Good, soon to be great. – QuickControl: for Nest Learning Thermostat® Review

Initially thought it did not work on watch. Turns out works great on watch if system is on. The company was fast and persistently trying to figure out the problem. They expect a fix within a couple of weeks. Until then if your thermostat is off you will not be able to turn it on via the Apple Watch. Not a huge issue but will be fixed none the less.
