Just for grins, what sensors does it show? The barometer (as I found out) IS in the Smarthub/Access. Cold boot the Smarthub (remove both cables, wait a couple of minutes, then reconnect: Network, then power).
My smartHUB is not displaying barometer or rainfall. I tried "hard reboot" suggested above and did get it to go from displaying Red to Green, but still no barometer or rainfall indicators. Is Access any better or is the whole internet interface junk?
