As a major part of the smart home system, intelligent lighting control is a fundamental part. Everyone chooses the ordinary switch, the most important is to choose the brand, choose the price, choose the appearance, choose the material, then for the current intelligent switch, in addition to these, the most important thing to consider is the performance, communication technology, networking mode, function. And the service above. Come one by one.
1, choose a brand
The current smart switch brands are basically new brands, which belong to a hundred flowers, and the smart homes in the world have not worked for a few years. They still can't precipitate an excellent leading brand, and the smart switches are products with fast technology updates. You are leading and may be replaced by better products from other companies next year. Just like Nokia in mobile phones, the brand is loud enough, but are you still going to buy this brand now? So for smart switches, brand is not a key consideration.
2, choose the price
Smart switches are generally more expensive, especially with respect to conventional switches. The same is a set of three-bedroom, two-bedroom and two-bedroom units. The average switch costs about 1,000 yuan, and the imported brand intelligent switch sets about 15,000. Other prices are hard to say. The cheaper smart switches are more than 2000 pieces, most of which are About 5000, everyone can look for it on Taobao, this is mainly to see the individual's ability to withstand. Personally think that compared with the renovation of 200,000-300,000, a set of intelligent lighting control system with several thousand yuan is completely acceptable, and the situation has brought many upgrades to the home.
3, choose the appearance
Intelligent switches, the current appearance is mainly divided into three forms, respectively, traditional switch, touch, liquid crystal touch. This is also a personal hobby. However, personal advice, the traditional switch type does not have to be considered, just like the feeling of a button phone now. Touch type also has to look at the design's good or not, many switch designs do not reflect the sense of smart technology. The current mainstream, should be LCD touch type, using LCD glass screen, with pattern design, a variety of switch buttons at a glance, the appearance of the appearance of the grade, it is recommended.
4, communication technology
Smart switches are IoT devices, and each switch has a unique address. It embodies intelligence, mainly to achieve remote control. In other words, the local switch can control the light on the off-site switch. For example, the switch at the gate can control the lights in the bedroom. In this case, a network is needed between the switch and the switch, and the way in which this communication technology is networked is a key issue that we need to consider. There are mainly the following situations:
Case 1: The wired version switch requires a signal line (weak current) connection between the switch and the switch. This applies to the stage where the hydropower has not yet started, because this requires consideration of the problem of weak wiring. The current wired version of the smart switch generally adopts 485 communication technology. This technology has been developed for many years. Various international mainstream smart home systems adopt this technology, which is very mature and can be easily combined with the mainstream central control host to upgrade to the whole. Smart home control. In addition, some people worry that wireless may have radiation, so the cable is more reassuring. Personal suggestion that if the signal line can be used, the wired version of the switch can be used.
Case 2: The wireless version of the switch, compared to the wired version, the main advantage of the wireless version is that there is no need to lay the signal line, and the switch and the switch directly connect to the network through the wireless signal, so that there is no need to lay the signal line. Some users have already installed the wireless smart switch because the water and electricity wiring has been laid. For the wireless version of the switch, there are currently three main wireless technologies, namely 433M RF technology, Zigbee technology and wifi technology. Specific technical experts can go to see the advantages and disadvantages, personally recommend the use of Zigbee technology, which is also the current international mainstream wireless technology, signal stability, scalability, 433 RF should not be considered, wifi sometimes not too much signal Stable, poor wall penetration.
5, networking form
The current intelligent switch, whether wired or wireless, is a large part of the networking form, which adopts the central control networking mode, that is, a central control device is needed first, and then a signal is sent from the central control to control each switch. In this case, you must have a central control device. If there is a problem with the central control, it will be completely useless. The new generation of intelligent switches, each switch is a separate host, can be run separately, can also form a network, can run without the need for central control equipment. In addition, even if there is a problem with the switch, it will not affect the normal operation of other switches. Therefore, try to use the smart switch that does not require a host.
6, performance
The new generation of smart switches are all chip-like. Just like a computer, the better the performance of the chip, of course, the better the performance of the switch. The more powerful and flexible the function, the access switch in a network range. more. Many smart switches are still using 8-bit chips, some are 16-bit, and the high-end ones are 32-bit chips. In addition, from the point of view of the number of switches in the network, some smart switches can only connect up to 10 switches, and some can access more than 200 switches, from which performance differences can be seen.
7, function
Choosing a smart switch, of course, the most important thing is to choose this switch function and features, can not meet the user's individual needs, otherwise it is useless in good performance. Since it is a smart switch, we must first meet the basic needs of the user, and at the same time meet the user's many unexpected ideas. The most common requirements of intelligent switches are: multi-control, some switches are called smart, but only rigidly provide dual control, 3 control, which is actually not smart. The real multi-control, it is to think how much control is how much control can be achieved, for example, I think more than 10 switches in the home at the same time a multi-control of a certain lamp, in theory, can be done. There are also various scene modes, which can be set according to your needs, instead of a fixed bedroom, a scene, a living room, and this is not smart. In addition, there are still many functional requirements for smart switches. This is mainly to see the user's own choices, to meet your basic needs, does not mean that the switch is smart, the specific is still to see more comparison.
