Although the concept of smart home is vague, it is deeply rooted in the hearts of the people. I don’t know when it started, the smart home entrance competition has evolved into a beach landing, and the trend has become more and more intense as time goes by, although the manufacturers are fully committed to constantly innovating, but they are biased. No product can be as popular as the concept of smart home. There are a variety of products in the smart home series on the market. The TV, remote control, LED lights, sockets, routers, etc. can all be used as smart home products. change.
Perhaps everyone still has the impression that not long ago, Aiban.com disassembled the iMagic smart LED light based on Bluetooth® 4.0, the colorful lighting effect is really dazzling, but after that? The general impression left us is not too Practical, entertainment-only information. From this point of view, although the smart home products are novel and fashionable, they only meet the needs of real life, and the products that provide practical use can meet the tastes of the public and get everyone’s approval. Therefore, the following will bring you a more pragmatic smart home products - Zitombo smart LED lighting kit based on Zigbee technology, see the picture below.
Magic Teng Intelligent Lighting Set
The Magic Teng Intelligent Lighting Set uses a simple cow cardboard box. When opened, it will find 5 small boxes inside, which are Nova lamp*2, free switch*2, gateway*1, which power the gateway. 5V output adapter *1, a simple explanation page, 3M sticker, as shown below. Of particular note is that each small package has a unique two-dimensional code for the device inside the box. This is important when configuring the mobile app.

The communication control interaction principle of the Magic Teng Intelligent Lighting Kit is based on Zigbee technology. It has also been introduced in the Atmel ATMEGA256RFR2 Xplained Pro development board evaluation. Zigbee is based on the IEEE802.15.4 standard, but it is an extension of the IEEE802.15.4 standard. IEEE802.15.4 only handles the low-level MAC layer and application layer, while ZigBee standardizes its network layer protocols and APIs, as shown in the figure below.
ZigBee standard
Physical layer: the lowest level of the protocol, the task of directly interacting with the outside world, controlling the operation of the RF transceiver
MAC layer: responsible for data transmission and reception of the establishment, maintenance and end confirmation mode of the wireless data link between devices
Network layer: establish a new network, ensure data transmission, encrypt data, and ensure data integrity
Application layer: The application support layer enables communication between multiple devices according to services and requirements, and can be developed independently according to user needs.
ZigBee works in the global ISM license-free 2.4G frequency band. It is a low-speed (20~250kb/s), short-distance (10~100m, increased RF transmit power that can increase the communication distance to more than 1KM). But it is low-cost, low-latency (15ms~30ms), low power consumption and powerful networking capability. It can support 65000 nodes and support multiple network topologies. Two sets of LED lights are equipped from the Magical Intelligent Lighting Set. The switch and a gateway can also be seen one or two.
The Magic Light calls its own LED light a Nova light. Of course, this is just a name, meaning "new" and "light", not a special lamp. The Nova lamp adopts the same design structure as the iMagic LED lamp (see the figure below). The standard E27 screw buckle is suitable for most household use. The Nova lamp is rated at 6W and can be used in AC environment of 100V~240V. This wide voltage supply design is very good, even if it is used abroad, there is no problem at all. What makes me most impressed is that the Nova lamp has no spare capacity in the heat dissipation design. The heat dissipation design of the aluminum grid can minimize the heat generated during LED operation. It is safe first, although the feel of the Nova lamp is very poor. But who would be fine with a light bulb?
Nova lamp appearance
A simple switch, also named by the illusion, is a free-to-open switch. It is obvious that this switch is very flexible in life. With the 3M sticker attached to the switch, you can place the switch on whatever you want. The place is really worrying.
The free-standing switch is a round square design (see the picture below). It is the size of an adult slap, and the front has a matte design. It feels great, but the feedback of the button is only clear when the middle of the switch is pressed. The internal design of the button is processed. It should be rough.
