Qualitative change! -From mechanical door lock to intelligent door lock.

　　After the epidemic situation was controlled at the beginning of this year, I had the opportunity to replace the mechanical door lock at home with the smart door lock with green rice. If the change of things is divided into quantitative change and qualitative change, the smart door lock is undoubtedly qualitative change. The intelligent door lock has changed the traditional way of unlocking, and it is far superior to the traditional mechanical door lock in terms of convenience, safety and ease of use. At the same time, it has also received the unanimous affirmation from family members.

　　In the course of nearly half a year’s use, there is a little regret. Every time you go out, you need to lift and lock the door, which is different from the natural process of opening the door and pressing the handle down. It is easy to ignore the action of lifting and locking the door up, especially when you go out with children and the elderly and need to take care of children. I have experienced this situation personally several times. Sometimes I will go back and lock it when I think of it, and sometimes I simply forget it.

　　In fact, this problem may not be a problem. It was not until recently that Xiaomi introduced a fully automatic intelligent door lock that I found that this was the best way to solve the problem.

　　The future has come? —— From manual intelligent door lock to fully automatic intelligent door lock.

　　It is estimated that many people will be like me. I don’t know that smart door locks will be divided into manual and automatic. I think they are all automatic, but they are not. Intelligent door locks include: manual, semi-automatic and full-automatic. Manual intelligent door lock, like the green rice I mentioned earlier, adopts double quick horizontal handles, which pull up the door and press down to unlock it; The semi-automatic intelligent door lock adopts mechanical self-elastic push-pull, automatic locking and manual unlocking; Automatic intelligent door lock adopts automatic lock body push and pull, and automatically unlocks and locks.

　　This upgrade is Xiaomi’s fully automatic intelligent door lock, which can realize full automation of locking and unlocking. Then let me explain the specific performance of this door lock.

　　Open at the touch, close the door and lock it!

　　This may be the best summary of the automatic intelligent door lock! After the verification fingerprint passes, the lock tongue automatically retracts, the door can be opened without pressing the handle again, and it is automatically locked after closing, which also saves the easy-to-ignore lifting process.

　　▲ Open at a touch.

　　Actually, the whole process is very friendly, mainly in the following points:

　　1. Locking/unlocking is fast enough, and there is basically no hysteresis. This feeling is basically the same as the practical manual door lock unlocking speed, even faster, so there is no need to worry about waiting for locking/unlocking.

　　2.

　　The sound of automatic locking/unlocking is pleasant! If you like the mechanical feeling as much as I do, you can also find pleasure in the automatic opening/closing sound of the door lock. After I first installed the door lock, I repeatedly opened and closed the door to listen to the automatic rotation sound of the mechanical gear, which was really fun.

　　Simple appearance, better match!

　　Mijia automatic intelligent door lock adopts black bright panel, which has high integrity. The design is simple and generous. Personally, I prefer this simple design, which is clear at a glance and convenient for daily cleaning.

　　Mijia automatic intelligent door lock has a reasonable functional division. Like most intelligent door locks, you can know how to use it at a glance.

　　The difference is that because it is a fully automatic lock body, there is no need to use the door handle to pull up and down, so the lock body can be designed more compact in appearance. This was a surprise when I first got the courier. The package was small, so it was hard to think that it was a smart door lock.

　　Safe, more than a little!

　　A variety of unlocking methods

　　Like many smart door locks, Mijia automatic smart door locks provide seven unlocking methods, namely: fingerprint unlocking, password unlocking, temporary password unlocking, emergency key unlocking, mobile phone Bluetooth unlocking, HomeKit unlocking and NFC unlocking. Password unlocking includes long-term valid password, one-time temporary password and periodic temporary password, which adapts to different usage scenarios.

　　Double authentication, just for security.

　　In addition to the 7 unlocking methods mentioned above, you can also turn on double authentication in the "Mijia" APP. That is, two of the above six unlocking methods (except the emergency key) can be used at the same time to achieve unlocking. Double authentication is more secure, but the convenience of operation will be discounted.

　　Make sure that each user has at least two authentication methods before turning on double authentication.

　　Tips: If you turn on double authentication, you must set more than two unlocking methods for each user, otherwise you will forget the embarrassing scene of not being able to enter the home after setting the second unlocking method for your family like me.

　　"Mijia"&"Family" Dual Platform Support

　　Mijia automatic intelligent door lock adopts Mijia and Apple dual security chips, which supports HomeKit unlocking. After setting the lock body in Mijia APP, you can bind the lock body to iPhone Home, and you need to authorize it in Mijia before using Home to unlock it, so that you can control the switch of the door lock through iPhone or Siri, and at the same time, you can realize linkage with other HomeKit devices.

