C8 ProFreezes upon alert for new update

[chad.m.shearer]

C8 Pro (v 2.4.0.146) Freezes whenever I receive an alert that a new update is available. Happens every single alert, no exceptions.

Any apps that are running fail to complete. No new apps will initiate. It's as is a pause button was used on the Hub.

I've found similar posts, all closed after a tech looked closer. I'm very new, not very savvy. I'm not sure what to look for.

Is your hub hardwired or connected via WiFi?

It looks like the support site redirects to this community forum when I click the link to ask a question there.

Scroll down on that page until you see the "Warranty" section, click on that.

See these two posts (linked below) from the most recent claim of the same nature.

How certain are you that it stops exactly when the updates come out? Or is just that the automations stop working so you log into the hub and there happens to be an update waiting?

By your logic it would have stopped precisely on these dates when updates came out:
12/23/24 (2.4.0.142)
12/24/24 (2.4.0.143)
12/26/24 (.144)
12/31/24 (.145)
1/06/25 (.146)

What do logs show for those dates?

C-8 stops doing automation when new update detected

Over the years, there have been a few similar claims. Staff are very adamant that there is no way this can happen due to the underlying hub software vs the update software, they are entirely different processes. I believe the update check is just that, it doesn't do anything other than ping periodically (daily?) for an update, and when available simply turns on that indicator. Also, there is no setting you (or anyone that I am aware of) can set to prevent checking for updates. Also, hub updat…

C-8 stops doing automation when new update detected

Likely this, especially is user does not go into the UI very often. Automations not working so go to check it out, hmmm hub has an update every time this happens. If you only check every 30 days there is a high chance there WILL be an update waiting for you, especially with 2.3.9 and now 2.4.0 because they were already working on 2.4.0 while still patching 2.3.9 so there was not much time between the final 2.3.9 and the 2.4.0 release. Then if you do update at that point, it reboots the hub, wh…

Here is one thread I could dig up with staff looking into someone's hub doing this. (read the rest of the thread for reference)

Hubitat C4 freezes whenever a new software update is available

I concur.

And another:

Everything Stops When Update Available

Not expected and to be honest, it's pure coincidence that your hub stops working when an update is available. There is no possible correlation between a pending update and the hub freezing. It is possible that you are dealing with a hardware malfunction or a network issue. Similar hub freezing events have been reported when jumbo frames are enabled in the network, for example. Identifying the root cause of your problem requires further investigation. If you'd like, you can send me a private mes…

I remember seeing similar responses from staff in the past, but I didn't dig too deep.

Thank you for your feedback.

I did find those other threads before I submitted this question. One of the recommendations was to delete/truncate the saved logs, so I did that. For that reason I can't go back and look at logs for those days there were updates, but I can confirm that I had a hub freeze every one of those days. I just don't have logs any longer to see those dates.

I do go into the UI frequently as the unit is only a few months old and I'm often making new routines and fine tuning things I've set up. I understand staff have declared it impossible for the update and the hub freeze to be related. I've also seen that the prior submissions received direct support from staff to fix their problem, and nobody ever came back and said "it was fixed by staff and they confirmed it was something else." So I'm trying to state what I can see happening, and looking for the same level of support that fixed the problem for other users.

Thank you for your feedback.

Both of these instances seem to have outside help looking closely to resolve the problem. I also went ahead and truncated the logs, so there is nothing available that far back to look at. The other recommendation provided, to turn off Zigbee radio, I cannot do because I use Zigbee. I did turn off my unused ZWave to see if that would be helpful in a similar way.

@chad.m.shearer

but I can confirm that I had a hub freeze every one of those days.

So then at the end of December the hub was ceasing to run automations nearly every day?

Does it ever have the problem when no updates are available? Like between 12/31 and 1/6, it worked flawless that whole time and then as soon as the .146 update came out all automations stopped working on 1/6 ?

[chad.m.shearer]

Correct. It was like groundhog day, I was astounded. To get automations to run again, my ritual was to install the update and then reboot the hub (at least once, sometimes more) to get it responding again.

It does not have this problem any other time. I did have some devices with spotty connectivity, but I spent time rotating through Zigbee channels to fix that. This is different though, it's a whole hub functionality issue.
