Everything quit working last night, just as we went to bed.
Got up this morning and got on the computer and went to open Hubitat. I acts like a whole new hub and wants me to do a setup. I have the "Get Started" screen. Have I lost everything I have done? Where do I go from here?
This could be an indicator for the problem with the ZWave mesh.
My C-7 did this couple times.
All was about few ghost plus few not really compatible devices
(mostly Zooz toys).
There are already few related topics regarding ZWave mesh
stability on C-7 hub(s).
I had this happen on my C7 Hub. When reviewing the logs it showed several references to a database problem. I just restored from backup and everything was up and running again fine. I would also suggest you check for ghost devices as the previous poster mentioned. They seem to wreak havoc on a Zwave mesh
A lot of those issues have been ironed out in the subsequent updates over the last several months. The only Zwave issues I have had have been of my own making. Either placing the hubs on a metal shelf, or not turning energy reporting off and updating the firmware on my zooz double plugs (mainly because I don't need them that badly and don't want to hassle with looking up invoices so I can get the firmware from zooz through their rather arduous verification process.
I just finished my month long fight with ZWave mesh instability.
Everything was OK with the C-5 hub but just switching to the C-7 hub
resulted in few hub crashes and almost 100% dead entire ZWave network.
