Our household has a new 'inhabitant'. It sits there, unobtrusively on the wall, but I think it watches us. I had to sneak up on it to take its picture.
More than once it has startled me as I walked past by waking up just then.
The other day we awoke to a message that said we should just leave it alone, because it knew when we were away. It has observed and figured out when we are sleeping and when we are awake.
We can talk to it from the computer...or even remotely from a cell phone.
It gets the house toasty warm just in time for us to get up in the morning and turns the heat down at night at the right time for us to go to bed. I think we are going to like this little thermostat just fine.
