Air Con remote
Our house has a weird problem. There are 4 air con units in the three room house and some aircons are so close to each other that if you need to turn one ON without turning the others ON, you will need to defy the laws of physics, and sometimes even the laws of quantum mechanics and/or law of conservation of energy. Usually we end up switching one air con ON and then take a trip around the house to see what else got turned ON and then turn them OFF using our own algorithms....
