MerossThreadSmartPresenceSensor,MS605

• Upgraded Presence Sensor with Thread:The MS605 adopts the latest Matter over Thread protocol with a cutting-edge Nordic chipset, powered by a long-lasting battery for flexible installation. Combining millimetre-wave radar and infrared motion detection, it can precisely sense subtle movements and human presence. Equipped with a real-time light sensor, it monitors ambient brightness and instantly reports changes to the Matter platform.
• Meross Hub-Free:Quick Bluetooth setup via the Meross app lets you easily achieve fine-grained, personalized device configuration, then connects through a compatible Thread Border Router to run locally and privately on your preferred platform (Alexa, Apple Home, Home Assistant etc.) no Meross hub or ongoing app use required.
• All-Scenario Flexible Mounting:With a 90 foldable + 360 rotatable stand, it can be installed on ceilings, walls, or corners as you wish. Featuring a 3-year lithium battery (CR123A, included) and IP67 waterproof rating, it operates reliably from -20C to +60C ready to use out of the box. Whether in humid bathrooms, cold basements, or hot attics, it performs flawlessly. Detects motion up to 6m and presence precisely within 4m, ideal for rooms of all sizes, like studies or bedrooms.
• 3-in-1 Smart Sensing Technology:Goodbye to false triggers from traditional single sensors! With triple detection technology radar, infrared, and light sensing it ensures more accurate and reliable results.
  – Millimetre-wave radar detects subtle micro-movements (e.g., breast movements while breathing).
  – Infrared sensor filters non-heat motion like curtains or robot vacuums.
  – Light sensor enables smart lighting control (note: Alexa currently doesnt support the light sensor).
• Whole-Home Smart Integration:Supports Matter over Thread direct connection to Apple HomeKit, Alexa, Google Home, SmartThings, and Home Assistant no extra hub (such as Meross MSH450) or 2.4GHz Wi-Fi required. Experience low-latency local control: night 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 it works even without the internet.
• Three-Zone Smart Scene Control:Divide the detection range into three customizable zones in the Meross App. Each zone can independently set presence/absence conditions and appears as separate sensors on third-party platforms for advanced automation. Examples:Study: 5m main light on; 2.4m desk lamp on. Bathroom: 6m night light on; 4m bathroom light on; 1.6m for 1s mirror light on. Smart detection, precise presence sensing, flexible installation all in one!
