[High Precision AI-Driven Presence Sensor] The Meross MS605 Human Presence Sensor uses static detection and adaptive AI to keep lights on while you're sitting still, solving the 'no motion = lights off' problem of traditional motion sensors. Built with 3-in-1 mmWave & PIR & light sensors, powered by continuous AI space learning to minimize false triggers. 【Note: Update firmware in Meross app for a stable Alexa direct control.】
[Seamless Matter Integration] Discover the power of Matter! MS605 HomeKit motion sensor supports Matter over Thread for direct connection to Home Assistant, Alexa, Google, and HomeKit. Note: To add the MS605 Wi-Fi presence sensor to a third platform Matter-enabled app, ensure you have a hub that supports both Matter and Thread. *Pair with the hub to enable remote access.
[Battery-powered and All-Scenario Flexible Mounting] This wireless presence sensor equipped with a 90° foldable + 360° rotatable stand, so the MS605 Matter motion sensor can be installed on ceilings, walls, or corners as you wish. Featuring a 3-year battery (CR123A, included) — ready to use out of the box. Whether in humid bathrooms, cold basements, or hot attics, it performs flawlessly. Ideal for outdoor driveway security detection with IP67 waterproof rating.
[Privacy Protection and Low Latency Local Control] MS605 mmwave presence sensor control lights turn on automatically when you get up, and lights and AC activate instantly when you return home. Matter local control means higher security — your data stays private, and this smart motion sensor works even without the internet.
[Personalize Your Smart Home] with advanced app automation, custom sensitivity, and multi-sensor zoning. Divide the detection range into three customizable zones in the Meross App with this Matter smart home presence sensor. Each zone can independently set presence/absence conditions and appears as separate sensors on third-party platforms for advanced automation. Examples: Bathroom: 6m → night light on; 4m → bathroom light on.

Pairing with Apple Home (Matter) fails with the message "Device could not be found." What should I do?

1.Long-press the button on the MS605 for 5 secondsuntil the LED starts flashing orange.

2.The orange blinking confirms Matter pairing mode is active.

3.Scan the Matter code again in Apple Home.

4.The device should now be discoverable.
Can I still use the Meross App after connecting the device to a Home Assistant via Matter?

Yes. You can still connect via the Meross App using Bluetooth. Bluetooth is awakened by:

*Pressing the physical button on the sensor.

*A state change from "Vacant" to "Occupied"(e.g., someone walking past).
Are all advanced settings only configurable in the Meross App?

es. Advanced sensing features such as**Space Learning, sensitivity

adjustments, zone setup, and custom automation logic**can**only**be configured in the Meross App. The Matter protocol does not expose these configuration options.
Are the settings I configure in the Meross App saved to the device itself?

Yes. All settings(zones, sensitivity, logic, etc) are permanently saved locally on the MS605 sensor. Once saved, these optimizations continue to work automatically when the device is connected to Apple Home, Google Home, Alexa, Home Assistant.
