Q&A | Which company in China is doing the best for wireless smart home?

The wired smart home is gradually eliminated by the market due to cumbersome cabling, difficulty in promotion, and high cost. The wireless smart home system pays more attention to simplicity and convenience of maintenance. So now what is the best wireless smart home company in the country? Take a look at how netizens say.

Netizen 1: A few years ago, when talking about smart homes, people still remembered that they had to open up the walls. The wiring was dense, impeding the appearance, high cost, difficulty in upgrading and updating the system, and after-sales service, because the lines were buried and led to fault diagnosis. Both have seriously affected the satisfaction of consumers and cannot be accepted by customers. Now, with the rise of the Internet of Things technology, the smart home has ushered in the second revolution, the level of intelligence has greatly improved, and gradually formed four major wireless technologies to lead the smart home.

1.WIFI technology

Smart home products based on Wi-Fi technology are the most common. Their advantages are the fast transmission rate, low product cost, and the most popular life. For users, the Wi-Fi-based smart home combination is the most convenient and the equipment is directly purchased. Network can be. There are two aspects of everything, although Wi-Fi is fast and widely used, it also has its own technical disadvantages. The biggest problem is that it has very low security and weak wireless stability; the large power consumption is also one of its weaknesses. Caused its limited application in the home field, such as smart door locks, infrared relay controllers, various sensors and other inappropriate use; In addition, Wi-Fi networking capabilities are relatively low, the actual size of the current Wi-Fi network Generally not more than 16 devices, but in the actual home environment, only the number of switches, lighting, appliances has been far more than 16, obviously the development of space has been limited.

2. Zigbee technology

First of all, the security of ZigBee technology is very high, and so far there is no global precedent for hacking. Its security stems from its systematic design: using AES encryption (advanced encryption system), 12 times more stringent than the bank card encryption technology; secondly, Zigbee uses a honeycomb structure networking, each device can pass multiple directions Communication with the gateway provides high network stability. In addition, its theoretical network node capacity is 65,300, which is sufficient to meet the needs of home network coverage. Even intelligent communities and smart buildings can still fully cover.

Finally, Zigbee has the ability to communicate in both directions. Not only can it send commands to the device, but the device also feeds back the status of the execution. This is critical for the end-user experience, especially for security devices. If you click close, you don't know the door. Whether it is really locked, it will bring much security risks; In addition, Zigbee uses a very low power design, can be fully battery-powered, theoretically a battery can be used for more than 10 years, energy saving and environmental protection.

3.Zwave technology

Zwave's data transmission rate is 9.6kbps. The effective coverage of the signal is 30 meters indoors (outdoor is greater than 100 meters), suitable for narrow bandwidth applications, and has a certain degree of security and stability, but currently only used in home automation. The main disadvantages are as follows: First, fewer nodes, the theoretical value of 256, the actual value may be only about 150, is considered to be able to accommodate the upper limit of the number of devices, in fact, many manufacturers can accommodate 20, 30 devices is good The second is the tree network structure. Once the upper end of the branch is broken, all devices at the lower end cannot communicate with the gateway. Third, there is no encryption, security is poor, and it is vulnerable to attacks. (The frequency band used by Zwave is non-civilian in China. Zwave smart home is not common in China, and more is still applied abroad.

4. Bluetooth technology

The family is familiar with Bluetooth technology, I am afraid it is a Bluetooth function on the phone. Its power consumption and cost are both between Wi-Fi and Zigbee, but the transmission distance is the shortest and belongs to a point-to-point, short-distance communication method. Due to transmission between mobile devices or short distances, Bluetooth products will provide some of the more personal use experience, such as Bluetooth headsets, Bluetooth speakers, smart scales, etc., due to its short transmission distance, it is not suitable for the formation of a huge family The internet.

Looking at the moment, no matter what kind of technology is still in the stage of immature, as to who is the wireless technology who is still waiting for further observation.

Netizen 2: Unexpectedly, this topic, dissatisfaction, downstairs answer is a one-sided statement, but also do not know what level of smart home, I just do smart home from the media, if you say the best, then No, what technology is mature is what I say more than anyone else, because I've been doing it for three years, and I've done it myself since then. I've done better now. There are lions, Han, and Ziguang. The best is not.

Netizen 3: This problem feels like a pit! At present, smart home is still in the late stage of cultivation, or in the early stage of growth, there is no such thing as the boss and the second child. Many smart homes can not be covered by only one manufacturer's product. , Wireless smart home should be more millet from the number of users, in terms of single product shipments and total amount, millet should also be the most, but at most it does not mean the best, it should be the best latitude is excellent Such as professionalism, intelligence, service capabilities, market size, and user satisfaction, these are obviously not the best among the so-called industry agencies.

Netizen 4: Domestic wireless smart homes have also developed in recent years. No one dares to say that they have the highest market share and quality is the best. Therefore, the rush to judge the best or worst wireless smart home, which is likely to be unfair, wireless home smart good and bad, usually see a manufacturer's communication technology, hardware and software cloud system-level independent innovation capabilities. In terms of system compatibility and independent innovation, Huawei, Oerlikon, and Xiaomi are in the first echelon. Unfortunately, Huawei itself does not involve itself or provide smart home hardware. Their systems have been compatible with three or more communication protocols, and their systems can be connected to most types of smart home hardware. Eco-chain vendors following their respective systems are at least two digits or more. Personal opinion, do not spray.

Netizen 5: The smart home was a little inconsistent. 18 years ago there was this thing at the high-tech fair. Actually, there was no qualitative leap after 18 years. If we say that a mobile phone tablet remote control app opens a light and a window curtain is called a smart home, then it is too weak, but the reality is that this is a concept at this stage. It is estimated that there will be no major breakthrough in five years. . Because the basic home appliances do not have a unified standard protocol, can not be unified network is also talking about intelligence? It is nothing more than a piece of APP in the remote control switch. Of course, everything starts from the concept and it does not oppose exploration, but opposes speculation and money.

Netizen 6: A big pit, the smart home needs to be set up to see the hidden equipment is too much, and now even smart home wants to achieve what kind of smart state is completely unclear, and now some are automatic curtains , Automatic lighting, according to the human body, temperature, switch air conditioners, purifiers, these simplest things are just automation, completely out of intelligence! The current level is a false proposition! But the direction is positive, now automatic The strongest home is coarse grains! No one!

Netizen 7: There is no one who does the best, just to look at the one that suits you, and the products that they implement are similar, and the realization of the functions are basically the same, but just to see which products have different characteristics to attract customers, just like AmazingBOX smart home host, not only can be compatible with third-party devices, but also able to DIY scenarios, with NAS and wireless dual-frequency routing capabilities, these features are enough to attract me.

Netizen 8: Although the views are different, but the experience is still very important, this point, I am still more appreciative of the products of amazingbox.

Netizen 9: Purple is suitable for villas, office buildings, real estate projects, etc. Haier is a complete set of smart appliances, each with its own merits and demerits.
