All my Zwave devices stopped working and couldn't be found via a repair.
I tried a soft reset which didn't help. I removed devices after the refresh couldn't find them and I attempted to re-add them. I go to zwave inclusion and start it, then put the switch in inclusion mode but I am having no luck.
Did you try a general exclusion? Settings > Z-Wave Details can do this too.
A factory reset of the device clears this data in most cases, too, but there are some oddballs.
Also, make sure your region didn't change (probably US LR if you're in the US or wherever you're actually located if not).
How did you remove the devices? From the device list? You may very well have trashed your mesh. At this point I would actually reset the z-wave radio itself (not anything else) and then factory reset the devices then start pairing. If you have a failed pairing, stop what you are doing, go to the z-wave details page and remove any ghosts created then try again.
Go to yourhubip:8081 from a web browser, under advanced options... That will reset your z-wave radio. Factory reset your device, then start pairing. If you have a faile pairing. Stop! Go to your z-wave details page, remove the ghost device, fatcory reset the device then attempt pairing again.
