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

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.

So far so good. I have this set up to turn on my main office light (Kasa light switch) and an overhead light (via Kasa plug). The plug lags about a second or 2 behind but main light is already on. Distance pick up is perfect as it is right at the entrance to the room and the sensor is on the other side. This allows for it to do a good job on knowing I am at my desk working. Turns off light after a set time that I have in the routine (running in Google but looking to get moved over to H.A. at some point).

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.

I've had some issues with it... quite a few. But recently I've got it in a good spot working off a reliable plug, and it seems to be okay right now. It's not perfect all of the time but right now I'm more pleased than not. It's very sensitive compared to my zigbee battery motion sensor. You can adjust the sensitivity, micro sensitivity and range.

Glad Treatlife is adding presence sensors. Others in my household are always leaving the kitchen light on. As it's already on a treatlife switch, I just added this sensor, and with the Treatlife app was able to add two routines, one to turn the lights off when presence is no longer detected, and one to turn it one when presence is detected. I'm happy that it turns on very quickly, even before I'm able to reach the switch when entering the room. The only slight downside is that the app is configured to give a phone notification every time the sensor is triggered. This got annoying REAL quick, so I had to disable all notifications. I didn't see how to turn off just the ones from the sensor. BTW, it turns off after about 30 seconds of inactivity by default. There are a bunch of setting to adjust in the app, including distance and times, but I didn't have to change anything.

When it works, it's great, however, I have it set up to trigger Philips Hue light in a bathroom and at least once a day, there is a significant delay in the trigger, sometimes even as long as 45 seconds. I have the routine set up with Alexa AND Google Home as a backup in case one or the other was causing the delay. Nope, it's something with the product and I have no idea why.I have 50 smart home devices spread throughout my 2 story home with 2x Amplifi Alien routers and 1GB internet. No other devices from multiple different brands cause me issues. Because of this, I will be returning to using the Philips Hue motion sensor I was using flawlessly for years. While I don't expect a wifi sensor to compete with the reliability and speed of Zigbee devices; a hiccup everyone once in a while is acceptable, not once or more times a day.

Treatlife updated their app and apparently their firmware. As in the past the way to add a Treatlife device to home-assistant required adding it to Smartilfe/Tuya. I was able to add it to Smartlife but it failed to detect presense. It worked fine with the new Treatlife app but there's no pathway from that app into home-assistant. There's not anything in HACS either. For me that makes this presense sensor unusable. It might be usable if I used the paid Treatlife subscription service but I'm not willing to try that

These are sensors that you can place anywhere and program them to do whatever you want within the app (trigger scenes, turn on lights, play notifications, etc). It integrates with Amazon/Alexa (which is how we use it). This is great because we have one set up in the Kitchen and have it trigger the lights to turn on during certain times in the middle of the night. It helps when we are walking into the Kitchen and the lights turn on automatically. The uses are really up to your imagination. You can also trigger them to set up an alarm on your phone if they sense movement. A great idea would be to put them in a liquor cabinet and protection from kids. Very cool devices - I love them.ALSO - you can stick them on walls/ceilings and you can angle them. Very versatile.
