If you’ve been waiting for a smarter, simpler way to make your home feel truly automated, Meross just dropped something that might catch your eye. The company’s new MS605 wireless presence sensor promises up to three years of battery life — all powered by the energy‑efficient Matter-over-Thread standard.
The standout change? No more wires. The MS605 runs solely on a single CR123A battery, freeing you from the hassle of drills, dangling cords, or awkward placement. You can mount it just about anywhere — on a wall, ceiling, or near a doorway — and it’ll quietly do its job.
Despite cutting the cord, Meross didn’t cut corners. The sensor combines PIR motion detection with a 24GHz mmWave radar, a pairing that lets it recognize both movement and subtle still presence. In other words, it can tell the difference between a person relaxing on the couch and a curtain swaying in the breeze — or even ignore your roaming robot vacuum.
And it’s tougher than before, too. With IP67 weather resistance, it’s built to handle dusty corners, outdoor spaces, or steamy bathrooms without complaint.
Of course, going wireless does mean a bit of a range trade‑off. Motion detection now tops out at six meters (half of what the wired version offered), and presence detection reaches about four meters. Still, for most rooms or small apartments, that’s plenty of coverage.
The best part? It won’t break the bank. With a price tag around €35 (about $38), the MS605 sits comfortably in the affordable smart‑home range — and it plays nicely with just about everyone: Apple Home, Google Home, Amazon Alexa, and other Matter‑compatible systems.
For years, the smart home world has felt like a collection of islands — each with its own ecosystem and quirks. Matter and Thread are slowly changing that, creating a common language so your gadgets can finally talk to one another without frustration.
The MS605 feels like a glimpse of that future: a small, battery‑powered sensor that’s easy to install, universally compatible, and incredibly efficient. Picture your lights dimming when you leave the sofa, or your heating switching off once a room empties — no apps, no accounts, just seamless automation that works quietly in the background.
The MS605 might not look revolutionary at first glance, but for anyone chasing a smarter, cleaner setup that just works, it could be one of those small gadgets that make a big difference.
