If I leave the Eero network on Automatic, my wired SmartThings hub works fine.
If I change it to the 10.0.0.0 subnet, SmartThings works fine.
If I try to use 192.168.0.0, SmartThings loses its mind. The hub shows no connectivity. Looking in the eero app, there are two IPs assigned to the hub, 192.168.0.37 and 192.168.0.222.
If I change the DHCP assignments to 192.168.1.20-254 and reboot everything, same results. ST hub shows as being assigned to 192.168.1.37 and 192.168.0.222 (not a typo, it keeps one IP on the 0 subnet no matter what lease range I use).
I can live with the 192.168.7.0 space that Automatic uses (weird choice) but I'd rather use 192.168.1.0 if possible.
