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

This one really works great. I automated this to open my room treatlife light switch.

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.

This smart sensor works good. Unfortunately, it is not compatible with Home Assistant.That said the controls are extremely responsive. It seems to be excellent at saving its battery, meaning it’s not exactly on all the time, running the battery down.The app for controlling it on your phone is actually good. It has a very good layout and user interface.I read somewhere online that the firmware could be reflashed on a sensor of this brand so that I could use the sensor with Home Assistant. Unfortunately, it turned out that I don’t have the soldering skills to actually make that happen. Live and learn.This door sensor is a good value for its price. But because it does not work with Home Assistant, I would not order one again.

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 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.

Magnet it too small. Falls off door / doesn't stick well. Was easy to set up on phone, and i did appreciate that it was not a bulky device. Not best choice for doors with framing. Would recommend for back sliding door or maybe window.

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

This is a good sensor for connecting directly to wifi, with no hub required. Yes, there are more robust systems available, but this one fits me well as it's simple and doesn't require any additional hardware. I needed something to let me know when the garage was open or closed, and this has worked out perfectly.The device was easy to set up. I like that it uses Smart Life (aka Tuya) - I already had the app up and running with other devices. (Hint: open the battery case and hold down the button for 5 seconds before initiating the scan). The app quickly found the sensor, as did Alexa. The wifi range on the device seems good - it's never dropped out and there's about 100 feet and 3 wall between the wifi access point and the sensor. Also, I like that this device works over a relatively large distance - it will pick up on the magnet when it's about 1/2 an inch away (11mm). For me, this is great, because the garage door has a rather large gap. Push notifications from the app are quick - most arrive within 5 seconds. Alexa integration works flawlessly. It's really handy to ask Alexa, "is the [contact sensor] closed]?" Also, I now have that as part of a routine at the end of the day. Alexa turns off all the lights and tells me if the garage is closed.
