10minutes to know Smart Home Technology
What is smart home technology?
Smart home technology is a collective term for information and communication technology used in houses, where the mutiple components are communicating via a local network through technology such as ZigBee, Zwave, Wifi, KNX, EIB, X10 and so on. It is widely used to monitor, warn and alarm, regulate condition and carry out directive ordered by users. Smart home technology also makes item have automatic communication with the surroundings to have linkage and joint performance via the Internet.
Smart home technology can bring you a totally different experience and convenience than does conventional home devices and appliances, because of wire or wireless high-tech base. Traditional home products are signle and secluded, cannot be controlled by a controlling device, thus people should operate them manually as well as at the scene. However, smart home technology allows one center terminal to control your home appliance remotely. Even you are thousands of miles away, smart home can also give you a positive support to help you regulate house conditions. For example when friends visit your house but you are absent, you can use your cellphone or tablet PC to open your door lock remotely.
Smart homes technology can not only offer you great convenient living standard but also support to build a safer and secure house condition. Smart home contains fields of security protection items, such as camera, smoke detector, IR motion detector, etc. Good physical protection is guaranteed in smart home so as to help you no longer to worry about any hidden security risks. Therefore, your family members can enjoy a high-caliber lifestyle.
Sensor
Sensor is used to monitor and measure activities in the surroundings. It can collect surrounding data in the house. For example, temperature and humidity, light, sounds, movement, gas, air, smoke, water and so on. These sensors work as body capillary to sense change and transmitter data to center controller.
Controller
Controllers make choices based on programmed rules and occurrences. Controller can change the scene condition manually or automatically. They turn on or off one or more items to reach a satisfactory effect users’ needed. For instance, smart switch can be turn on by itself or user and smart curtain can also be opened when ambient light outside is enough strong.

'Smart Homes' Could Be Hacked If Not Choose Wisely:
Do you want your house to be haunted by a complete stranger?
“I can see all of the devices in your home and I think I can control them,” a complete stranger said to Thomas Hatley who lives in Oregon and had been awoken with an early phone call on a Thursday morning.
He and his wife were still in bed. Expressing surprise, he asked this stranger to try to turn the master bedroom lights on and off. Seconds later, not only lights, but also television came on. “I’ll be darned”, Mr. Hatley said in the phone.
This is not a fabricated story, but a true report on Forbes Tech.
The home automation market was worth $1.5 billion in 2012 according to Reuters; there’s been an explosion in products that promise to make our homes “smarter.” Many of these products have smart phone apps and Web portals that let users operate devices, cameras, and locks from afar. The function sounds really amazing, and so many people embrace this new lifestyle without thorough consideration and cautious selection. Here’s problem: as we bring the things in our homes onto the Internet, we run into the same kind of security concerns we have for any connected device: they could get hacked!
To prevent being hacked, you need to pay attention to more than function. All functions provided by different brands are similar, remote monitor, remote control and automation. However, technologies of networking behind functions are so much distinct. It could be as simple as Bluetooth, radio frequency and Wi-Fi, or be more advanced one such as Zwave and ZigBee.
Contrary to lots of smart home brands who were exposed to have hacking problem, Wulian receives zero report of hacking issue. From the very beginning, Wulian sets network safety as its priority. Smart home function only makes sense after safety is guaranteed. Otherwise, how could people feel relieved to let an automation system take over their houses?
Googling a very simple phrase led me to a list of “smart homes” that had done something rather stupid. The homes all have an automation system from Insteon that allows remote control of their lights, hot tubs, fans, televisions, water pumps, garage doors, cameras, and other devices, so that their owners can turn these things on and off with a smart phone app or via the Web. The dumb thing? Their systems had been made crawl-able by search engines – meaning they show up in search results — and due to Insteon not requiring user names and passwords by default in a now-discontinued product, a stranger was able to click on the links, giving me the ability to turn these people’s homes into haunted houses, energy-consumption nightmares, or even robbery targets. Opening a garage door could make a house ripe for actual physical intrusion.
The ZigBee technology is a perfectly suitable choice for developing smart home. Its strict encryption is born for resisting hacking. Wulian is an advanced member of ZigBee Global Alliance and participates in the establishment of home automation industry standard. From network reliability to the safety of user data on server, Wulian has all considered thoughtfully.

