Spontaneous Hub Restart

rakeshg · February 7, 2025, 2:02pm

My C-8 has been stable for quite a while and then I just got an unscheduled hub reboot (I have an alert that is sent when the hub restarts). Not sure what caused it - the logs look clean. Though I did see a "elevated load" alert for a brief moment after the reboot but then it disappeared.

No changes to HE (still on platform 2.3.9.200) recently. I have no rules running in HE (all logic is in Node-RED),

Anything that looks strange in the logs?

Thanks for your help.

Momentary power outage?

My first thought as well.

Not that I could see and I was in the same room but with my back to the hub. Also, we have Tesla whole house backup batteries and the hub is attached to a UPS as well. I checked the KASA activity log (the hub is plugged into a Kasa outlet) and there was nothing there either.

Are you running this on the OEM power block? If so, and it happens again, you may want to try swapping it out for a new one.

Yes I am. Let me see if this happens again and I will try swapping it out for the one on my spare C-7. I also have a couple of C-5s lying around - do you know if they use the same power brick?

IIRC the C-7 and C-5 use the same brick.

Isn't the cable connected permanently to the brick? I think the c8 uses a type C connection vs micro, no?

C8/C8 Pro use the USB-C (Pro needs a stronger block). The Micro-USB connections I believe are all the same output - you may be right on the permanent connections on the OEM brick for the C5, can't remember on the C7 as I may have replaced the power blocks already.

In the first post he said the C8 was restarting, and later was talking about trying a C7 or C5 brick. That's why I mentioned it.

I think the C-8 has a USB-A to USB-C cable. The power adapter looks like it is a USB-A but I can't confirm that without pulling out the cable! The C-7 could be a USB-C (into the hub) but again I can't confirm. The C-5 has a micro USB in, but USB-A from the adapter end, so if needed, I could use that. I have also been using the cable that is for Raspberry Pis (has the on/off button on the cable),

microUSB.
