Anyone ever heard of a thermostat/switch that could replace a wall switch? Basically, I have a bathroom with a combo light/fan/heater, with each function on its own switch. I basically never used the heater over the first winter because no one is waiting for the room to warm up before sitting on the toilet. I'd love to have a switch with a thermostat function, so I could set it to a specific temp and leave it 'on' all the time. Even better if it has timer/scheduling built in, but I don't have high hopes for that.
