A cord-free upgrade for smarter spaces
Meross expands its smart home lineup with a new version of the MS600 presence sensor, now redesigned to run on a battery. The MS605 removes the need to hide or manage a power cord, opening up placement options across hallways, bedrooms, and living spaces where traditional wired sensors were inconvenient. This shift improves versatility for renters and homeowners alike who want intelligent occupancy sensing without the burden of wiring.
Power and longevity you can trust
The MS605 uses a single CR123A battery, delivering up to three years of operation under typical usage. That longevity reduces maintenance and battery-change frequency, keeping your smart home functioning without frequent interruptions. When the battery eventually nears the end of life, Meross typically provides guidance on replacement timing to minimize downtime.
Thread support brings reliable connectivity
One of the standout features of the MS605 is Thread compatibility, a modern, low-power mesh networking protocol designed for smart home devices. Thread enables robust, self-healing connections between the MS605 and other Thread-enabled hubs and sensors, helping to maintain consistent presence data even in busy Wi-Fi environments. For households already deploying Thread networks, the MS605 fits in seamlessly, reducing latency and improving overall reliability of presence-triggered automations.
What the MS605 brings to your smart home
Designed with practical placement in mind, the MS605 can be installed in locations where battery-powered sensors excel—areas where cords would be awkward or unsightly. With occupancy sensing, the device can trigger lighting, climate, or scene changes when people enter or leave a room, contributing to energy savings and enhanced comfort. The form factor emphasizes discreet installation, so you can place the sensor high on a wall, near a doorway, or in a hallway without worrying about visible wiring.
Simple setup with existing ecosystems
Meross has focused on ease of use. The MS605 pairs with compatible smart home hubs and apps, allowing you to configure automations like “turn on lights when presence is detected after sunset” or “adjust thermostat once occupancy changes.” Thread support also means fewer network hiccups, particularly in homes with many smart devices competing for bandwidth. For users new to Thread, the MS605 may work with a compatible hub that bridges Thread to their preferred ecosystem.
Practical tips for optimal placement
To maximize effectiveness, place the MS605 at typical human paths and avoid corners or areas with frequent pet movement that could trigger false positives. Pair the sensor with a routine that confirms presence with a secondary trigger (like a door sensor) if your home setup requires higher precision. Remember that battery monitoring is essential—keep an eye on the status through your hub’s battery indicators so you don’t experience unexpected downtime.
Conclusion: flexible, long-lasting occupancy sensing
The Meross MS605 marks a sensible evolution for presence sensors by combining battery power with Thread support. It offers installation flexibility, durable battery life, and reliable connection in modern smart homes. If you’re looking to reduce cable clutter while keeping your occupancy-driven automations intact, the MS605 is a compelling option worth considering.
