2.0 out of 5 stars This would be great if it worked with Alexa (like it says it does)

2026-01-16    -R. Carlson

I was looking for a sensor to turn some lights on and off using an Alexa Routine. This is really a great design -- it's got a built in battery but it looks like you can just leave it on a charger , but note that you need to supply your own USB power source. There's no instructions on how to prepare the unit, so here's a hint: It unscrews. Simply twist the two parts and they will come apart. You then need to pull the shipping tabs from around the battery. You'll also find the hidden RESET button in side.I got the unit connected to SMARTLIFE app easily enough, and it immediately started to send notifications to my phone. Good so far. It has a "tamper" alarm that goes off if it's moved as well as temperature and humidity. I turned those all off since I don't need them. I wanted to turn on the lights in my bathroom when I walk in, and for my purposes the range seemed good, with no falsing. If you wanted to use this as a motion alarm or to control other Smartlife devices this would probably work fine.The first problem comes when trying to connect to Alexa. I did DISCOVERY and Alexa found it, but then showed "there's a problem" as the status. I was able to add it to an Alexa routine, but it was unable to send any motion events to Alexa, so the routine never triggered.The second problem came when I tried to get support. The listing states "If you have any questions about the home security sensor alarm system, please feel free to contact us, we will reply you within 24 hours and do our best to achieve 100% in customer satisfaction." The problem is there's no indication of how to do this. There's no place to get technical support in the documentation for the product. I left a message for the seller. I contacted AMAZON support, who basically said to try everything again (I did, it still didn't trigger Alexa).Obviously, neither of these make it a very effective purchase so it's being returned.Pros:- the step up went smoothly with SMARTLIFE- Does not require a hub- Two VERY large batteries for a long lifetime- You can keep it plugged in- Tamper, Temperature and Humidity alarmsCons:- Alexa integration does not work- A USB Power source is not included- A little priceyRecommendation: I would not recommend this if you are looking for Alexa integration, if you just want to operate it through Smart Life, you should give it a try.Notes to Manufacturer to make this a better product:1. Include instructions on how to open the unit and pull the battery tabs and show a picture of the reset button2. Provide a URL or email for customer support in the documentation3. Either fix the Alexa integration or remove it from the listing4. Note that a USB power source is not included in the listing

3.0 out of 5 stars OK for motion sensing. Temperature is not accurate when powered by the USB

2026-01-07    -MJB

We purchased this as a motion trigger for light control and it works OK. However, there are a couple of shortcomings. First, the temperature consistently runs 6 to 10 degrees above real room temperature (via calibrated measurement). We can only guess that the constant USB power heats up the device so that it is warmer than the surroundings. But, we don't use the temperature for any control purposes. Secondly, the sensor does NOT have a user selectable time-out period. It must see NO motion for 30 seconds (approx) before it will trigger another detection. So, if something is moving every 15 or 20 seconds, the detector doesn't reset. Other sensors allow the user to select the time-out period (we have a zigbee sensor in the same room, user selectable from 1-60 seconds). It would be a nice feature. So, we give it a 3 out of 5 rating.

Easy connectivity and perfect area you want notification for motion. Works great with Alexa.

No funciona tan bien.

5.0 out of 5 stars Best motion detector October 2022

2025-12-25    -Pete In Illinois

When I first saw this motion detector, I was hesitant. In the past, I used one that would drain batteries every three weeks. Despite trying their latest model, I had to return it. I am very pleased with the performance of this motion detector. By connecting this to a USB wall plug, you will no longer have to eat batteries. It takes only a few seconds for the sensitivity to work. In my kitchen, I have it set so that the lights turn on when I enter. The lights in the kitchen are turned off after 30 minutes if there is no movement in the kitchen.

5.0 out of 5 stars works great and the battery it has is a plus

works great and the battery it has is a plus. if the power goes out it still works. you have to have it's wifi connection still powered though. my wifi router has a backup power supply but if its tethered to a hot spot or your cell phone it will work.
