I hope my perilous journey into z-wave tables can help you
I have 35+ Z-wave devices and LOTS of Z-Virtual stuff. The more you have, the longer it takes btw.
Z-wave repair in new app attempted 6-9 times and after over an hour per time with wheel spinning I can say with absolute certainty that nothing was repaired and lots of time was wasted but hey, my wife was happy that I was untethered so the kids got more quality Dad time.
I’ve gotten classic to succeed a few times and tested out the success by moving repeaters, unplugging devices and such just to verify that it wasn’t a superficial repair. The classic repair usually takes me about 8-15 minutes. Lately it is hit and miss when it wants to work and like others have said, maybe its due to the phasing out.
IDE repair has been the workhorse and seems to be the best chance at repairs but I have found a few things to make it go smoother. It seems unnecessary to do this and many would think I’m silly but I turn ON all my Z-wave devices, lights and all and then run it from IDE and 100% success. Maybe I’ve been lucky and this is a ritual that is as unnecessary as not washing my underwear but its easy to do and doesn’t smell bad
If going through IDE, you just have to remember the order of operations
“My Locations”–>Select Location–>Click on your “ACTIVE” Hub–>“View Utilities”–>“Repair Z-Wave network” and you should be good.
