When it comes to domestic smart homes, Xiaomi ecological chain products will not be absent. In the field of smart wall switches, AQARA is a well-known brand, ranking first in the sales volume of smart switches in e-commerce channels.
 
AQARA belongs to Shenzhen Lumi Lianchuang, a Xiaomi ecological chain manufacturer, and the annual sales of the first product launched by Lumi, "Mijia Smart Home Set", exceeded 1 million, which also triggered the trend of smart home. Compared with the Mijia brand, AQARA products are more high-end, and products such as wall switches and curtain motors that are not involved in Mijia have been launched, and the price of similar products is also more expensive than Mijia.
 
In terms of manufacturing, Lumi Lianchuang adopts the OEM method, although the OEM has some unavoidable problems, such as insufficient independent control, and the quality of the product may be unstable. However, as a start-up, the foundry model allows you to focus more resources and energy on product research and development. At present, more than half of Lumi's employees are product and R&D personnel, and its energy invested in R&D can be seen.
 
Intelligent switch is much more complex than ordinary switch in structure, need to use a lot of chips and controllers to achieve constant voltage and constant current and intelligent control, in this regard, AQARA materials are not saved, the relay is produced by Panasonic, the controller is also from Texas Instruments, NXP and other large manufacturers, and the internal circuit structure of AQARA switch is very neat, and the workmanship is remarkable.
 
AQARA wall switch is divided into single fire version and zero fire version, the single fire version of the single key price is 179 yuan, and the zero fire version of the single key price is 139 yuan. The difference between the two is in the two aspects of support power and wiring holes, in terms of power support, the single-fire version supports 3-800W, which can only control ordinary lamps, while the zero-fire version supports a maximum power of 2500W, which can be used to control high-power electrical appliances.
 
In terms of wiring requirements, the single-fire version has two wiring holes, and the zero-fire version has three, which needs to be connected with one more neutral wire. Most of the houses have no zero line for the electric light line, and it is more convenient to choose a single-fire switch; The socket circuit in the room or the lighting circuit of some new communities is buried with a zero wire, and both the single-fire version and the zero-fire version can be used. When purchasing, users need to confirm the buried wires of the switch circuit at home to avoid incompatibility.
