After the 80s and 90s, we have gradually grown up. We are also constantly exposed to the convenient products brought by the continuous development of technology. After we own our own home, we will also consider using smart home equipment more when decorating. It is understood that the smart home equipment on the market today is nothing more than smart sockets, smart network management and other low-cost, The intelligent functions of low technology products are also irrelevant. There are few products that can truly achieve the intelligent management of thousands of household appliances. Hejia Technology aims to provide intelligent hardware products and software services suitable for all ages, and has launched an interactive terminal product - doorman. Today, let's take you to appreciate the function of the doorman.

Unpacking experience

This trial is only for the doorman's terminal. In addition to the terminal packaging box, USB power supply card holder is also included. The outer packaging of both products is white paper box packaging. The front of the doorman's packaging box has the front boot image of the doorman's terminal and the logo of Hejia Technology, while the USB power supply card holder packaging box has the logo of Hejia.

The doorman terminal is designed to replace the switch position in the home at the beginning of the design, and the accessories in the doorman terminal package are the power supply base mainly for replacing the switch position. The other is the master of the doorman terminal, a little black guy in all directions.

All the accessories provided by the doorman terminal are the power supply base for replacing the switch, USB power supply base, USB power supply line and USB power adapter. The doorman of the family has provided two sets of power supply equipment for the user, taking into account that the user whose home decoration does not meet the installation requirements uses USB power supply. However, it is better to use the power supply base of the replacement switch. In addition to not affecting the beauty of the home, you can also use the terminal to control one or two lights.

Product details

The doorman's display screen is a LCD touch screen. Although the doorman does not need a particularly high pixel display, the imaging effect of the LCD display screen is unsatisfactory. The doorman's size is 86 * 86 * 12mm, and its weight is 100g. As a doorman, the size of the LCD screen is sufficient.

There are three parts at the bottom of the doorman. The dual speakers on both sides are high fidelity D-speakers. The voice of calls, voice messages and ringing tones are particularly loud. The speaker design is somewhat special. Is there a card swiping port in the POS machine. The middle is the call mic, which is the hard demand of video call.

The video camera, 2M high-definition camera, automatic diagonal, automatic white balance, and automatic color correction are located above the front of the doorman terminal, which will not blur the image. Although the display effect of the LCD screen is not good, the camera effect is good. At the right edge is the sensor hole, which realizes the screen wake-up function through optical induction.

At the bottom of the back of the terminal is the power supply interface of the terminal. In addition to the power supply interface, there are fixed interfaces matching the two power supply bases. The plug in design is convenient for users to take at will. However, it should be noted that the power supply base will make a loud noise when plugging and unplugging the doorman during power supply.

The two types of power supply bases are black and matched with the terminal color, and contact type power supply. The back of the replacement switch type power supply base is a wire interface, and the input voltage is between 180V and 250V. The replacement type base can support two position switches at most. If it is more than two position switches, it is recommended not to replace them with doormen.

Product experience

The main interface of the doorman is only available for calendar, weather, message, setting and binding. Turning to the second page to enter the binding page will give the QR code and invitation code to bind the doorman to the account. The button style design of icons is also good, but there will be drift in the process of use, that is, when you press the function button above, you actually press the function button below. Hopes the manufacturer can solve this problem.

The UI design of the function interface is the same. The calendar interface displays the Gregorian calendar date, week, lunar calendar date and lunar calendar year when it is opened, as well as the solar term and the current day's yellow calendar. You must watch the yellow calendar when you go out in the future, and be careful not to look at women on the yellow calendar. The weather interface displays the weather, temperature, PM value of the day, as well as exercise suggestions and drying suggestions. The most commendable thing for the doorman is the voice broadcast. When encountering bad weather or new voice messages, there will be voice weather or voice broadcast during the non disturbing period.

In terms of local messages, all messages that have not been heard will be retained, but once heard, the last four messages will be deleted and retained. This seems not particularly convenient. What if the important messages are beyond the last four? It is recommended to keep all messages of the day and support manual deletion. The wifi of the setting page is cancelled, the system is restarted, the data is cleared, and the version is updated.

Trial experience

The smart housekeeper app of the family is a management app tailored for the doorman. You need to enter your mobile phone number and obtain a verification code in the login interface. However, I wonder why it doesn't support user registration here, probably to prevent others from controlling their home. However, once you log in, you don't need to log in again. It's better to increase your registration. Otherwise, it will be inconvenient for users who need to use the APP for multiple mobile phones?

The smart housekeeper app is mainly divided into three sections: home, doorman and me. The home section is the core function section of the app. In this section, the doorman and other smart devices of the family can be controlled by functions, mainly the light control and alarm function of combustible gas or gas. However, the two functions can only be used with the accessories produced by the family, The function of video monitoring is to use the doorman as a monitoring probe to watch the situation at home at any time. The doorman section is to send voice messages and video conversation requests with the family. I hope the waiting ring tone of this function can be replaced. Can you not use the outdated Hexuan ring tone.

It is very convenient to add a doorman. You can connect the doorman by pressing a button and then scanning the code. However, the response timeout always occurs. I don't know whether it is because the home network is not strong. In addition to code scanning connection, you can also bind the serial number and invitation code to the doorman. Double binding insurance is good. In the process of code scanning and binding, you need to manually select permissions. Permission allocation will determine whether the video monitoring function is used.  

The mobile terminal display of video monitoring is good, and the imaging effect is very good. The doorman display of the video call function is also OK, but during the connection process, the doorman has successfully established the connection, but the mobile terminal is still establishing the connection, and the asynchronous time is about 2s, which is not a major problem. However, I hope that the screen display after the connection can be well modified. It can imitate WeChat. The main screen is displayed in full screen, and the main screen and small screen can be switched by clicking. The software UI design is still not perfect.

Test part

I won't draw the circuit diagram for the key points of circuit modification. I can't understand it myself. Be sure to distinguish the zero live wire. If you want to use a plug, you should distinguish the zero live wire end of the plug. Plug N is the zero wire end, and port 6 of the doorman terminal is the live wire access port. It is OK to distinguish these. After connecting the circuit, let's see the effect.

Since the installation staff did not arrive at my home for installation before the report was submitted, I did a simple circuit simulation test here to simulate the effect of the doorman on the light control. In general, the whole simulation process was relatively smooth, and neither the fuse nor the doorman blew, hahaha. After the doorman is connected to the lamp circuit, a switch with a light sign will appear on the doorman terminal, as shown in the lower left corner of the figure above. When the light is turned on and off, the icon will change according to the state. It's still a good function for light control. It feels like a high-tech touch screen without the touch of a switch, which is very nice.

summary

In general, the doorman terminal is not perfect, and it needs to be used together with the smart devices for family outing to be effective. Since the switch cannot be removed and replaced in this use, the experience of replacing the switch power supply base was not provided. The idea of the doorman's function is very good. It's a little pity that we didn't use the smart switch of the family this time. Otherwise, it's a little exciting to think that you can remotely control the light in bed. However, the functions of the doorman are still relatively few at present, and the price of 880 is relatively high, especially those smart devices that need to be used together need to be purchased additionally, which is somewhat expensive. In the future, it is hoped that the doorman of the family can integrate all household appliances, and the future life will have the possibility of wireless.
