This morning I found two updates for my hub were ready to install.
I downloaded a backup, and proceded with the update.
After about five minutes the update page sayed that the hub was going to restart.
Never came back online :frowning:

I checked to see if I could connect to the diagnostics update, but it to was dead.
Checked the physical hub, and there was a blue light, intermitted: ten seconds bue, two seconds off (rinds and repeat)
Took the power off for 30 minutes, but after re-powering the hub the same issue.

I my hub dead again?
(did create a ticket with Hubitat)

Hmm, The hub is live again?!
Why would it take almost 3 hours to start the hub?

The hub is connected to a dedicated UPS. When I inspect the stats page of the UPS, it seems rock stable.

I do not use the native adapter, UPS strait to the HUB.

Press the reset button on the bottom of the hub with a paperclip to clear the network settings and see how that fares. Your database could also be corrupt.

But would a corrupt database also disable a simple ping to the device?
The MAC adress of the hup is not found on my network (and yeah, I did check the cable)

It could stall on bootup but unlikely. I would try the reset button, and if it comes back even 3 hours later, do a soft reset and restore from the database you downloaded to your pc. Also what color is the led?

11

Blue for ten seconds, off for two seconds, and this pattern repeats endlessly.

12

This is what bothers me. Almost sounds like a bootloader error, but depending on what happens at the 10 second mark it could very well be a database corruption issue.

Please send me a PM along with your hub's MAC or hub id. I would also take the hub out of UPS for the moment to eliminate the possibility of power failure caused by UPS. In rare cases it could be a software issue with how the hub is starting up, but more often than not, blinking blue light is 99.9% related to power failure.

Took the power off for 15 minutes > same issue
Took the power of again for 30 minutes > it boots?!
Did a soft reset & restore DB backup.

Lets see when I do a reboot if it has the same behavior..

Great that you got it back up and working but this.......

.....would be something I would want to eliminate.

Don't just unplug it though, that is what leads to corrupt databases (unclean shutdown) use settings menu to reboot

Also have you upgraded your z-wave stack?

18

I only unplug if the hub is not back up after half an hour of a normal reboot.
And yeah, the z-wave stack was updated when it came to Hubitat.
