Xiaomi Smart Switch 2 Pro 2026: $17, No Neutral Wire Needed - Memeburn
TL;DR
- Crowdfunding prices start at CNY 114 (~17) for one button and reach CNY 152(~23) for three.
- It works with or without a neutral wire and picks the right mode by itself at power-on.
- The 3.5mm panel is far slimmer than September's 11mm Smart Switch 2, which starts at ~$10.
- It's rated for 10A and 2,200W on China's 220V power, or about 1,200W on US 120V circuits.
- You need a Xiaomi Bluetooth Mesh gateway for app control, and it's sold in China only for now.
Xiaomi just opened crowdfunding for the Smart Switch 2 Pro, a wall light switch that starts at CNY 114 (~$17), sits just 3.5mm off the wall, and works in older homes that lack a neutral wire, the missing cable that blocks most people from installing a smart switch. Smart switches are one of the cheapest ways to make a home “smart,” because they upgrade every light on a circuit at once, and Xiaomi now sells two generations of them for less than many single smart bulbs. Here’s what the Smart Switch 2 Pro does, what’s actually new, and the catches you should know before you get excited.
What Xiaomi Launched, and What It Costs
The Smart Switch 2 Pro comes in three versions, all sized for China’s standard 86-type wall box, the square box behind most switches in Chinese homes:
It’s on Xiaomi Youpin, the company’s Chinese crowdfunding and lifestyle store, in two colors. Crowdfunding prices are usually Xiaomi’s lowest, and some listings already show a regular price of around CNY 149 (~$22), so expect the price to rise once early-bird stock runs out.
First, What Does a Smart Switch Actually Do?
A smart switch replaces the normal light switch on your wall. It still works like a regular switch when you press it. But it’s also connected to your phone, so you can turn lights on and off from an app, by voice, on a schedule, or automatically when something else happens in your home.
Here’s why that often beats buying smart bulbs, the other popular option:
- One switch, many lights. A switch controls every bulb on that circuit. A living room with four ceiling lights needs one switch, not four smart bulbs.
- Your family can still use the wall. With smart bulbs, flipping the normal switch off cuts power to the bulbs, and the app can’t turn them back on. With a smart switch, the wall button and the app always agree.
- Any bulb works. You can keep using the cheap LED bulbs you already own.
The downside is installation. You’re replacing something wired into your walls, which in many countries legally requires an electrician. That’s where the neutral wire problem comes in.
The Neutral-Wire Problem, Explained Simply
A normal light switch is just a gap in a wire. Press it, and the gap closes so electricity flows to the bulb. That’s why many switch boxes only have a live wire going in and out. There’s no need for anything else.
A smart switch is different. It has a tiny radio and chip inside that need power all the time, even when the light is off, so they can listen for commands from your phone. Most smart switches get that constant power from a neutral wire, a return cable that completes the circuit. In lots of older homes in the US, UK, and Asia, that neutral wire simply isn’t in the switch box. Adding one can mean opening walls.
Xiaomi’s fix is a single live-wire mode. The switch sips a tiny amount of power through the light itself, even when the light is off, which is enough to keep its radio running. The Smart Switch 2 Pro detects whether your box has a neutral wire when it powers on and picks the right mode by itself, with no settings to flip.
There’s a known catch with this approach. That trickle of power can make some low-wattage LED bulbs flicker or glow faintly when they should be off. Xiaomi says its new generation is tuned to reduce LED flicker, and we’d still test it with your exact bulbs before swapping every switch in the house. In the West, no-neutral smart switches exist too, but rival workarounds typically cost $50 to $70 per switch, several times Xiaomi’s price.
Smart Switch 2 Pro vs Smart Switch 2: What the Extra $7 Buys
Xiaomi launched the regular Smart Switch 2 just six weeks ago, in early September. Both share the same brains, so the Pro is mostly about looks and build quality.
The 3.5mm panel is the headline. Most wall switches stick out about a centimeter, so this one sits almost flush, like a thin glass tile. AG glass has a matte, anti-glare finish, and the AF (anti-fingerprint) coating helps it resist oil and smudges, which matters on something you touch every day.
A relay is the tiny mechanical part that actually switches the power on and off. Xiaomi says it’s rated for a million presses, which works out to more than 90 years at 30 presses a day.
