A gateway also needs to be added when Bluetooth devices are remotely controlled. Bluetooth basically supports Mesh now, but Bluetooth Mesh is still not as stable as ZigBee when controlling many devices. Considering that most families have a limited number of devices, it is recommended to use Bluetooth Mesh, which is low in cost. This is estimated to be the main reason why Mijia mainly chooses Bluetooth, but the sensor is still mainly Zigbee because of low power consumption.

Of course, optimistic about Wi-Fi! First of all, from the perspective of current home networking solutions, Wi-Fi must be the first choice. Whether you use IoT appliances or not, most households will use Wi-Fi; secondly, low-power Wi-Fi modules have been developed and launched. If it can compete with ZigBee, the low power consumption advantage of ZigBee is not so obvious, and the possibility of choosing Wi-Fi will be greatly increased.
Bluetooth, Wi-Fi, ZigBee, which one is better for data transmission?
Wi-Fi is undoubtedly the fastest wireless technology at present. With the popularization of Wi-Fi in large public places and office areas, people are thinking of connecting to Wi-Fi wherever they go. The user experience is excellent. Wi-Fi -Fi has become an essential thing in life. Why are people so reliant on Wi-Fi? The reason is very simple. The transmission signal of Wi-Fi is stable and fast, and the amount of data transmitted can also meet the needs of most industrial users.
However, Wi-Fi also has disadvantages such as poor security, weak stability and high power consumption. In terms of the number of device access, Wi-Fi is also very limited.
As a competitor, Bluetooth technology is often used for short-distance communication, with low power consumption and fast response speed, but it has the disadvantages of limited transmission range, poor anti-interference ability, weak ability to penetrate walls, and the transmission rate and data transmission are difficult to compare with Wi-Fi. compared to.
ZigBee is a short-range, low-complexity, low-power, low-cost two-way wireless communication technology. Higher security, low-rate transmission, long transmission distance, and simpler protocol than Bluetooth. The biggest feature and biggest advantage is that it can self-organize the network, and then link the direct data of each device through the central node. ZigBee is considered to be the future trend of whole-house intelligence.
Compared with Wi-Fi and ZigBee, Bluetooth has many disadvantages. Why do many users still choose Bluetooth?
With the continuous innovation of data transmission and Internet of Things applications, Bluetooth has evolved from the ancient classic Bluetooth to Bluetooth 5.0+. The standards above Bluetooth 5.0 have greatly improved functions such as data transmission bandwidth, transmission range, broadcasting and coexistence. For IoT applications – smart home users and developers, the transmission range will be increased to 4~5 times, which will be a significant advantage of Bluetooth, because it breaks through the distance difficulty of Bluetooth technology in smart home applications.
In addition, Bluetooth also has the advantage of low power consumption compared with Wi-Fi. Compared with Wi-Fi technology which consumes a lot of power, the advantages of Bluetooth used in smart home products are also very obvious. To a large extent Has the potential to change the landscape of the smart home market.
All in all, Bluetooth 5.0+ is a technical specification for the Internet of Things, smart home appliances and smart wearable devices. Bluetooth 5.0 is still ahead of Wi-Fi in these fields. There is still an irreplaceable position in transmission and mobile network sharing. For the highly intelligent home life of the whole house, ZigBee can access more ports than Bluetooth and Wi-Fi, which is an incomparable advantage.
Therefore, for the question of whether to choose Bluetooth, Wi-Fi or ZigBee, it is still necessary to compare the respective advantages of the modules, and then make a conclusion based on the actual application scenarios and their own needs.
Only by choosing different smart home connection methods according to the equipment and the specific space environment used can the maximum advantages of the connection protocols be brought into play.
