In 2019, I bought a first-generation wifi version of a smart socket. Later, because it was useless, I gave it to people in the same community. Now my two-wheeled electric vehicle needs a socket that can accurately control the switch and measure the amount of electricity, so I again Turn your attention to the Mijia smart socket. At the beginning, I searched for some videos and watched some evaluations at station B. I didn’t think much about placing an order for the Mijia Smart Socket 2nd Generation Smart Gateway Edition, but the next day I surfed the Internet and accidentally discovered the third-generation product that was just released. . Official website product page https://www.mi.com/shop/buy/detail?product_id=16421 I quickly applied for a refund and placed an order for 3 generations without hesitation. Because the third generation has a charging protection function .
You can see the article published by IT Home on 2022-08-23: Xiaomi Mijia Smart Socket 3 is on the shelves: supports remote control / power statistics, priced at 59 yuan https://www.ithome.com/0/636/605. htm
First experience last night and felt good. The specification of my lead-acid battery is 60V 20Ah, it is 1.2 kWh when fully charged, and the output power of the charger is 60V 2.8A.

It can be seen that the 3rd generation has a lot more functions than the 2nd generation smart gateway version. The local timer allows you to use the countdown function even when the network is disconnected. The power consumption reminder is also very useful. For my usage scenario, the practicality of the charging protection function is max. As for other features like child locks, something is better than nothing, and someone will always need it. It is worth noting that the 3rd generation does not have the 2nd generation smart gateway, but this smart gateway is not a smart mesh gateway, which is not attractive enough to me. In the end, of course, I chose the freshly released third generation.
This article will show you the detailed setting interface of this socket and see what functions it has.
This is the product picture. In fact, I feel that the small things are very delicate and feel very good. It has a heavy sense of weight. I have not photographed the real thing.

In the main interface during initial use, the background color of the socket icon is blue to represent the open state of the switch, and gray to represent the closed state. It can be seen that the actual power is larger than the output power of the charger, and a rough calculation can calculate that the conversion efficiency of the original charger of my little electric donkey is 81.6%.
This charging protection function is very suitable for charging scenarios of mobile phones, charging treasures, batteries, and two-wheeled electric vehicles. I set it below 6w for 8 minutes to automatically turn off the socket and stop charging.
This condition was triggered at 06:45 this morning and the socket was automatically turned off, which is very suitable for battery cars to prevent overcharging.
I have screenshots of all his functions.

As mentioned above, my lead-acid battery is 1.2 kWh, and the following is the charging data.
A total of 1.18 kWh is consumed, which is pretty accurate! A bit of a surprise, preventing overcharging helps preserve battery life. “anti aging”.
On August 31, the electricity consumption was 0.27 kWh (before 24:00 last night)
September 1st 0.91 degrees (after 0 o’clock today)
Finally, I want to say that it is really fragrant. These smart small pieces of Mijia have done a good job. 🙂
