My old house had the thermostat right behind where I put the TV. Running the TV screwed up the thermostat. My new house has the thermostat somewhere the sun sometimes shines. I suppose I could relocate it to the other side of the same wall.

What kills me is that Nest built in some fancy IR and visible light sensors. They have all the information they need to know how much heat the thermostat is absorbing from ambient light. Some poor schmuck just needs to run a bunch of lab experiments to come up with a suitable model. I wouldn't expect that from a $25 thermostat, but my expectations are higher for a $250 unit.
