Unexpected hub reboots

I have had a few unexpected reboots recently (latest being today) and I can't pin down what could be causing this. Admittedly, it's only recently that I have put an alert when HE restarts so it could be that I am only noticing this now. I was wondering if anyone else has had this issue? Firmware is 2.2.5.131, C-5. Hub is plugged into a UPS.

I have added a few devices, both Zigbee and Z-Wave (Xiaomi Light Sensor, Ecolink Tilt Sensor, Ecolink Contact Sensor, Sengled Contact Sensor) over the past few weeks and apart from the Xiaomi Light Sensor, they are using built-in drivers. Logs look clean with no errors for as long as the logs go back (about 1 week).

All devices come up fine and are responding, but I was wondering if I should be concerned.

Anything unexpected is not good.

Could be momentary power loss causing it to reboot. Consider using a different micro-usb cable and a/c adapter to check.

I have it plugged into a UPS, so unlikely that it's a power glitch

I mean the usb cord, or the a/c adapter could be defective.

Doesn’t matter if your UPS has mains or battery power if something’s wrong electrically in between the outlet on your UPS and the micro-usb port on the hub.

Yeah - but logs are clean so not sure where to start looking. :man_shrugging:t2:

Ah - sorry. Will try a different adapter (need to find one)...

Random reboots without anything in the logs, or any other behavior like a hub slowdown or freeze, just smells like a power issue to me.

Mind me asking how did you set up the notification? I haven't seen a C5 or a C7 doing that and is very rare when it happens on a C4.

I know you didn’t ask me, but I use rule machine :wink:.

I use Node-red to send an SMS when it sees a "systemStart" event.

Ok, thanks. I can see frequent cloud disconnects but also some frequent hub reboots too. I have escalated your case to engineering to have it looked in more details. Will PM when I hear back.

Looks like @bobbyD knows something I don’t. As usual. :upside_down_face:

On the Feb 27, I was testing the notification, so there were/are at least 3 restarts. Other than that, my scheduled reboots are on Saturday at 7:00 AM. Thanks for escalating - please let me know if you need any other info.

Why scheduled reboots?

From the 27th, you had 2 full reboots, one today and one on the 28th. However, you had several cloud disconnects only today. Are the two reboots legit? And how many notifications did you get?

17

Hmm - 28th was a Sunday, so not legit and today's is definitely not legit. I'm wondering if the cloud disconnects are because I've been noticing that my fiber connection "blips" - goes out for between 1 -3 minutes a couple of times a day. For example - I noticed that it went out about 20-25 minutes ago (about 6:10 PM US Central).

EDIT: I received notifications on both days.

Yup, that would do it. But I don't know if there is a correlation between these blips and reboots. That is what needs to be investigated.

Unfortunately, the outages are so short that I can't really identify when they happen (unless I'm looking at the modem or if I happen to be on the internet at the same time). I did try setting up a monitoring service to see how often it was happening but I would need to do this every 5 seconds or so!

I don't know if this is a "thing" still, but early on there was a whole bunch of noise around slowdowns. Reasonably sure it's not required any longer but figured there was no harm.
