Connect WiFi hub blinking red

I noticed yesterday that my ST Connect Hub was not accessible from the Connect app on my iPhone. It said it was offline. Last time I used the app was a couple of days ago. I went over to the hub and it’s blinking red. I power-cycled it, and that didn’t help. I then reset it, which caused it to go through a long cycle of various LED colors- red, green blue, yellow, solid, blink… lather rinse and repeat. After about 5-7 min it resumed blinking red.

Oddly enough, local routines are working, but I’m frozen out of accessing it, so I cannot add some new devices.

Any ideas how to recover, or is my ST hub dead? I have a spare Connect Hub, but I’m loath to replace it because I have over 40 connected devices. I also have an old v1 hub, which I assume is or will be soon obsolete/unsupported. Any suggestions, with recovery of existing hub being the highest priority?


I believe the red blinking on the connect hub is a power issue. You may want to contact ST support. Try using the power cord from tHe spare to see if that has any effect.

Thanks. I went ahead and swapped the power supply, but still blinking red. It was (and is) executing local routines such as motion-activated lights and door switches for lights, so I didn’t think the power was the issue.

I don’t know if it is recoverable… I hope it is, but my hopes are dim.

Flashing red on the WiFi hub isn’t a power issue

Check that the hub’s connection to your ISP is good, maybe reboot your cable/dsl/whatever device upstream from the hub.

does that apply for the Connect hub as well or only the newer wifi hub?

You’ll get a red blinking LED if you’ve plugged an Ethernet cable into the output side of the hub when it should have been plugged into the input.

Probably yes. Support page just says “function error”

The Ethernet cable is not plugged into the Output. This was a fully functioning hub. Nothing changed. It just started blinking red.

I’m going to replace it with my spare hub- a total PITA. Sorting thru how to somehow start over. I cannot remove the malfunctioning hub from the Connect app. It tries to add it as a 2nd hub.

I’ll have to then reset some 40 devices, about 1/3 Z-wave. Not fun.

It’s waiting to be set up. Get the app, and add the hub. Once that’s done the light will turn green.

It’s fixed. I know how to install the hubs, but we had had a power surge by PGE a couple of days prior and apparently it damaged an ethernet router between my cable modem and the hub. I replaced that and was able to recover the hub, though not before I had completely reset it first. I had to re-pair all my devices and recreate all my automations.