Our take: the Pro is worth the extra money if the switch is in a spot people see, like a living room or a hallway. For a garage or storage room, the cheaper Smart Switch 2 does the same job.
Automation: Where It Gets Useful
This is what you’re really paying for. Some examples Xiaomi gives:
- Lights on when you get home: pair it with a Xiaomi smart lock, and the hallway light can turn on when the door unlocks.
- One “leaving home” button: a single press turns off every light, opens or closes the curtains, and starts a robot vacuum.
- Wireless mode: any button can stop controlling its own light and act as a remote for other devices, like an air purifier or vacuum.
On dual and triple versions, the Mi Home app can also reassign which button controls which light. That sounds minor, but it’s a real fix for homes where an electrician wired things in a confusing order.
Control works three ways: press the button, use the Mi Home app, or ask Xiao Ai, Xiaomi’s Chinese voice assistant. Xiaomi says its Mesh 2.0 wireless module responds 50% faster than before.
Here’s the hidden cost. App and voice control need a Bluetooth Mesh gateway, a hub that links the switch to your Wi-Fi. Many Xiaomi smart speakers and hubs act as one, but if you don’t own any Xiaomi gear yet, budget for it. Without a gateway, the switch still works as a normal switch, and you lose the smart part.
2,200W and 10A: What You Can Safely Run
The switch is rated for 10A (amps) and 2,200W (watts), with built-in protection against overheating and overloading.
Watts measure how much power a device uses. Amps measure how much current flows through the wire. The two are linked by your home’s voltage. China uses 220V, and 10A at 220V equals 2,200W. In the US, homes run at 120V, so the same 10A limit would allow only about 1,200W.
In practice, that’s plenty for lights. Even a large room full of LED bulbs rarely draws more than 100W to 200W. But don’t use a light switch like this to control a space heater, kettle or air conditioner. Those can pull far more power and belong on circuits built for them.
Can You Buy the Xiaomi Smart Switch 2 Pro Outside China?
Not easily, and we wouldn’t try to import one. Here’s why:
- It’s China-only for now. It’s listed on Youpin, with no global launch date. Xiaomi often takes a year or more to bring smart home gear abroad, if it does at all.
- It’s built for Chinese wall boxes. The square 86-type box doesn’t match the rectangular boxes common in the US or the round ones used across much of Europe.
- Software is set up for China. Xiao Ai speaks Chinese, and some Mi Home features only work on the China server region.
- Wiring rules. In many countries, installing an imported switch without the right safety certification can break electrical codes and even affect home insurance.
If you live outside China and want a cheaper smart home, look for locally certified switches from brands that support Matter, an industry standard that lets smart home gear from different brands work together.
The Xiaomi Smart Switch 2 Pro is a clever, cheap answer to the most annoying problem in smart homes: old wiring. A sub-$20 switch that needs no neutral wire, looks like a sheet of glass, and triggers whole-home routines is exactly the kind of product that makes smart homes normal rather than nerdy.
For buyers in China, it’s an easy upgrade, as long as you already own a Xiaomi gateway or plan to buy one. For everyone else, it’s a preview. Xiaomi is showing how cheap a good smart switch can be, at a time when Apple’s first smart home line costs $1,740 for the full set. We’d expect Western brands to feel that pressure on price, even if this exact switch never reaches your local store.
FAQs
Does Apple make smart home devices like locks and thermostats?
Not directly, but it helped design some. Apple worked with LG on a smart lock, doorbell, and thermostat built to work closely with the Home app, which shows how hard Apple is now pushing into the smart home.
Does Xiaomi make its own chips?
Yes, for its phones. Xiaomi designs its own XRING processors, and the XRING O3 chip broke the 4GHz barrier, putting it in the same race as Apple and Qualcomm.
Can a portable 5G router replace home internet?
For many small homes and renters, yes, if 5G coverage is strong where you live. ZTE’s $90 portable 5G Wi-Fi hotspot is one of the cheapest ways to try it before cancelling a fixed-line plan.
Is Xiaomi selling more of its products outside China?
Yes, especially phones. Its latest flagship is going global as the Xiaomi 18 Pro, though smart home gear usually follows months or years later, and some never leaves China.
Do smart home cameras know who’s at the door?
Some do, using face recognition. Apple’s $299 HomeView recognizes faces of people you’ve tagged in your photo library, which is convenient but raises fair privacy questions about who gets scanned.