Have you have the experience that you forget whether the light is turned off after leaving the office or building ?
Now, with Wulian ZigBee wireless smart switch, you can check the status and switch on/off the lights in your office or building remotely at any time and wherever you are. This is based on the two way communication and real time feed back features of ZigBee wireless protocol technology. Besides, the brightness of the lights is adjustable from 0% to 100% degree with Wulian dimmer switch even for LED light.
The first thing we have to do is turn on lights when entering office in the morning because of the duskiness outside on cloudy days. However, when it comes near noon and gets brighter outside, It is a waste of energy if we forget to turn off the lights because of concentration on the work.
With Wulian wireless light sensor and switch, We can create linkage between them. When light sensor detect the brightness in our office is more than (for example 2000Lux), it will trigger the lights to switch off automatically.
There are many lots of lights in one building and it is troublesome to turn on/off switches one by one every day.
With Wulian wireless scene switches, just one touch on your cell phone or the scene switch panel, all the lights will be on/off automatically. What is a scene? We can put single device function together into one scene and these devices are selected or changed as you like. Just with one touch on the scene switch or cell phone, all the devices will work or stop working automatically.
Then after work, how to solve this problem if the last staff forget to turn off the lights when leaving the office?
We can set timing with Wulian wireless smart switch, for example, lights in the office will switch off automatically when it is 6:30pm after work.
2.Electrical appliance control:
We have various appliances in the buildings especially for residential buildings, such as air conditioner, refrigerator, water heater, microwave oven, washing machine, TV, projector, Stereo System, ventilation system, electric curtains, etc and all these appliances are power by electric.
According to report of IEEPA, the average standby power consumption of one TV set is 8.07watt/hour, washing machine 2.46watt/hour, refrigerator/4.09watt, air conditioner 10watt/hour and so on. This is a huge waster for energy. What’s more, how can we know that if the electric power consumption is abnormal (for example, electric leakage)?
With Wulian wireless smart socket, IR transmitter, we can help to solve this problem.
Before leaving your office, just with one touch on your cell phone or the scene switch panel, all power supply for the electrical appliances are cut off and there will be no standby power consumption.
Besides, we can set timing, when it reaches 6:30 pm in the evening, all the power will be cut off automatically.
For abnormal of electric power consumption, we have current detector socket. It can read the current, voltage, power and other data and the statistics of power consumption for every week, every moth, or every year, warning message will be sent to you if power consumption is irregular during a certain period.
For the appliances (such as TV, air conditioner, projector, etc) that need remotes to control: We have IR transmitter which can learn every command of the pushbutton on traditional remotes. Just throw away all the traditional remotes, only with one Wulian IR transmitter, you can control all these electrical appliances with your cell phone or scene switch.
We can not only turn on/off these electrical appliances but also can set timing when to turn on when to turn off. Have you ever thought how to achieve the home theater system or office meeting mode?
Just one touch on your cell phone or scene switch, all these devices needed switch on/off automatically at the same time. No need to trouble to find this remote that remote and so on. What a wonderful and convenient life!
3. How to live a constant temperature, constant humidity and constant oxygen life ?
Wulian air quality detector is to detect the density or concentration of carbon dioxide, voc, formaldehyde and other noxious gas in the house or building. For example, we can set a scene that, when the density of dioxide is more than 1000ppm, the ventilation system will switch on automatically and fresh air will flow in to the house or office.
Wulian temperature& humidity sensor is to detect the surrounding temperature and humidity in our house or building. We can set a scene that when the temperature is lower than (for example 5℃) in winter, floor heating system will work automatically. In summer, Air conditioner will switch on automatically if temperature is more than 34℃ and it will switch off if temperature lower than 25℃,this is not only good for our health but also for energy saving. Moreover, we can set timing that only from Monday to Friday the scene works, on Saturday and Sunday no need to execute the scene.

As the development of science and technology, smart home has achieved significant progress, especially due to the application of wireless communication technology, smart home has made qualitative leaps. Compared with traditional wire communication technology, wireless communication technology is featured with stronger expandability, easier promotion, lower cost, and also avoids the trouble of drill which is necessary for traditional wire technology. As a result, it becomes a trend in the global communication field and enjoys more advantages in the application of smart home system. At present, the major popular wireless communication technology applied in smart home are Bluetooth, Z-WAVE, ZIGBEE, SMART ROOM (ZIGBEE HA standard), etc., and of course, WIFI is also involved in this field.
The full name of WIFI is wireless fidelity, and the formal name of that is IEEE802.11b. WIFI technology is a wireless communication protocol and a short-range wireless communication technology, which can interconnect with personal computer and mobile terminals (PDA, mobile phones) wirelessly. Essentially, WIFI is a wireless network communication technology brand held by WIFI alliance and is mainly used to better the intercommunity among wireless network products based on IEEE802.11 standard.
WIFI has taken a place in the smart home field as well. When one is at home or in the office, one can control home devices by using simple controllers through WIFI technology. For example, one can control lighting system, adjust the shade of lights, open the door and window, and turn on household appliances through smart phones with WIFI function. Actually, most smart home products made by Philips, Sumsung, LG like smart bulbs adopt or support WIFI wireless communication technology. When one opens the smart phone or ipad which are connected with WIFI, one can control the home devices through smart home software easily.
However, the application of WIFI wireless communication technology in the single smart home device (smart bulbs, smart household appliances, smart washing machines) is very easy, but its application in the whole smart home system still exists problems that cannot be ignored. Safety problem is very crucial to smart home. Because WIFI adopts radio-frequency technique, sends and receives data through air, and transmit data signals through wireless radio wave, and therefore, packets can be tested or received by outside world in the process of transmission. Information security is a hidden trouble – although data can be transmitted after encryption, they can also be decoded by hackers in the case of enough packets.
All the home users of WIFI know that decoding WIFI is very easy even without the help of professionals. One can download the crack software from the Internet, and once the wireless network is cracked, it means he can share whatever you have imperceptibly. Although the WIFI technology applied in the smart home is encrypted in a certain way, it is really trivial, compared with ZIGBEE and SMART ROOM (ZIGBEE HA standard) which adopts AES advanced encryption technology that is stronger than encryption methods adopted by Banks.
Before the realization of the interconnection among home devices, the single smart home product is a small smart system. The application of WIFI is small accordingly and even if it is attacked or cracked by hackers, it does not impact other systems. But, once it is used in the whole smart home system, the hazard of cracking can be deadly. According to the feedback of IO Active academy, an America security inspection company, hackers can easily crack the Belkin smart home devices based on WIFI technology, steal the login information in the video camera, know whether the owners at home through a thermostat, and smart TV also become the channel of strangers to peep the owner’s daily life. Therefore, smart home based on WIFI technology cannot ensure users’ security. If even the safe home environment cannot be realized, how can we talk about efficient, comfortable, convenient life?
Home is our safe haven and people value the importance of home security gradually. What’s more, security and protection system has become the most important part in the smart home system gradually. So, with its own advantages, WIFI wireless communication technology has covered globally and been applied widely, and also can be embedded in some smart home products. However, it will not make a difference in the application of the whole smart home system.
