Now I see a problem disconnecting from Nest. I logged into my Nest account and removed the 15 or so connection entries, then returned to Rachio. In hindsight, I should have disconnected from whatever one of those connections was active before removing them from Nest. Now, when I try to disconnect, I get the same maroon\red error bar popping up from the bottom and telling me there's a problem disconnecting.
Again, no worries. I'll wait for v2 to come out. Maybe a software and firmware refresh will solve all of this.
