Xiaomi’s new Mijia ducted air conditioner uses mmWave presence sensing to steer airflow and cut standby power

Xiaomi has opened pre-orders in China for the Mijia Central Air Conditioning Duct-type Unit with Motion-sensing Airflow 4 HP (Dual Outlets), a smart, ducted system aimed at whole-home installations.

The headline feature is built-in mmWave presence sensing designed to adjust airflow based on where people are in a room.

According to Xiaomi’s product listing, the indoor unit uses a triple-row heat-exchanger design, a layout the company says improves heat transfer for both cooling and heating.

Xiaomi positions the unit as a higher-end option within its Mijia smart home lineup, with dual air outlets intended to better distribute air in larger spaces.

How motion-sensing airflow works?

The integrated mmWave sensor can detect human presence and trigger automation rules that change how the system behaves. Users can configure the air to blow toward occupants for faster comfort or away from them to reduce direct drafts.

Xiaomi also markets an energy-saving angle: when the sensor detects no one in the space, the system can be set to turn off automatically. That capability targets common waste in air-conditioned homes, where units are left running in empty rooms.

Efficiency rating and smart controls

Xiaomi lists an Annual Performance Factor of 4.62 for the unit, indicating an efficiency-focused design for its class. As with other recent Mijia appliances, it supports HyperOS Connect, enabling remote control through Xiaomi’s app and voice control through compatible assistants.

The company says the system can be expanded with optional accessories such as a Smart Air Management Panel, a Fresh Air module, and a MIFD health filter. Those add-ons are pitched as modular upgrades for monitoring, ventilation, and filtration needs.

Price and wider availability

In China, the ducted air conditioner is priced at CNY 8 999 for pre-order, which is roughly $1 300 at current exchange rates.

Xiaomi already sells some smart air conditioners in parts of Europe, but it has not confirmed whether this specific ducted model will launch outside China.

For now, the release underlines Xiaomi’s broader push to combine sensors and automation with major home appliances, especially where comfort and energy use can be fine-tuned. Whether motion-aware airflow becomes a mainstream feature may depend on how quickly Xiaomi scales these systems to more markets.
