AI-Driven Presence Sensing for Realistic Room Awareness

The Meross MS605 blends static detection with adaptive AI to keep lights and climate responsive as you move through a space. By combining three sensing modalities — mmWave radar, PIR, and ambient light — the sensor minimizes false triggers while staying vigilant when you need illumination or occupancy data.

What makes it smart

  • High precision AI driven presence sensing with multi-sensor fusion
  • Battery powered with long life and flexible mounting options
  • Rugged IP67 design for damp spaces and outdoor use

Matter, Thread, and platform compatibility

MS605 supports Matter over Thread, enabling direct connections to HomeKit, Home Assistant, Alexa, Google, and compatible Matter hubs. For third party Matter apps, pairing through a hub that supports both Matter and Thread is recommended.

Fast, private control with local processing

Local control keeps responses quick and data private. Lights can turn on as you rise, and energy-saving actions can react immediately when you return home, without requiring cloud access.

Flexible mounting for real-world spaces

The unit ships with a 90° foldable stand and a 360° rotatable head, so you can mount on ceilings, walls, or corners. A CR123A battery is included, delivering about three years of typical use.

Zones and automation you can trust

In the Meross app you can define three customizable zones with separate presence/absence logic. Each zone appears as a separate sensor in supported platforms, enabling tailored automation (for example, night light in a bathroom, while a hallway stays off).

What’s in the box

  • MS605 presence sensor
  • CR123A battery (3 year life)
  • Mounting hardware and quick start guide

Note: Update the firmware in the Meross app to ensure stable Alexa direct control.
