I have had a problem from the beginning with my Hubitat disconnecting from my home network. It was frequent then seemed like it got a little better, but now I’m back to it disconnecting multiple times a week. The only way I can get it to reconnect is to power cycle the hub, rebooting my home network does nothing to get the hub back online.
I have an eero setup, the hub is on WiFi, not Ethernet I don’t have that option due to placement of devices, and eero network and hubitat are on the latest available versions.
Watching this for answers. I had the same issue with my C8 hub. I have moved the hub to a location where I can plug it into Ethernet but it is not where I would really like the hub to be.
I was doing some testing with my extra C8 hub not long ago on my Unifi gear. What i found was it seemed to have issues mostly when the network would drop it. It seemed to happen when i would load firmware to the AP it was connected to and then reboot it. Is there any chance your gear is going offline and coming back online frequently.
How is the hub powered? Are you using the included power adapter.
I do think that is an issue, as I have noticed it in close proximity to a network firmware update, but it is way more frequent than that. So it could happen when a network update happens, but that’s not the only time it happens.
When my network reboots, all other devices come back too, it’s just the hubitat that refuses to come back online.
Yeas I am using the supplied power adapter as well
Well network firmware update was just how i induced the condition. The point was if the APit was connected to goes completely offline then it wouldn't reconnect. By chance could your network be going offline. Maybe this is a 802.11r roaming issue where it doesn't want to roam gracefully.
I also thought a firmware update for hubitat fixed this so what firmware are you on.
What hub platform/firmware version are you running?
If you have multiple APs, manually lock it to the one you want it to be on. I think most mesh systems allow you to do this? This would prevent the mesh from trying to coerce it to move to another node.
Also, check if you have any sort of wifi optimization which may automatically change the Wifi channels on the nodes. This was known in the past to knock HE offline.
FWIW, I can reboot my router and my Dev C8 came back online very quickly.
Do your 2.4 GHz and 5 GHz networks have the same SSIDs?
Your hub may disconnect from the 2.4GHz network for any number of reasons, but instead of reconnecting immediately back to the 2.4 network, it tries to negotiate a connection with the 5 GHz network, which won't be successful.
I guess I didn't think that one through long enough.
If the hub doesn't have a 5 GHz receiver, it wouldn't even be aware of the 5G signal, even if was the same SSID the hub was looking for.
I personally like to have different SSIDs on each radio band to prevent issues I have experienced in the past, but as you said, that wouldn't be causing a problem in this case.
