With the increasing popularity of smart products in recent years, Chuangxinwei believes that smart home must be a rapid development trend in the future, with WiFi technology with short distance transmission, high speed and other characteristics, WiFi module will definitely penetrate into every aspect of smart home.

Under the background of the rapid expansion of the smart home application market, Chuangxinwei also launched the MS11SF1 series WiFi module, using ESP32-C3FN4 high-performance chip, and is also a module combined with Bluetooth, full IO port, supporting AT, ESP-IDF development.

In summary, the application of WiFi modules in the field of Internet of Things and smart homes is promising and promising.

Let’s introduce the role of Xiaomi smart home gateway

The so-called Xiaomi smart home gateway is similar to a small intelligent processing center of a family, which can link a variety of intelligent or automatic products to achieve some functions, such as induction, timing switch, and abnormal alarm.Home smart wireless remote control doorbell

As the hub of the smart home, the role of the gateway is very important, Xiaomi intelligent multi-mode gateway, while supporting Zigbee, Bluetooth & Bluetooth Mesh three communication protocols, basically covering all sensors, electric curtains, wireless sockets, and smart door locks and other devices.

It can also be connected to HomeKit, which can be controlled with Siri. Compared with the first generation of gateways, the lights are removed, but this generation supports more protocols, the coverage is larger, and the function of the Bluetooth gateway is also more stable and easy to use than Xiaoai classmates or other devices built-in.

What types of gateways?

Single-module gateway: It is a gateway with a single communication protocol

Multi-module gateway: It is a gateway that has multiple communication protocols at the same time.Home WiFi for the elderly

At present, children’s shoes protocols in the smart home field are commonly used: Bluetooth/Bluetooth mesh, zigbee, Wi-Fi.

Communication protocols are like voice, and the same communication protocols can understand, communicate, and interact with each other. Different communication protocols need to be assisted by a translator who understands multiple languages – that is, multimode gateways

Wi-Fi (no gateway required): It itself is directly connected to the network, this kind of does not require a gateway, there is a Wi-Fi router can be.

Therefore, devices that support Wi-Fi protocol do not need a gateway to help network, and smart home linkage can be realized directly through the router.Smart home products

Bluetooth: It does not have the ability to directly connect to the network, so it needs a gateway to help with networking, so as to realize the linkage and remote control of smart homes. (Just like the smart door lock of Bluetooth, to realize the remote control function, a gateway is required)

Zigbee: This communication protocol itself does not have networking capabilities, so it also needs gateways to help network, so as to achieve smart home linkage and remote control;

However, the great thing about Zigbee is that it can establish an ad hoc network, that is, in the case of a network disconnection, they can still achieve smart home portable wifi

Simply put, in the case of a network disconnection, the Zigbee transmission protocol device can still be used normally. In addition to remote control and voice control that require networking.

What you need to pay attention to when buying a gateway:

At present, the Internet of Things has not yet realized the interconnection of all things or all interconnection, so the gateway is also opened up within its own ecology and can only be used for its own home. Not to the point where I can just buy one and use it.

If you do your own smart home, it is recommended to buy a multi-mode gateway. In this way, when configuring the device, you can choose more devices, and you don’t have to worry too much.
