    Very good sensor. It informs the current port/window status, informing whether it is open or closed in real time. It is possible to do automation with it by both Ewelink’s APP and Alexa. Soon I will review my YouTube channel, who wants to look for Consumer Tech there!


  2. ABR***HM

    It’s a genius thing. All you need to know about the pairing is that if you can’t connect it to the WiFi first round, then you can start using Bluetooth and then go straight to the WiFi. The notifications also work great, I am completely satisfied with it. It arrived in 4 days and was delivered by a courier service. I’ll take my hat off

  6. mdayyubkhan27

    What to say about this little product, I simply love it just have a little imagination it serves several things at the same time, trigger scenes, alarms, switched on or off other devices and so on and it can be installed in different ways


  7. mdayyubkhan27

    deliver in 5 days. I bought them to automate some lighting in my house.


  8. mdayyubkhan27

    They’re having a little four-second delay. They’re doing their job anyway. Plastic quality is good. 3M stickers, and they take two AAA 1.5 batteries. Very easy connectivity to the ewlink program.


  9. mdayyubkhan27

    Very good product, later I’ll get more. Paring is done via Bluetooth, then it leads you alone.
