z-Wave of my security system).
To resolve this, I shut down the house power and turned it back on (while ensuring my Hub and anything else critical was on UPS...). This quickly solved the problem but unfortunately didn’t allow me to figure out the root cause...
One Z-Wave device going south can take the entire Z-Wave mesh with it.
What's your Z-Wave Details page look like - any devices showing missing routing, or missing Clusters? Or sporting a Failed message and Remove button?
This same issue on my C7 happened to me one morning and my hair (what's remaining) completely fell out.
I shutdown the C7, powered it off for 20 sec, powered it back on, and all network mesh came back....
Whew!
Good point - I just noticed @Hal3 didn't mention trying reboot or a shutdown.
What’s on your Z-Wave network? No way to answer why something might have happened if all the information we have is that it happened.
I powered down the hub and unplugged it from the power for a few minutes and started it back up.
I'm going to leave the Z-Wave network alone overnight and see where it is in the morning.
Thanks for the comments and suggestions!
I guess I’d also ask what does “crapped out” mean in this context? Your screenshot is just of a zwave repair having some failures, are there devices that aren’t functioning/responding as you expect? I’d note that failures to repair isn’t necessarily a good indicator and really it’s a question of whether devices are responding.
It’s possible you have devices that aren’t responding anymore, but there aren’t enough details in your post to give most folks a direction to give you specific advice, past what they have already said.
One Zooz ZEN30 stopped controlling the light either remotely or at the paddles but still controls the fan. A second Zooz ZEN30 just stopped communicating but works at the paddles for both light and fan. I tried the air gap thing etc. but I can't even get the ZEN30s to go into pairing mode.
Funday Sunday!
Stringing Ethernet cable through the house so I can run Hubitat five feet away from the first malfunctioning Zooz ZEN30.
I confirmed exclusion and attempted to re-discover. Now it is stuck on initializing for 30 minutes.
At what point do I just start pulling the malfunctioning Zooz products and sending them back?
"Fixing" the same Zooz switch or dimmer repeatedly when nothing has changed is unacceptable.
Finally got one ZEN30 working like it did Friday. Multiple resets, retrys, reboots, air gap pulls, stringing Ethernet cable through the house and two hours. 
I might as well try to update the ZEN30 firmware while I have the hub nearby.
FW updates w/Zooz devices often do include fixes for issues.
Adding @erktrek, who has a lot of experience w/Zooz.
The c7 still has some z-wave issues to be worked out. Do you have another z-wave hub you could test out the zen30 on?
Like st, vera or wink?
I have my old Smartthings hub but resurrecting that system is not an appealing project.
If the problem is a Hubitat issue maybe it will get resolved pretty soon.
Oh, well .......
Oh man I wish I had better advice to give.. I've gone through that with Zen23/24s (Toggle Switches).. usually it's a weak mesh thing. My solution was to add in a bunch of repeaters regardless of the powered switches all around. This actually seemed to help.. The other thing I did was use a Z-Stick+ to exclude each several times before attempting a repair an include. I did NOT try including with the Z-Stick+ but I understand that too is a possibility (can only be done with "no security") - would save schlepping an overlong ethernet cable everywhere. I also found that following the instructions for "exclude" also seemed to work for including, for the Zen23/24s at least.
Two of three iBlinds failed to open this morning and seem unresponsive. This is after spending many hours getting them working initially and changing nothing.
I was originally going to set up my Raspberry Pi 4 with Home Assistant before I found out about Hubitat.
There was so much ballyhoo about the HE7 I ordered one instead.
Big mistake!
I cannot keep fixing things that just won't stay fixed or keep finding new ways to fail.
Thank you all for your help along the way.
Let us know how it goes with your migration to Home Assistant. We are here to help if you decide to come back.
I don't envy that move what with the config quirkiness and all.. but the total control aspect along with the GUI stuff definitely has its appeal.
I'm still on team HE though - for my use-case (and my residential client's) it just can't be beat.
