Broken Hub Mesh

After I did the restore from my 17 month old backup it still did not see the hubs. So here are the additional steps that I just did.

  1. Soft Reset
  2. Reboot
  3. Changed Hub Names and LAN Names (All different)
  4. Rebooted
  5. Reverted to 2.3.6.136
  6. Rebooted
  7. Enabled Hub Mesh
  8. Rebooted
  9. Checked if meshed hubs appear (No they are not)
  10. Restored from backups for 12/2022 (No significant changes from backup until failures)
  11. Rebooted
  12. Checked if meshed hubs appear (No they are not)
  13. Unplugged after shutdown Hub 1 for 10 Minutes
  14. Booted Hub 1
  15. Unplugged after shutdown Hub 2 for 10 Minutes
  16. Booted Hub 2
  17. Checked if meshed hubs appear (No they are not)
  18. Currently allowing Hubs to sit and hopefully locate one another
    18a) Will allow them to sit for a couple of hours.
  19. After this is done I will move both of the hubs to the same network switch and within 1 foot from each other. (currently both Hubs are about 15 feet away, All switches are managed switches HP enterprise Procurves)

As an Additional step, I may go ahead and change the IP Addresses to something other than what they have been set to.

As I stated, I might be misremembering, but why donโ€™t you share a device from each hub and see if the meshed hubs โ€œlinkupโ€? I will bow out now. Good luck.

I have multiple devices shared on both hubs, they are still not displaying the hubs in the Hub Mesh settings.

I think the 1 foot thing is unnecessary, Hubmesh doesn't rely on its own network, it relies on existing ethernet or Wifi. If the hub can communicate to the router, it should be fine.

What I do think is that your network somehow is blocking something or not playing nice for some reason. I do think moving both hubs to the same switch as a test would be prudent. If you had a dumb or unmanaged switch, this would be even better.

My opinion, but unless you are an IT pro, this device is probably overkill. I would be curious to know why a home user needs something like this? I have seen a few users in the past few weeks proudly proclaim they have enterprise equipment, and I am truly baffled why that is desirable, nor necessary.

That said, maybe if you give your router brand/model, someone will know if there is a known issue with that device. I am theorizing that something is misconfigured in router settings, or some update (or fallback to default) on the router has caused a change in behavior.

As previously stated. Everything was working as it should before the power outage. All required servers are on UPS's which these servers pass all network required services. All of the servers where functioning properly and stayed running while power was out.

I know making statements that this unit may cause an issue or that LAN device may cause this. However, the only thing that has changed is that the hubs are not linked in the mesh. I am assuming that the problem is with either the configuration files on the Hubs and not with the network, as nothing has been disrupted configuration wise.

I have 3 HD Home Runs and these did not have issues connecting to their server. I know that these are two different device types however, these use config files on the device side that did not have issues.

I would like to have a Hubitat Team Member reach out so that 1) they can login to my devices and troubleshoot, or 2) Help step me though accessing the device through command line to review probable issues.

I do appreciate the help and suggestions that everyone has given, but this seems to be above everyone's pay grade and expertise.

OK!!!!

As of my last post a few minutes ago. My hubs are now seeing one another. They are showing up in the Hub Mesh section.

Thanks for all the suggestions and attempts to return a solution.

Well, I did want to tell everyone what my last steps were.

After Step 19 from above.

  1. I Changed the IP addresses Via DHCP Server (reserved a completely different IP)
  2. Cleared the ARP Cache
  3. Added the two new IP's to DNS making them static
  4. Shutdown Hub 2 and moved it to where Hub 1 is on the same managed switch.
  5. Booted Hub 2 and watched for any changes in Hub Mesh.
  6. After clicking reconnect on Hub 1, Hub 2 showed up in Hub 1 Hub Mesh connected
  7. After a few more minutes Hub 2 showed Hub 1
  8. Moved Hub 2 back to the original location and Hubs were still showing
  9. Updated Platform version to the latest
  10. After booting back up both Hubs lost all shared and non-shared devices
  11. Restored backup dated 05/25/2024
  12. After reboot, all rules and devices showed, and only needed to click reconnect on hub 1 then everything was good.

OK, So this is extremely irritating. I updated to the most resent version of the platform, now the hub mesh is not working again. What is up with this. I've been working on it for the past hour and a half and nothing works.

Can this please be fixed. I rev-d back to 2.3.9.136 on both hubs but nothing, then restored from a backup from yesterday keeping on the rev-d version, still nothing.

Then I rev-d back to 2.3.7.145 using yesterdays backup, again nothing.

Now I'm on my backup from 12/2022

So I just completed a soft reset, with both the 2.3.7.145 platform rev. and the restore of backup 12/2024. Then the hub mesh connected. Then I updated to 2.3.9.143, then rebooted. Had to do a restore of a backup so I did yesterdays backup. Now it is all broken again. It really looks like something funky with the Platform releases.

Maybe some HE tech can take a look at why this keeps happening.

So finally, I think this issue has been resolved. I have my C5 in a location further away from my C7, so I made a change to my network ports and placed both the C5 and C7 on the same switch. This seems to have resolved the issue. My only question is why for the past year and a half did this use occur when I had no problems with any of my devices or rules? I am however now having issues with all of my basic rules that run with Waits or Modes (see my new post).

There was some recent changes to the mDNS, to prevent a mDNS storm, which I think HubMesh uses in part. Possibly side effects from that change.

The basic rules issue is a known issue and will be fixed in the next release. There are at least a dozen posts about it on here already.
