C-8 hub not responding

🛎️ Get Help Devices

Hi there,

My C-8 hub suddenly started flashing green and red about a month ago. From reading on here I can see that the flashing lights would usually suggest that there's a connection error?

I've finally had a bit of time today to try to sort it.

I followed the suggestions in the Support section, i.e. I've hit the reset button underneath for 7 seconds. Once it rebooted then it went back to flashing red and green.

I then thought I should rule out the fact that there is a genuine connection error. I therefore plugged my old C-7 hub into the exact same ethernet cable and that worked first time.

I can't see the C-8 hub listed as a device on my router and I also can't connect via MAC address. Am therefore out of suggestions.

Can anyone help?

Disable wifi on the hub.

Hi Rick, how would I do that if the hub isn't responding? Is there a physical way of disabling that?

Sorry misread the original post. If you cannot get to it, Switch to a different port on your router or switch and change cable regardless if the c7 works or not. If that still doesn't work then you should put in a warranty request at support.hubitat.com

Can you try to reset the network again, but holding the hidden button longer?

Hi, I did try this several times (10+ seconds). The hub is clearly resetting as the light turns blue for a couple of minutes while booting up. However, it then goes back to the red and green flashing lights. I've now tried a few different ethernet ports with a few different cables that are connected to things that are working absolutely fine and the issue is clearly the hub. It's not yet 4 months old, so presumably my best bet at this stage is to request a refund from the retailer (Vesternet in the UK)? It failed a month ago, so feasibly that was only about 10 weeks after purchase...

Thanks,

Ben

You're not using a poe splitter are you? Also have you tried swapping power supplies? (your phone charger should work)

No, just straight into the router. I don't use PoE. Have also tried 3 different USB-C chargers, just to rule that out as well.

Just curious. Do you have another switch or an old test router you can plug it into? I mean if needed just take it to a friend's house and see if it connects properly there...

I don't, but am at a friend's house for the weekend so will take it with me to see what happens when plugged in there.

Just tried this and confirmed it's still flashing green and red at a friend's house, even after resetting it again. Shall I fill out a warranty request? What is the reason for the form?

Yes go to Warranty – Hubitat Support and the @support_team will take care of you. At this point the blinking means no connection via the lan so the hub seems to have failed. You've tried different switches and the network reset button. I think you're out of options here. You could try setting it up on wifi to obtain a current backup unless you have hub protect then it's in the cloud and you don't need to worry about that.

You can use "Hub has a blue light" option. You will need to use the following form as you've purchased the hub from one of our partners:

Any ideas how long these claims take? I filled out the warranty reseller form 2-3 weeks ago, but don't appear to have heard back.

We have authorized your replacement on August 16th. Have you not heard back from reseller or you didn't receive our email?

For the past few weeks, my C-8 has been showing signs of not being responsive. Happened again just now; no flashing lights, dashboard weren't responding so I power cycled the unit. Not sure what's happening but this would be the 3rd time in the past 2 months. My C-7 was a tank.

Did you try going to yourhubip:8081 ?
What do your logs say (both regular and event) at the time of the lockup(s)
What lan integrations do you have (kasa is always suspect)
What does your z-wave details page look like?

Hi BobbyD, I didn't receive an email from either Hubitat or the reseller (Vesternet in the UK). Is it possible to re-send? Keen to get everything set up again.

Thanks

Sorry is it possible to come back to me on this? At this stage is it just easier to buy a replacement and I can be refunded the original purchase? I've been waiting 6 weeks already, so really need to get this replaced asap so my devices work.
