Before, I try to create an app for my unique situation, I figured I would ask to see if someone already has an app or code I could use.
I live in a house built in 1910. We had all new electrical and plumbing put in when we moved in. On the 3rd floor though the breaker is only 15 amps. As we learned this winter, heat does not keep well on this floor and the furnace has trouble pushing this far up. We used a small plug in heater for the winter but we were unable to plug in two unit (one for each room) as it would draw too much and trip the breaker. We put the heater in the windowless hallway between the bedrooms and it worked just fine. As are approaching Spring, I expect to have to put window AC units in each room. Problem is, running two units at the same time will trip the breaker (like the heater problem).
I am thinking someone has had this issue before and created a SmartApp to control two heavy duty switches from temp sendors in the rooms. This would be a similar setup to the SmartApp, Vertual Thermostat. The app would set desired temp from a calendar (like BASIC 5-2 DAY PROGRAMMABLE THERMOSTAT SCHEDULER). Here is the kicker. The app would need to prevent both switches from being on at the same time.
Thanks for the help.
