TREATLIFE WiFi Presence Sensor 1 Pack, 24G mmWave Radar Smart Motion Sensor Wired, Support Alexa/Google Home, Real-time Human Occupancy Sensor, No Hub Required

Some notes from my experience: 1. Very easy setup. 2. No connection issues, unlike every Matter sensor I have tried. From my experience, Matter devices routinely go offline and can be difficult to get back online again. 3. Very responsive, and you get some settings to customize, though I have had no need for that. When used to control room lights, the lights come on almost the moment you enter the room. With the Matter sensors I've tried, you can be to the middle of the room before the lights come on. 4. This is a true presence sensor. 5. You do not need the Treatlife app. This device is powered by Tuya and works just fine with the SmartLife app. The Treatlife app offers no functionality that SmartLife does not. 6. Has been working flawlessly for me. And the price is lower than the Matter sensors. What's not to like?

I don’t understand why so many negative reviews when this sensor works like a charm. I have 5 of these around my house. Very accurate even behind obstacles like toilet seat or a shower glass. Doesn’t take much to fine tune. Rarely misses.

It was very easy to set up and create routines. That’s all the good I can say about it It is detecting “presence” in a completely empty room constantly. I have adjusted the sensitivity and ranged to as small and as low as they can go, and no matter what my delays are, no matter what I have the settings at, it detects someone all the time, and keeps the lights turned on constantly. Very frustrating because it looked so promising. I will keep messing with it and if it decides to work for me, I will update my review otherwise it’s likely heading towards a return.

Actually, it's not bad at all, even though it's doesn't work properly, however, it's works perfectly in most of time, so i guess i will buy the second one soon

Excellent. Ignore all bad reviews.

The TREATLIFE WiFi Presence Sensor promises smart motion detection with its 24G mmWave radar, but it falls short if you’re thinking about serious home automation. Out of the box, it works fine — it detects presence reliably and can trigger actions within the TREATLIFE ecosystem. But if you want to integrate it with Home Assistant or mix it with other smart devices, you’re out of luck. The sensor is locked to the TREATLIFE app, and it requires other TREATLIFE devices for full functionality. It’s decent for casual users who don’t mind staying inside one app, but for anyone building a custom smart home setup, this sensor quickly becomes frustrating.

Mounting was seamless, be aware you need a USB-A brick or an outlet with USB-A female port. Setup was simple, TreatLife has come a LONG way from the first smart switch I purchased years ago. By the time you hit “+” in the SmartLife app, the device has already been discovered and the app retains the WiFi login credentials from your previously set up devices. We’re using the TreatLife motion sensor in the garage, when motion is sensed, it triggers the two garage light switches and turns them on. This allows full-light when arriving home at with the car or bicycles etc, and doesn’t leave us dependent on the anemic, pathetic, single LED light built into the garage door opener. You can park or walk in with ease and not have to get out, turn on the lights, get back in the car, finish your park and then turn off the lights before you leave. The lights are currently set to 15 minutes, and with no motion, turn off. Learning the various motion sensitivity settings will only make a perfect motion sensor, beyond perfect.

Absolutely love them, the features are way more complex than I thought. You can set up the device, so if you get within a certain distance ( I have one in front of my oven, and if I'm within 4 ft of the oven, our oven lights turn on). Absolutely love it, and if you use Smart Life you can program it to activate when there is light in the room, movement in the room, somebody gets within a certain distance, it's pretty incredible
