Eve Motion (Matter) 3-Pack – Smart Motion and Light Sensor, IPX3, Automatic Activation of Devices, Future-Proof, Works with Apple Home, Alexa, Google Home, SmartThings, requires Thread Border Router

Great little product. Works perfectly with my garage lights. Matter via Thread makes setup via Homekit or Home Assistant a breeze. Also within the dedicated Eve app, you can customize the sensor's settings to tailor it for your specific needs. Highly recommend once you understand how it works.

The good: It works, sort of. I set it up, and it does detect motion. I used it with Homekit and it connects with it after a couple of tries. I wanted to use it to turn the lights on when I enter a room and off when I leave.The bad: It doesn't continually detect whether you're in the room, so it's not good for what I wanted. it turns the lights on, but it was too difficult for me at least to get it to keep them on until I leave. The best I could do is have it turn on, wait 10 minutes, then turn them off, if it didn't detect me. but it does not detect me if I'm sitting still. So it turns the lights off and then when I move again, it turns them back on, which is annoying. The solution to this is to get a presence sensor, not a motion detector and Aqara sells a presence detector, which I hope will work a lot better.Also bad: I changed the name of the Wi-Fi in our home and had to reprogram this to use the new Wi-Fi and it failed totally. I couldn't get it to work anymore so even though it had good reviews, I definitely would not buy it again.Edit: after several tries, and resets, I got it to pair again, but it failed almost immediately. So even if you're willing to accept it being just a motion detector, Be prepared for it to only work for a few months.

This is a great motion sensor I'm using in combination with the Eve Smart Switch to automatically turn on the lights in each of our bathrooms around the house. Set up an automation in Apple HomeKit and bam - you're set! The only issue is the mounting isn't as easy as most sensors I've used in the past. The battery lid is on the back of the device. The back of the device also has a screw hole for mounting to the wall which is nice, but it means that you'll have to use this as the only way to mount it to the wall. The other issue I have is the QR code to add the device to your smart home system is printed on the bottom of the device so everyone can see it when this is mounted to the wall using the mounting hole. Odd. Overall, if they changed those two design flaws, this would be a perfect motion sensor. Other than that, it works very well and is easy to connect to your smart home. However, you'll need to ensure you have the Thread protocol on your network or it won't connect at all. I literally had to upgrade my Apple TV to the latest version in order to use Thread. Yes, I could have purchase a Thread hub, but why spend the money when I get a two-fer by upgrading my Apple TV, right? Right. Anyway, this is a decent motion sensor that works well.

This motion detector works great and simple to set up with Google Home. We had someone go up onto our porch and steal a cheap wooden bench in the middle of the night so bought this to create a routine that if motion is detected on the porch it will turn on the lights in two different rooms, turn up the volume on one of our home speakers and trigger a 30 second doorbell and barking dog audio file to trigger our dogs to start barking. Then when motion is no longer detected it will turn off the lights. This was super simple to do in the google home app by following the setup to connect it to Google Home.The one thing I believe most people miss is that when setting up you have to ensure the network you are on is 2.4ghz. I did make the initial mistake of forgetting this and the unit would not work. Realizing this, I simply removed it from google home, connected to our 2.4ghz bandwidth and then reset up and once that was done everything was simple to set up and then create a routine for it as mentioned above. One thing that would help users is if they could show what wifi network the unit is connected to in Google Home. I cannot speak to the SmartThings app as I did not want another app install.The detection is pretty good, range was a bit too long for us to point it toward the street as it would trigger when cars passed by about 30-35 feet away, so had to point it toward the house. The cone of detection seems to be about 160-170ish degrees so works for our purpose and we don't get false alarms now from cars or people walking on the street.Overall, this works quite well as intended was super easy to set up. Once realized the 2.4ghz was required, it too a total of about 15-20 mins to connect to Google Home and have routines set up. It does require a hub to connect to, so keep that in mind also if you do not have a Google, SmartThings or other compatible hub already.

My application seems quite different from what most people are doing with this sensor. First of all, I needed an ambient light sensor to control lights and shades, and this was the only one I could find that would work for me. I don't need motion sensing - there are plenty of these, but very few light sensors. Luckily for me, this does both; I just don't use the motion sensing.Next, my control system is based on Apple HomeKit, not Amazon Alexa or Google. I require devices that don't depend on constant Internet access to work, and this is one of the few for which that's true. My entire home automation system can operate when the Internet is down (but power is on, of course). This is critical when you're controlling heat (burst pipes, anyone?), lights (make it look like someone's home), and other functions. Plus, although I can monitor from outside or be alerted when the Internet is up, my devices don't "phone home" and minimize my system's vulnerability to attack. These are, in my opinion, severe shortcomings of nearly all other home automation ecosystems. By the way, no one is collecting data on me to add to some AI engine or to sell. My privacy is worth something!This product isn't perfect, but it's doing what I need it to do. The AAA alkaline batteries have lasted over 1.5 years, and that's acceptable. I might try replacing them with lithium batteries when the time comes.