　　Intimidate fingerprints, call the police at the touch.

　　The duress fingerprint is set in the Mijia APP by setting a finger as duress fingerprint in advance. If you encounter special circumstances, you can use duress fingerprint to unlock the lock. At this time, you will call the preset emergency contact person to call the police.

　　Although this is a very special situation, it is also a form of ensuring safety if manufacturers can think of some bad results in advance and provide them to users.

　　Abnormal warning of door lock state

　　By placing sensors in the lock body, the state of the lock body can be quickly sensed. Abnormal door lock warning: including multiple trial and error warning, anti-pry warning, door left unlocked warning, door ajar warning and low battery warning. Among them, the left-unlocked door, trial and error, and the warning of not opening the door are all very easy to encounter in daily life, so you should have these functions when purchasing smart door locks.

　　All the above abnormal warnings can be told to the user through the "Mijia" APP by push notification, so that I can grasp the status of the door lock in the first time.

　　More security settings

　　In the official website of Mijia, you can see that there are ten kinds of security protection. In addition to the above, there are the following:

　　One-button protection: it needs to be implemented with intelligent gateway, which I have already introduced in the experience of green rice’s intelligent door lock, and I will not expand it here.

　　Resist the black box attack: prevent the use of electromagnetic interference to open the door.

　　Child lock design: by detecting the fingerprint area and the touch area behind the armrest, the door can be opened only when it is satisfied, so as to prevent children from touching the door by mistake.

　　Electronic anti-lock: Although it has the anti-lock function, it is a bit unexpected to use the same lock tongue, which I will mention at the end of the article.

　　APP grasps the door lock status in real time.

　　The "Mijia" APP not only realizes one-stop management, but also is a terminal for all kinds of reminders, so that you can always keep track of the door lock, so that you can feel more at ease when you go out.

　　In a word, compared with traditional mechanical door locks, smart door locks have nothing to worry about in terms of safety.

　　Intelligent linkage, let the family know you better.

　　The realization of intelligent linkage needs the hardware support of intelligent gateway and other intelligent devices, that is to say, the hardware of intelligent devices is already available at home. Taking the gateway as the center, the linkage of different intelligent devices is realized by sending the door lock status to the gateway.

　　Take my home as an example. Intelligent devices include: intelligent gateway, Xiaoai speaker Pro, Zigbe smart plug, Aqara light bulb, air conditioning companion, rice home appliance fan, smart rice humidifier, rice home sweeping robot and other devices. Different functions can be realized through the combination of different devices.

　　Warm greetings: smart door lock+small love speaker Pro, different users unlock and play the set content.

　　Cleaning away from home: intelligent door lock+sweeping robot. It should be noted that if there are people at home, it may not be possible to just set it to clean away from home. It can be set to start the sweeping robot when the protection mode is turned on.

　　Power off when leaving home: smart door lock +Aqara light bulb+smart plug, similarly turn off the lights, power supply, air conditioner, etc. when it is set to the protection mode.

　　There are many ways to play intelligent linkage, which can be set according to your actual living habits. Thinking more and doing more will have unexpected effects.

　　Regretful place

　　During the period of using Mijia smart door lock, I am very satisfied with the stability and convenience, but there is one thing I think can be improved: anti-lock.

　　The anti-lock function of Mijia automatic intelligent door lock is electronic anti-lock, which is very consistent with the automatic identity. However, there is only one set of locking tongue of the door lock, that is to say, only the electronic control of the door lock is realized when the door lock is locked, and there is no independent locking tongue, which is not as safe as the independent locking tongue to some extent, which may be related to the positioning of the lock body and the price.

　　However, the defects are not hidden. On the whole, Mijia automatic smart door lock is a smart door lock that is very suitable for home use! The convenience brought by smart door locks is only known when you use them!

　　The future is just around the corner

　　Xiaomi’s UWB technology video realizes centimeter-level positioning of smart home devices, making smart life simpler and more practical. Starting from the Mijia smart suit, most of the smart devices at home are Mijia or support Mijia ecological products, and Xiaomi plays an increasingly important role in the whole smart home ecology.

　　It is worth mentioning that the smart door lock at the end of the video automatically detects the mobile phone signal, and the process of identifying unlocking is really handsome, and this door lock is Xiaomi’s automatic smart door lock.

　　From manual to semi-automatic, and then to full-automatic, the intelligent door lock is obviously not as fast as mechanical door lock and has a large span and obvious perception. But it is the automatic intelligent door lock that can realize the real "intelligent door opening".

　　Technology is changing life at a rapid speed, as the end of the film says, "The future is just around the corner"!
