Love the performance, not the wiring
I’ve been using the Meross Matter Human Presence Sensor (MS600) for a little while now, and overall I’m happy with it. The combination of PIR and mmWave radar makes presence detection much more reliable than a basic motion sensor, it doesn’t turn the lights off just because I’m sitting still at my desk. Setup through Meross app and Matter was easy, and it integrates nicely with my Homekit system.The light sensor is a nice bonus, and the adjustable base makes it easy to aim exactly where I want. Once it’s in place, it does exactly what I need, fast detection when I enter and stable presence sensing while I’m in the room.That said, I really wish Meross had made a battery-powered version. The sensor only works when plugged in, and the included cable is a bit messy, not looking good when connecting, and definitely limits where I can mount it. There were a couple of ideal spots in my home where I just couldn’t install it because there was no outlet nearby. A clean, wireless option would make this sensor close to perfect.Overall, I’m pleased with the performance and accuracy, but I’m hoping a future generation ditches the power cord or at least offers a battery option for more flexible placement.

Endless Possibilities for Smarter Automations – Great Product!
I’ve been using the meross 3-in-1 presence sensor for a few weeks now, and it’s easily one of the most reliable sensors I’ve added to my smart home. The combination of PIR and mmWave makes a noticeable difference—unlike standard motion sensors, this one can actually tell when someone is still in the room even if they’re not moving around. That alone solved a lot of the false “room is empty” automations I used to run into. I also love that it integrates with my Apple Homekit to allow me to use SIRI to create control scenarios.Setup was straightforward. I’m using it across multiple ecosystems, and the Matter support really does make it feel more stable and responsive. I’ve had zero issues with lag or dropped connections. The adjustable mount is also more useful than I expected; it made it easy to position the sensor exactly where I needed it without drilling a bunch of holes.Presence detection range and motion detection are both solid. It picks me up consistently from across the room but hasn’t been triggered by my dog since I installed the pet shield. The built-in light sensor has been great for more refined lighting automations as well.One specific scenario I am using the sensor for is in my home music studio: mostly because I’m notoriously bad about leaving gear powered on when I walk away. Some of my equipment is expensive and I don’t want it running for hours just because I forgot to flip a switch. At the same time, I didn’t want a setup that kills the power the moment I stop moving—sometimes I’m sitting perfectly still while editing audio, or I step out for a minute to grab coffee. With this sensor, I was able to set up an automation that checks whether the room has been empty for 30 minutes and then does a soft, orderly shutdown of everything. The combination of PIR and presence detection has been accurate enough that it never shuts things off while I’m quietly working, but it also hasn’t missed a single time when I truly left the room. It’s solved a problem I’ve had for years without me needing to babysit anything.Overall, this sensor does exactly what it promises and fills a gap that basic motion sensors can’t. If you’re building out a smart home and want more accurate automations, this is a great choice.

Presence Sensor Like no others.
Just picked up the Meross Matter Human Presence Sensor (the 3-in-1 with mmWave radar + PIR + light sensor) and wow, this little thing is impressive for the price.Install was literally 5 minutes. Plug in via USB-C (it comes with a decent cable), and you’re done. No hub needed because it’s native Matter – added it straight to HomeKit and Home Assistant with zero fuss.The mmWave radar is the star here. Unlike cheap PIR sensors that only catch you when you’re already moving, this one actually detects presence – I stuck it in my office and it knows I’m sitting at the desk even if I’m just typing or reading. No more lights turning off mid-Zoom call. Sensitivity and hold-time are fully adjustable in the Meross app, and because it’s Matter the settings sync everywhere.Light sensor works great too – I have it automating “occupied but dark → turn on lamp” and it’s spot-on.The Meross app is still meh (same clunky channel-naming issues as their other stuff), but since I only used it for initial setup and now run everything in Apple Home + HA, I barely touch it.For ~$30 it’s ridiculous value. If you’ve been disappointed by regular motion sensors cutting out while you’re still in the room, grab this one. Finally, proper presence detection that just works. 5 stars easy!

Frustrating Setup and Useless Performance
This Melross sensor has been a complete disappointment. I spent over two hours trying to install it, and despite repeated attempts, it simply does not work properly. The installation process was one of the most difficult I’ve experienced with any smart home device. While it now detects motion, it fails to trigger any action, and connecting it with Alexa has been nothing short of a nightmare.I have extensive experience setting up smart devices, but this was by far one of the worst. I was misled by overly positive YouTube videos and glowing reviews suggesting that installation was easy. In hindsight, I should have paid more attention to the few negative reviews that described the exact same issues I’m now facing.My honest recommendation: avoid this product entirely. It’s not worth the time, frustration, or effort.

it’s been a fantastic addition to my smart home setup. The sensor is incredibly responsive, detecting motion accurately and triggering my connected devices without delay. Setup was a breeze through the Meross app, and it integrates seamlessly with my existing smart home ecosystem (works great with HomeKit!). The build quality feels solid, and the compact design blends well into any room. I also appreciate the adjustable sensitivity settings, which let me customize it to my needs. Highly recommend this sensor for anyone looking to automate their home lighting or security!

