Smart Window Door Magnet Sensor Detector Compatible with Alexa Google Home Controlled by Phone iPhone Tablet for Home Burglar Security Alarm System (2 Pack)

I have these on outer doors to announce through Alexa if either of the doors are opened/closed , also switches on the lights if either door is opened after Dusk for a limited time. Easy to configure. Adhesion is excellent, the only complaint is they can be a little slow to respond so the door open event may take 4 or 5 seconds to respond. This could also be down to the Alexa routines app of course. Great Product for the price though will be buying more.

When they work they work well. Easy to setup with the app. Mounting on doors is ok to a point. However it is tricky sometimes to get the sensor to acknowledge a door is closed. I have sat in my office and looked at my door at home and it indicates it is open. When i get home I find it closed and the sensor and magnet are aligned. Sometimes opening an closing the door fixes it. If you are ocd this will put you in therapy. I have 4 and they all do the same thing.

This was easy to setup, the adhesion was good but the reliability wasn't great. Not sure if this was down to the sensors or the smart life app, but other products I have use the same app and work great so I'm inclined to think it was the sensors.Additionally, there was no way I could see to setup a schedule of when they would send you a notification, it was either on or off, which wasn't much use when they were on a main door. Even tried convoluted configurations between scenes and automation to get around this, but little success. As such, even if these had worked perfectly, they still wouldn't have been much use unless you don't mind them constantly pinging off alerts when your in the house. Shame.Might be suitable for something where reliability isn't essential to normal operation, e.g switching lights on when you get home and open a door.

Overall good product but it has really slow response rate. I configure it to send notifications to iOS and Alexa, but in average it takes 6-8 seconds to get those. Often my second notification that doors are closed overrides first one. Also when I'm outside of my private network notifications sometimes don't arrive or arrive really late (20mins or so).Other than that I does good job, easy to configure, tells you when doors/windows are opened and when closed etc.

Bought these to automate turning on and off of lights based on door or garage opening. I have used Tuya with other smart products so had no hesitation purchasing these. Installation and set up was easy. Only issue I found was that one of the two switches was a little unreliable. Customer service was great at finding me a resolution to the issue. Will definitely be buying again.

Don't work for very long

Work okay as long as the gap is very narrow. In practice this needs to be somewhat less than 1cm and you need to temporarily fix and test well because once they’re on, they’re on!

The product is great, has its own app and you can link it with Amazon Alexa which can turn on the alarm sound etc. Seller is great, Could not have done enough to help with a problem I had. I would buy again knowing the seller would help in every way he could. Could not have asked for more from this seller. Would highly recommend..*****
