Xiaomi has unveiled the Mijia Smart Bathroom Heater P1 Human Sensing Edition, a ceiling-mounted heater, light, and exhaust fan combo that uses 24GHz radar instead of basic motion sensors to track whether someone is actually in the room.
The ceiling-mounted unit folds three functions into one, and the radar sits at the center of how all three behave. Walk in, and the lights and fan respond. Stay still, and the system still knows you’re there. Walk out, and everything shuts down on its own. Xiaomi has made the detection range and sensitivity adjustable too, a necessary touch given how easily radar can misfire and switch things on just because someone walked past an open bathroom door.
The heating side runs on a 3,000W graphene heating element paired with variable frequency control, so instead of running at full power the whole time, it adjusts output to hold a set temperature. An oscillating louver swings between 60 and 90 degrees to push that warm air down toward the floor rather than letting it pool near the ceiling, and dual DC motors let the heater and exhaust fan run at the same time without one fighting the other for power. The exhaust itself is rated to move around 259 cubic meters of air per hour, a respectable extraction for a single ceiling unit.
Lighting is handled by a retractable panel that sits flush with the ceiling when not in use, putting out up to 1,500 lumens across a color temperature range of 3,000K to 6,200K, plus a dedicated night light mode for anyone stumbling in at 2am who doesn’t want the full brightness.
Everything ties into the Mi Home app and Xiaomi’s HyperOS ecosystem for scheduling and voice control, and the unit ships with an IPX4 water-resistant wireless wall switch that fits into a standard 86mm electrical box, meaning installers don’t need to run new wiring to add a physical control point.
The Mijia Smart Bathroom Heater P1 Human Sensing Edition enters crowdfunding in China next week priced at 999 yuan, about $148. Xiaomi has not indicated whether the device will see release outside China.
I’ve been obsessed with tech for as long as I can remember, so much so that I’ve become the unofficial “tech support” for my entire family. Whether it’s fixing gadgets, explaining specs, or recommending the best buys, I love breaking down tech for everyday people. That passion led me to writing about tech. When I’m not testing gadgets or writing reviews, you’ll probably find me hiking or doom-scrolling car listings (still hunting for my first ride, wish me luck, lol).
