These counts describe the available data, not a quality score. More features do not automatically make a better device.
Consider your setup
Confirm which features appear in Apple Home and whether extra hardware or a subscription is needed for your intended use.
Inspect the specificationsConsider your setup
Confirm the exact device type and the features exposed in your chosen platform. Protocol support does not establish feature parity across apps.
Inspect the specificationsYour priorities, side by side
Mark the specifications you care about. Open manufacturer sources for verification scope; fields without citations remain catalog data. Expand notes for other qualifications.

Presence and absence state changes are pushed to the Matter platform, which is what raises the alert or runs the automation.
5.8GHz Microwave Radar
Meross states the sensor needs no 2.4GHz Wi-Fi: it runs on Matter over Thread and the spec sheet lists Bluetooth as its only other radio. The word Wi-Fi in some marketplace titles is keyword stuffing, not a radio this model has.
Bluetooth 4.3, used only to pair and configure the sensor from the Meross app; the device then reports over Thread.
Matter over Thread on a Nordic chipset. Meross states a hub that supports both Matter and Thread is required to add it to a third-party platform.
The 6m range can be split into three zones in the Meross app, each with its own presence and absence conditions, and each appears as a separate sensor on third-party platforms so automations can key off distance. An AI auto-adjust pass filters interference from fans and air conditioners. | Automations built inside the Meross app itself need a Meross hub, which Meross says is still in development.
The sensor splits its range into distance zones and reports each one as its own occupancy sensor. It does not count people or track individuals inside a zone.
Meross specifies motion detection up to 6m and precise static presence within 4m.
A battery-powered Thread end device, so it neither speaks Zigbee nor repeats traffic for other devices.
Via Matter, through an Echo that acts as a Matter and Thread border router. Meross notes Alexa does not currently surface the sensor's light reading, only its presence state.
Via Matter, with a HomePod or Apple TV acting as the Thread border router.
SONOFF lists this model among the Zigbee devices its Matter bridges (Zigbee Bridge Ultra, iHost, NSPanel Pro) publish to Matter, which is how it reaches the Apple Home app. Apple Home has no Zigbee radio of its own.
Via Matter. Meross lists Google Home among the platforms the sensor connects to directly over Matter.
Via Matter. Home Assistant is a certified Matter controller, and Meross names it as a supported platform for this sensor.
The sensor supports Matter over Thread.
Meross Presence Sensor MS605 manufacturer product page →Matter-over-Thread use requires a compatible controller and Thread border router. Light-sensor exposure depends on the ecosystem.
Document check only; not a hands-on test or verification of every regional or firmware variant.
Certified under the Matter 1.4 specification, with both the occupancy sensor and the light sensor exposed to Matter platforms.
The device is not Matter itself: SONOFF lists it among the Zigbee models its Matter bridges (Zigbee Bridge Ultra, iHost, NSPanel Pro) republish into Matter.
Via Matter. Meross lists SmartThings, and notes that it exposes a single presence sensor there rather than the three zones other platforms see.
Battery powered by a single CR123A lithium cell (included), rated by Meross for 3 years. There is no wired or USB power option.
A light sensor is included.

Built-in ambient light sensor, reported live to the Matter platform as an illuminance reading for lux-aware lighting automations.
Radar and infrared sensing detect people.

24GHz mmWave Doppler radar paired with a PIR infrared sensor, so it holds a room occupied on breathing-level movement while the infrared side filters heatless motion such as curtains or a robot vacuum.
