I still can't understand someone in bed using changing the thermostat as a normal action. The average dude is not going to be doing this.(again IMO)
I have a two story house. The thermostat is down stairs. I also have dogs that sleep in the bed that can make it a pain in the ass to get back to sleep should I get out of the bed.
With a two story house, it's sometimes more complicated than just setting the thermostat to X degrees and enjoying a consistent temperature. If the cycle stops for a long time, it may heat up upstairs and remain cool downstairs.
I leave an old iPhone sitting next to the bed. It's great to be able to control the thermostat if I wake up and feel hot (or turn the heat on and wait under the warm covers, if it's a cold morning). I can also control the ceiling fan and lights from the same controller. My next project is motorized curtains.
It's not all that far fetched or crazy. The Aria hotel in Vegas has this same sort of home automation stuff in their hotel rooms.
