Broken c7 showing blue light

So, i can see the hub on my router. I can not login to the ip address provided by the find my hub. I can not log into the ip address with :8081 to get to the utility. Both give page not there errors.

To recapitulate:

  1. Your hub has a blue LED when powered.
  2. You are unable to reach port 8081 at the hub's IP address.

For all ostensible purposes, your hub appears to be dead. If your hub is within the warranty period, or, if you purchased an extended warranty plan, you should make a warranty claim at support.hubitat.com

The warranty period for a new hub is 90 days. Used hubs purchased from eBay are unlikely to be within the warranty period.

Based on your posts, a used hub, of uncertain provenance/functionality, purchased from eBay, may also explain the various issues that your hub displayed.

So I did go through a few things via PM already.

  • Has some sort of mesh router with no link lights on the port.
  • Tested the hub on a different old router, link light comes on so thats a start
  • The ethernet cord in the photo I was sent looks questionable @pauljneil2 do you have a different one you can try?
  • findmyhub.hubitat.com thinks it is finding a hub and gives an IP, but cannot connect to web UI or diag tool.

This was my last follow up:

That could be a stale IP from the last time it connected possibly, if you are logged into your account on that page. To know for sure you would have to log into the router and check the devices list, see if there is anything using the IP.

You can also try from a command line (on a PC/Laptop) ping 192.168.10.105 , when the diag tool wont connect that is not likely to work either but worth a try.


Another possibility is that the device you are connecting from is on a different LAN somehow. One way to check that is the IP of the device, it should start the same (192.168.10.xxx). Not sure where to find it exactly on Android, should be in the Wifi settings area somewhere.

Ok, can not ping the hub.

Another obversation, when it is sitting there with the blue light, if i press the reset button forc10 seconds and release, it will go through a series of lights, but it aleays ends at blue and stays there.

I videoed what it does but i can not find a place to add the video. I can describe it though.

Blue light steady
Press reset for 10 seconds
Blue light
green light short
Blue light short
Green light LONG
Red light short
No light LONG
Blue light steady

In the router, it does identify the hub as udhcp 1.26.2

Thanks for the assist everyone.

If your hub has an active connection to your router, what is the IP address for the hub as shown in the router’s admin pages?

You need to confirm if it’s actually still 192.168.10.105 or if another address has been assigned.

That is the normal network reset process. It only resets the networking settings in case people lock themsevles out with bad settings.

Did you verify the IP shown in the router is the same one you are trying to ping / connect to on port 8081? Trust the router more than the findmyhub page.


Also still wanted you to verify this. What is IP of PC/Laptop being used?

In the router, i can see the device but nitvthecip address for the hub, but the ip address for the router is 192.168 10.1 and the ip address of ghe pc is 182.168.10.106

One more thing, it was working for a few days before (after @kkossev helped with the drivers), it crashed and now the reset process that actually changed the lights, but it still goes to the blue light after resetting. Is there another way to reset the hub?

Now i was able to finally see the ip address in the router for the hub. The ip address displayed is 192.168.10.104 for the hub.
Pc 192.168.10.106

So, you were rightthe ip address found with find my hubs does.

When i go to the ip address the hub has, 192.168.10.104 will not load
192.168.10.104:8081 will not load

I can ping 192.168.10.104 without problems.

Any new ideas?

If you can ping it but the diagnostics port won’t load then I don’t know what you can do. It is very rare for the diagnostics tool to crash or not boot. Usually blue light means diagnostics booted but main hub did not boot.

There is no other way to reset or restore it.

Just to confirm, when you ping it from a PC, the MAC address returned from an ARP lookup, matches the MAC address found in "findmyhub" page. Just want to make sure you pinging the proper device.

Also, can you ping continuously, then remove ethernet cable, see the pings drop, and then reconnect, and see the pings succeed again.

If you're really pinging the hub, and have confirmed the proper IP, and have link level connectivity (ping), then the :8081 diag page should work. If not, and you've done a reset, I think it's time for some new HW.

Sorry about that.