Lo he estado probando durante mas de 1 semana y aquí están mis conclusiones:Pros:- La detección automática de movimiento/presencia me permite que al entrar en una habitación se encienda la luz sin ningún mando: una comodidad muy apreciable en mi día a día.- Muy buena integración con Amazon Alexa: desde la app de Alexa configuré que, al detectar presencia, se active un enchufe inteligente que tengo conectado a la lampara. Funciona fluido y sin controles complicados.- El sensor de luz ambiental (que regula la automatización según el nivel de luminosidad) añade un plus que evita que la luz se encienda cuando ya hay luz natural abundante.- Instalación sencilla: en mi caso fue rápido conectarlo al enchufe/interruptor y a la red WiFi. No tuve que hacer demasiados ajustes. Viene con un adhesivo para enganchar a la pared o desde el propio dispositivo se puede mover una placa que tiene atrás para apoyarlo en si mismo, algo muy util.- Buena fiabilidad en la detección: he experimentado que cuando entro en la estancia la luz se activa al instante, y cuando salgo/no hay movimiento se apaga tras unos segundos, lo cual ayuda a ahorrar energía.- El tamaño me ha sorprendido para bien, es muy pequeño y ligero. También viene con una tapita para ocultar una parte del sensor para que no se active si hay mascotas por casa, algo realmente util, que pensaba al principio que no funcionaria, pero va mejor de lo que me esperaba.Contras:- Requiere conexión eléctrica permanente (no depende de baterías). Si lo instalas en una zona sin fácil acceso a una toma o cableado, puede implicar más trabajo.- En espacios muy amplios o con obstáculos puede que la detección tenga pequeños fallos: por ejemplo, si la habitación tiene muchos muebles altos o está muy compartimentada, el sensor tarda un poco más en captar la presencia.- Si bien la integración con Alexa ha sido fluida en mi uso, si tienes un ecosistema muy diferente (por ejemplo HomeKit, o otro sistema de automatización poco habitual) puede requerir algo más de configuración.- Sería deseable un manual más detallado en castellano (aunque la app hace gran parte del trabajo).En definitiva, el sensor Meross MS600 me ha generado una excelente impresión: cumple con lo prometido, facilita la automatización de la iluminación de una manera práctica y fiable y se integra muy bien con mi sistema doméstico inteligente basado en Alexa. Por tanto, lo recomiendo sin dudar para cualquiera que quiera dar un paso hacia una casa más “smart” con mínimo esfuerzo.

Il déclenche sans arrêt sans raisonNe détecte pas quand il y a du passage, n’est vraiment pas fiable.Il est hors prix également pour la qualité de la finition en plastique semi rigide.Satisfait des produits MEROSS mais celui-ci est en dessous de tout
Mauricio –
El sensor es excelente en efecto detecta tanto la presencia como el movimiento y el número de lux, por lo que se pueden crear muchas automatizaciones, le doy 4 ⭐️ estrellas porqué a pesar de que la función de Meross muy completa la integración de matter con Apple Home tiene la configuración de los s sensores limitadas.

Équipé de domotique à la maison, il n’a pas besoin d’un hub domotique de la marque, de plus il est compatible “Matter”.Le capteur de présence & capteur de lumière Meross MS600 s’intègre parfaitement au sein de mes applications HomeKit & Home Assistant.L’installation physique est très simple, le manuel Meross (à télécharger sur le site Web Meross pour la version en langue française) et suffisament explicite pour positionner le capteur à l’endroit souhaité.Il faut avoir une prise électrique à proximité car il se branche au secteur grace à son adaptateur 5v USB fourni, le cable de 2m est peut être un peu court!Grace à son “pied/dos” astucueux, il peut être posé sur un meuble ou fixé sur un mur dans la position souhaitée, le cable USB trouvant sa place quelque soit la position.Il est doté de plusieurs technologies pour la détection de présence et la mesure de la luminosité.Sous les applications domotiques:- HomeKit il apparait comme 2 capteurs (présence et luminosité)- Home Assistant c’est 18 entités qui peuvent être intègrèes.Dès lors on peut facilement créer des automatisations sous l’une ou l’autre de ces applications. Exemple ci-dessous:Si présence détectée entre 09h00 et 18h00 et luminosité < 150lux alors allume "Lampe Salon"Il est fiable, il n’y a pas de faux positifs, il détecte presque instantanéement quelque soit le contexte, vitesse de déplacement ou changement de luminosité.il est cependant préférable de l'installer légérement en hauteur pour une détection sans faille lorsque qu'il n'y a pas ou peu de mouvements.Points d'attention:- l'insertion dans l'application HomeKit est sensible. Il faut absoluement que le Hub Apple (HomePod, AppleTV) et le MS600 soit sur le même réseau IP.- le smartphone qui insère le MS6OO doit être sur le réseau Wifi en 2,4Ghz sinon cela ne marchera pas.- Il est préféable d'associer en premier le MS600 à l'application Meross installée sur le smartphone avant d'insérer sous HomeKit et/ou Home Assistant.- Il est sensible au positionnement en hauteur. Le niveau "épaules" (1,50m) pour ma part me semble le plus adapté.Il est plutôt abordable, le rapport qualité-prix est excellent.
