It means that every element of your house can be controlled from a panel on the wall or your phone.2.. Use your mobile to power them on or off,and you may feel truly modern or truly lazy.

Doing so, the room will be at a desired temperature when necessary and switches on a power-saving mode when not occupied. Similarly, by installing a CO2 sensor, you can have an automated ventilation (通风) system.4..
