Xiaomi has opened crowdfunding for a new smart plug that makes it easy to turn regular appliances into smart ones.

The Xiaomi Smart Socket 4 is listed on Xiaomi Youpin for 49 yuan (around $7), with the campaign running until September 16 at 09:59:59. The regular price will be 59 yuan. It’s a compact plug aimed at people who simply want remote control and energy tracking for older devices around the house.

It connects straight over Wi-Fi 6 (2.4 GHz only), so you don’t need a separate gateway. Combined MU-MIMO and OFDMA tech should keep things stable even when you’ve got a bunch of devices online at once, commands don’t have to sit in a queue. Basically, you can make ordinary appliances respond through your phone instead of walking over to flip a switch.

The socket works with Xiaomi’s HyperOS Smart Connect system and shows up in the Mi Home app. From there you can control it alongside your other devices and set up custom automation scenes that match your daily routine. It also has a high-precision metering chip that gives you clear charts for power use, so you can check daily, weekly, or monthly stats whenever you want.

Timer and countdown functions run locally on the plug itself. That means scheduled tasks keep working even if the internet drops, and power cuts off automatically when the time is up. You can also set the physical button so a double-press starts a countdown and shuts everything off without opening the app.

A few practical upgrades stand out: the body is smaller (52 × 41 × 57.6 mm), so it blocks fewer neighboring outlets on a power strip. It uses the updated Chinese national standard plugs with insulated sleeves for better safety. There’s also protection against overheating, surges, over-current/overload, plus charging safeguards and a child lock. In the app you can set power limits anywhere from 100 W to 2500 W.
