Sometimes we could forget turning off some home appliances after we leave home, which not only leads to a waste of electricity energy but also wears the lifetime of the home appliances down. “Intelligent key” is designed to solve the problem. Combine the main switch of home appliances and the key and we can control the home appliances to be on and off. The way can both protect the home appliances and reduce unnecessary waste.
