The Xiaomi Mi Smart Sensor set includes the Mi Control Hub, 2 Mi Window and Door sensors, 2 Mi Motion Sensor and one Mi Wireless Switch.
The Mi Control Hub is like the brain of your smart home ecosystem. Pair it with your other Mi Home devices and set the rules for their behaviours. You can even set up a chain reaction of commands.
The Mi Smart Sensor Set enables an additional level of automation in your house. Now you can set the rules of when your devices will work, not work when functions are activated etc based on sensor readings. You can add more sensors bought separately to monitor more and more rooms.
All rules and automation are set up directly on the Mi Home App through a simple interface. Once this set is installed other Xiaomi products in your account will be connected to the Smart Sensor Set.
