## Description

desertcart.com: 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 : Electronics

Review: Great Presence Sensor - 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?
Review: Seamless integration, as a trigger, for TreatLife smart switches - 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.

## Features

- WiFi Connected, No Hub Required: The mmWave presence sensor operates seamlessly without a gateway, relying solely on a 2.4GHz Wi-Fi connection. Compatible with Alexa and Google Assistant, but doesn't support SmartThings and IFTTT. With a wired design ensuring stable power, it operates on 5V 1A USB power, eliminating the hassle of frequent battery changes. The communication range reaches about 263ft without obstacles
- Ultra-High Precision Detection with More Privacy: Utilizing millimeter-wave radar technology, our human presence sensor accurately detects various movements, micro-movements, and stationary states. This ensures that lights won't unexpectedly go out during stationary activities like reading or toileting, without the need for a camera monitoring system, preserving user privacy
- Advanced Sensing and Instant Alert: The 24GHz mmWave Radar smart sensor excels at detecting subtle movements, offering higher accuracy than PIR (not a presence sensor). It promptly sends alerts to your smartphone upon detecting unusual motion, enabling you to conveniently review 30-day activity logs through the app, regardless of your location
- Customized Whole Home Automation: Utilize this motion sensor indoor as a motion-activated wall switch to automate various routine tasks by configuring "IF" conditions and corresponding "THEN" actions. For example, Reading Mode adjusts brightness, Child Monitoring Mode activates surveillance for safety, Energy Saving Mode minimizes consumption during the day. The seamless collaboration of these modes delivers users a precise and personalized smart home experience
- Flexible Installation and Extensive Detection Range: The wifi presence sensor features a magnetic base that allows for 45° folding and 360° rotating, allowing you to mount it on the wall or ceiling with a maximum detection range of 20ft. Avoid installing it near swinging plants, moving metals, or fluttering curtains to prevent false detections. Note that the human sensor is not waterproof or moisture-proof, so ensure it’s installed in a dry area for long-term durability

### ⭐ Too sensitive or not sensitive enough. Take your pick but there is no Goldilocks setting.
*by P***N on January 31, 2025*

I wanted to use this device to turn lights on and off in a home office. I was unable to get it to work the way I wanted - either it was too sensitive and would turn on when nobody was even in the office, or it was not sensitive enough, and would turn off when working at my desk or reading. It doesn't help that that the app is a little inscrutable. You have settings between 1 and 5 for movement and another setting of 1 to 5 for micro movement. How are these things even different? No explanation for what they are. There is also a setting for the distance, in cm, that doesn't really work. I tinkered with these settings for weeks, and never got them to work properly. The lights would come on when I walked past a wall outside the office. Finally, last night, it was continually turning on and off while watching TV in an adjacent room - the two humans were will outside the 3.75m meter range, but the device went ahead doing its thing. That is where I gave up. This might work better in a really isolated area, but for me, it's not usable.
