I have a Nest Gen2 thermostat and two Nest Protects connected to a ST V2 hub, running a variety of Webcore pistons. I noticed this morning that all three Nest devices seem to have stopped talking to ST at midnight last night. The “lastconnection” time shown for all three devices in the IDE are “Sun Sep 30 11:59:37 CDT 2018”, give or take a couple of seconds.
This smells strongly of “something” expiring at midnight, but what? I’m using a personal Nest developer account for the oAuth for my Nest devices, and everything in my developer dashboard seems to show all is well. There are no errors in ST that I can find, just nothing is updating from my Nest devices.
