I'm connecting my C7 to my new C8 with Hub Mesh and just could not get the hubs to see each other. Both are using the WiFi option. I know the C7 WiFi is still in Beta so is this the reason why the hubs can't see each other on the same home network?
I put both back on Ethernet and Hub Mesh worked right away. I'm hoping that this is only a temporary issue as I can't keep a 100ft Ethernet cable going to the C7 on my lawn forever.
Maybe I'm missing some extra required configurations to run Hub Mesh over WiFi? If not I'd like to request this feature.
Curious as to how wifi works on the C7.
With an external dongle.

Have you tried configuring hub mesh to use tcp instead of udp? Worth a try.
How do you connect the dongle?
Scroll down to WiFi Setup.
Thanks. Always useful to know.
Good thought but I think UDP was removed as an option a few updates ago...
@JimMac are they both on the same subnet? And did you wait about 5 min after turning it all on? I found that to be helpful.

I must have slept right through that update.
Sorry to provide obsolete information!

Yes both are on the same subnet. My DHCP server assigns a reserved IP address to both hubs using either Ethernet or WiFi. Of course different IP address for each.
The only thing I did to make it work was re establish the Ethernet connection to both hubs and it connected right away.
As a test I left the hubs over night and still no connection using WiFi. What I haven't tried yet is setting the C8 only to WiFi and see if the connection drops. I'll see if I have time later to try that.
Update: Turning on the C8 internal WiFi disconnects the Hub Mesh connection.
something for @gopher.ny to look at...
Since it's running over TCP, may need to reauthorize the mesh to let it pick up the new IP -> should be able to go to the other hub and re-query for active hubs to reestablish the connection (may have to reenable Hub Mesh and reboot the C-8).
Why when both were on WiFi there were no connection between the two? The very first time I tried Hub Mesh was with WiFi only on both hubs. I would have assumed that both hubs would have broadcasted their WiFi IP address to each other. That didn't happen.
Did each of the hubs have at least one device marked to share? Also can take a few minutes before they show up also.
Some routers have a WiFi Isolation option. I.e devices on WiFi can see Internet and wired devices but cannot talk to each other. Make sure this is not a case.

I don't think this is the case as I have two older Vera hubs that were sharing devices without issue on the same network a few weeks back before I retired them, both using WiFi.
Yes I have devices shared on one hub but not the other way around.
I have since tried enabling the WiFi on the C7 and got the same result, no connection even after re-initialization. No IP address shows up in the active hubs.
I think you need to redo it. It probably internally uses the mac address which will be different from wifi vs internet.
I understand why your suggesting to redo the connection and I will soon. Still doesn't answer the question of why it failed the very first attempt I made when both hubs were using WiFi. There were no Ethernet connections involved, no different MAC addresses or IP addresses to complicate the issue during the initial setup.
Would love to hear results from someone who has the same setup or anyone with two C8 hubs while only using WiFi.
I'm assuming from the silence that this is an issue that needs to be addressed by a firmware update.
