TREATLIFE WiFi Smart Door Sensor 1 Pack, 2.4GHz Window Alarm Sensor, Wireless Contact Sensor for Home Security, Smart Home Devices Compatible with Alexa and Google Assistant

I was looking for a product that would integrate with alexa with additional subscriptions. You will need to download the trulife app and manually add it to alexa as it's a 3rd party application. I only use this to notify me if/when the door opens. I am able to see through alexa or the trulife app if the door is closed. Peace of mind.

I like having a smart home. When available, I try to add as many devices as possible around my house - both for the functionality (ie. notifications, alerts, 'triggering') as well as the safety. I really value having one devices talking to another (or really, reacting & taking action based on another).Admittedly, most of my devices use a Z-wave radio/network. Some of my devices use a Zigbee radio/network. As both of those networks are mesh, there was value to 'the more the merrirer' to build as strong of a network as possible (although, still frustrating that I have to be continually be 'starting over' with new networks). Having this door sensor as a wi-fi device addresses the 'needing to build a network' issue, but at the same time - being all of the different devices & gadgets that we have nowadays, I'm increasingly worried about network congestion. I have my IoT (Internet of Things) devices on a seperate SSID, but I am worried that at some point - 'streaming a movie' is going to interfere with 'security & safety' or vice versa.All of that said, I was happy with the sensor itself. It was easy to install, well-sized, and adding it to my smart home network was easy enough. I use a SmartThings hub to control everything, but I added this to my Treatlife app & then imported it into SmartThings. A direct integration would have been better, but... whatever. I only need to go through that process once & there isn't really any functionality that I feel that I'm missing through the SmartThings import.I'm happy with this sensor & happy to recommend it to others.

I like this, it does the job and works well. It's easy to use and to place. Easy to set up and works better than I expected especially for the price. The sensor is strong and the overall product works really well.

There was a bit of a delay in receiving a response. Have your own double sided tape. The tape included didn't last.

I have only good things to say about this TreatLife Wi-Fi Door Sensor, it was something I had been looking for a good while. Most smart home/security system add-ons usually connect through a proprietary hub or through Bluetooth direct to a phone app. This sensor actually can connect through 2.4ghz Wi-Fi directly. This was great, as I was able to track an actual IP/MAC and know exactly what my connection is and what it is doing at all times.The kit comes with everything you need to add it in to any existing smart home and security setup. You can view and work it through multiple apps, including Tuya, SmartLife, Home Assistant, etc. It also works good with Alexa and Google voice command once you get the apps integrated and enable the Skills correctly. I used this to hook to a rear door that get's a lot of use and wanted something that was more reliable then just a plain Z-commo style door magnet sensor.Installation was super easy, just like any other door or window sensor. It actually even came with batteries to get you started, but I recommend using lithium batteries in all smart home and security devices. I was up and running within minutes and was able to customize it a great deal. You can really do a lot with it if you know a bit about smart home communications or even just using IFTTT or similar connectors. Made well, sturdy materials, great functionality, easy to setup, 5 Stars.

The WiFi Smart Indoor Entry Sensor is an excellent addition to my home security system. It’s easy to install and set up, working right out of the box and adhering well to my trim. The sensor functions effectively with gaps of up to 0.39 inches (1 cm), which is great for surfaces that aren’t perfectly flush. Its compact size means it doesn’t take up much space and is barely noticeable. The price is reasonable, and the Wi-Fi connectivity is reliable, making setup a breeze. I receive real-time notifications on my smartphone whenever a door or window opens or closes. I appreciate the discreet design and battery efficiency, though a longer range would be beneficial for larger homes.

This product was affordable and does the intended job of alert and safety. I definitely felt safer after installing it and realizing how much the product truly was needed. I love how loud the sound is. I can actually hear it from any room in my house which is helpful since my home has no doorbell. I would highly recommend the purchase.

The only reason I gave this sensor set four stars was because the small magnet that sticks to the area just above (or to the side of) the door to trigger the sensor, fell off within the first day. There's really not much surface area for the adhesion to grab onto. So I'm going to have to probably use some crazy glue or something stronger.As far as the sensor, it stuck on the door and stayed on the door with no problem. Everything connected beautifully to the app and worked great. In fact, I was getting notifications right away on my phone when the door was being opened or closed. So basically everything works beautifully, just needs better adhesion on that small magnet piece.
