That’s what I meant, the device is directly next to the heat source. It’s never going to be accurate. And you can tell in the way people use the two systems. In Germany, people don’t think about our check the temperature of the room or what the dial is set at, just, I’m cold, turn it up. In the US, the room is set to a specific temperature and just left alone except for day/night, home/away.

But, anyway, the comment was about how they wouldn’t work for Nest, and that’s true. You’d need a third party solution. It would be hard to sell these and then say, hey, by the way, you can’t use it until you go out and buy something from someone else and install it
