Edit this script for the date and time to turn off the house thermostat heater.
The Wemo Switch turns on and off a small heater located under the house thermostat to fool the thermostat into about a 15 degree set-back. By turning it on when leaving for a vacation and having IFTTT turn it off a few hours before returning home, we come home to a warm house. All other timers can only time for 1 week or less. With this "Recipe", we can leave for vacation for many weeks but still come home to a warm house.
