At my wits end here. On random nights, and only at night, my hub freezes - I can’t access via the app or webpage, I need to physically unplug it. The log is giving me nothing … just regular activities and then nothing. Doesn’t seem like it’s the exact same time every night from what I can tell, nor does there seem to be a common event/device that precedes the freeze.
I just see something like this;
[dev:1805]2023-10-01 07:44:39.087 AM[info]route info- Destination:This Hub, Next Hop:This Hub, Status:Inactive
[dev:1751]2023-10-01 03:59:38.956 AM[info]Master Bath Motion motion became inactive
I’ve removed apps, turned off as many scheduled activities as I can and no change.
I don’t have any unifi stuff. My network is an Eero mesh, in bridge mode. All nodes other than one are hardwired, as is my HE hub. Wi-Fi is also set up and enabled on the HE hub. Most network devices, including the HE hub have an assigned IP address in a reserved range. My router is a TP link, that provides all network network services, nothing from my ISP. My HE hub is updated to the latest public release. I was actually forced to do a soft reset last week as I had a power outage and the database was corrupted but this problem was happening prior to that so I don’t think it’s the cause. Certainly able to do that again if necessary. Not sure about jumbo frames, but given the time that it’s happening I don’t think network congestion could be the issue?
I also turned off the automated backups as I did notice those were scheduled at around the same time - or at least at night.
As for getting to the hub, it’s unresponsive via the IP address, and that includes diagnostic mode. Admittedly when it’s happening I don’t have a lot of time to troubleshoot as the dogs need to go out and HSM is presumably armed.
One thing that I found on another thread is perhaps Zwave ghost devices? I did do a migration from C7 to C8 in the last six months, and also moved houses where I could potentially see Zwave devices that are not currently active. But not sure how to track those down. If I look at the graph there’s nothing that seems to be on its own. I’ve done a repair multiple times.
Will do, but limited to my iPad ATM. I’m seeing some entries like the below … no name, no routing. I have 3 sirens, but they’re all listed elsewhere in the table - so this seems to be a ghost? Doesn’t seem to want to be removed …
The one with discover next to it is a ghost. Click refresh and then remove. It may take a couple of tries. I could not imagine working off of an ipad or a phone to do this. Using a pc makes life so much easier.
It is pretty unlikely one ghost node is causing the entire hub to lock up?
Yes that is safe. There is also a chance it is a client if you have any NAS devices or servers it is possible they have Jumbo Frames enabled. Especially on a NAS it is a popular setting. There was a case where a NAS/Server was doing some sort of overnight maintenance or backup and that was causing the hub to go offline, probably due to some sort of multicast jumbo frames. I think they either segregated that device or found how to turn off the JF.
I thought of one other thing as well, do you have the hub hard wired directly to the router or into one of the mesh nodes? I know that has come up before and was possibly causing some problems. I know for sure the Eero mesh has come up multiple times with people having issues, might be worth a search on the forums.
@derek1 did you get this issue resolved? If so, what was the solution?
I started having similar issue... hub freeze every 1-2 day overnight. Also use eero routers. Not sure where to start troubleshooting. Any ideas are greatly appreciated. Thanks!
I seem to have. After a couple suggestions from some community members I looked into my Zwave tables and found quite a few ghost devices. I’ve moved, upgraded and there were just these remnants left that I couldn’t get rid of. I ended up resetting my Zwave radio and repairing everything very carefully. Fingers crossed I haven’t had an unexplained lock up since.
