This is a 16-year design concept plan, 15 years into the smart home industry. The second generation of "cube" series sensor hardware is designed for lifesmat: entrance guard sensor, dynamic sensor, temperature and humidity sensor, and switch series. The brain of the smart home is the smart center, which connects all the smart hardware in series. This concept is to make the smart center develop horizontally. It is a product with certain other functions, rather than being hidden at home.
