Should have included you in these links. I am having a slight issue with the T-Stat in the app. App shows not connected to WiFi, but I am able to control the T-Stat from the App and it also shows full signal as well. The T-Stat itself does not show no WiFi.
I submitted 2 logs:
From Today - 611786
From Last Night - 611140 (NOTE: Removal of the T-Stat and plugging it back in seemed to correct the display to show connected)
