Have a new C7 HE. Installed 25 old (non Plus) devices and everything was working pretty well. I decided to add/replace about 8 Plus devices to strengthen my mesh. It has been horrible! My previously pretty good network now has numerous problems, and I can't communicate with several devices that were previously just fine.
After installing the new devices, I waited for 4 hours and ran a Z-wave Repair. It now shows that a device (non Plus) that is literally 8 feet away from the HE, separated by a hollow wood door, is using 4 hops to get back to the HE, and I am unable to turn that device on or off.
Routes automatically update for the plus devices but non-plus only update when the route fails or you run a repair. When you do your repairs start from the hub out. You can leave the plus devices alone and let them find their own path. Assuming when you removed the devices you didn't leave any nodes in there with failed joins it should sort it's self out over a couple of days.
Given the symptoms though I suspect there may be a failed pair in there. Go to settings, zwave details and look in the clusters column. Do you have any devices with nothing in the clusters column besides the first one which is the hub radio? A screenshot would help with troubleshooting. How many devices do you have and how many square feet is the house?
The new C7 hub nearly matches Zigbee self-healing capabilities. Running repair on an unhealthy mesh does more harm than good. It is better to let the radio handle the routing while trying to identify and remove the bad nodes. If a node is moved around, individual node repair is a better choice. Time is the best healer, like you suggested.
I just unwittingly did an experiment by turning off the basement lights breaker yesterday. This morning an automation on the first floor didn't work. After trying a few times, it started up. Not sure why it originally routed to the switches downstairs, but its working well now.
Anyway, with a bunch of z+ wall switches, powering off breakers could be a way to shake things up some, if that was desired.
The "self-healing power" is only true for C7, running Z-Wave repair on an unhealthy mesh is ineffective for any controller. If repair fails the issue must be addressed before running another repair.
Yes, I did have 2 failed devices showing in the Z-Wave screen. But it has been difficult to "remove" them. Finally, just got it done.
I have 30 Z-wave devices in a 2200 square foot home. FYI. Most of the new Plus devices are Zooz Zen26 switches and Zen27 dimmers. Everything was working pretty well until I installed these switches. I contacted Hubitat Support about problems with new Plus devices not setting up properly (wrong device Type) and they responded that they will be fixed in the next firmware release, due next Monday.
Update: After finally getting the last phantom device removed, I also moved the HE hub. The hub was located on top of my metal alarm box (4" x 12" surface). I moved the hub about 1 foot directly above that box. Rebooted. Ran a Z-wave Repair and things look much better now. Most of my devices now have a single hop. The worst devices are 3 hops. Still don't understand the Z-wave screen in HE. A couple of devices show no Routing information, but seem to work just fine.??? Think I will attempt to just let the network run for a few days, now.
Are you saying that rather than running the "Z-wave Repair" at the top of the screen, I should hit the "repair" button for each (non plus) device listed in the table? I have done that a few times and it does not seem to do much.
