Hub not working after power failure

After a power outage C-7 hub won't connect. The LED is green but nothing is working.

May have jumped IP addresses - particularly if the router took a hit also. Might try http://hubitat.local to see if it responds.


No dice. Router is still working fine, and both are plugged into a UPS so I don't understand how the C-7 died. IP is reserved by the router.

Try rebooting the router - should force it to re-authorize all IPs.

That didn't help either. I have Hub Protect. Where do I make a claim?

Let's try a network reset on the hub. On the bottom of the hub there is one round hole that contains a network reset button, take a paperclip and press that for about 7-10 seconds.


Tried that, light went blue, then back to green. But still nothing. Router shows it offline still.

Running out of rabbits in my hat, so let's see if @support_team has any ideas.

Thanks for your help!

Hub started working on its own. Oh, well.


We've got your warranty case and checked on your hub. It appears that the hub is online and connected to the cloud.

I think someone had an issue with general UPS and Hubitat in that there was a voltage/amp etc drop as the UPS kicked in and that was enough to cause problems with the hub - was in a thread about making up a DIY micro battery based UPS if I remember right.

Might be one of the reasons the really ancient disk sets (think a massive record player) and older raid arrays as well as other hardware would die not long after a power loss.

He did solve it if I remember but with a lot of testing gear and mucking about.

Luckily here we have a stable grid, at least until #Brexitstan really kicks in (or too many Muskkretinwagen being charged at the same time). I can't remember when we last lost power here.
