Comparison Xiaomi Mi Smart Sensor Set vs Xiaomi Mi Smart Home

The number of motion sensors supplied with the central unit.

This number determines how many areas can be covered with the out-of-the-box kit without purchasing additional equipment. Motion sensors can have different coverage angles and response ranges (see below for all this), however, when choosing, you can proceed from the fact that one such device is usually enough for a living room or a medium-sized office space. Accordingly, the number of motion sensors approximately corresponds to the number of rooms for which the set is designed in the original configuration. It is usually small, two or more sensors are extremely rare: it is assumed that, if necessary, it is easier to purchase additional sensors separately.

Number of opening sensors supplied with the central unit.

This number corresponds to the number of doors that can be equipped with an alarm system using only this kit “out of the box”, without purchasing additional equipment. Note that opening sensors are rarely provided in the kit more than one : this allows the user to buy the alarm kit they like without fear of overpaying for extra equipment, and if more sensors are needed, they can be purchased separately. In addition, some sets are not equipped with such sensors at all.
