    I did not communicate with the store. Delivery is fast, three weeks to Komsomolsk-on-Amur. The Tuya smart app directs the configuration action. The sensor works, messages come instantly, it’s at home. The sensor is not bad, you can buy.

    Responds well to water contact and is very reliable. The Tuya app is the best on the market.

    I checked while one sensor, it works. But the mount is terrible. The sensor is fully attached for the sticker. If the battery sits then the sticker is thrown out. For another to remove the battery is problematic. The previous time I ordered a sensor there, the sticker was fastened on a plastic cover, which can also be screwed with somoresis. And the sensor was inserted from the side, which was very convenient.

    I’ll buy it again.

  19. 5 out of 5


    Everything perfect except the shipping time that was super slow, two months. Otherwise perfect unless it doesn’t connect well with Alexa, it doesn’t let it set well

    Coupled to the app, the sensor works perfectly!

  32. 5 out of 5


    It works perfectly, its configuration has been easy and fast through the Smart Life app. It supports Alexa and you can create routines. The shipment took a few days longer than the estimated date.

  33. 5 out of 5


    The sensor works very well, it is easy to install with smart life, it goes super well integrated. It’s been in use for almost a month and fits the doors and windows quite well. The app is very well integrated with this device. The shipment was faster than expected. The store very well. Quality unbeatable price. I recommend it

  34. 5 out of 5

  35. 5 out of 5


    warning!!! I’m very happy with the product. and gave 5 start, BUT: i made a mistake and put battery upside down, and the product got so hot and plastic start melt, it’s my mistake but please be carful, this device can make your home on fire if you make this mistake. i don’t understand how they got CE or FCC.

  36. 5 out of 5


    good for me.

  37. 2 out of 5


    Bullshit full! A couple of days worked perfectly, then stopped responding first only to opening, and then already on closing too… Or send a notification only about closing the door minutes after 5, and on this of course thank you. Had me before this sensor from other manufacturer/store, he worked until the first pair of batteries did not sit down, with a second pair of batteries already did not start… So it’s bullshit, you better get a dog…

  59. 1 out of 5


    By mistake buy from this store, I don’t recommend it, you lose your money, time and product never comes, asks them and stumbles q ask in mail and nothing else. Mail tells you q isn’t there and AliExpress gives them the reason and not just passed me Ali I have some friend and neighbor with bad experience in this store.

  61. 5 out of 5


    great product, I’ve got 5 already

  62. 5 out of 5


    got 5 already, on the doors, the Windows, sliding doors.

  63. 5 out of 5


    Before St. Petersburg for 2 weeks. Look good. Installation is simple. The delay when triggered is minimal. Put on the front door, in pairing with the WiFi switch, turn on and turn off the light in the hallway. You can configure different work scenarios. Recommend.

  64. 3 out of 5


    To be honest these were the rubbish, all kept giving false alarms “door open, door closed”, I had previously bought others from a different supply with no problems. The three of them have been disposed of. No recommended.

  65. 5 out of 5


    très bien

  66. 4 out of 5


    The battery runs out very soon. I don’t think I’ll make it to the month and I don’t open the door constantly, at least once a day. For the rest of you.

  67. 5 out of 5


    great product. fast delivery

  68. 5 out of 5


    It works very well. It takes about 2 seconds to send the notice

  69. 5 out of 5


    bon vendeur, bon rapport qualité prix, description correcte, mise en place facile, il faut attendre un peu que Smartlife puisse le détecter, ca fonctionne parfaitement, alertes d’ouvertures de porte, mémoire et historique des ouverture et fermeture, scénario possible pour allumer ou éteindre des lumières ou faire.sonner une alarme .

    Received quickly. But it doesn’t work. Tuya or smartlife does not detect the sensor. To flee

  78. 5 out of 5


    Install very fast. Batteries in it and connect via “smart life” app. Very satisfied.

  79. 5 out of 5


    The item was exactly as described and works like a charm. Would recommend store as everything was in order.

  80. 5 out of 5


    pros: works with tuya app as expected. reaction time is sometimes up to 4-5 seconds but it is not critical cons: unfortunately includes chineese XR3 chip that is not possible to flash with custom firmware neither ESPHome nor Tasmota ( not compatible with esp826X ) so I was not able to integrate it with Home assistant – Tuya integration still does not support door sensors 🙁

  81. 5 out of 5


    I arrive 10 days, it works perfectly and at first. I ‘ve connected it to smart Life and Alexa recognized it immediately. It seems to me that price quality is difficult to improve. The only catch is that the pieces have to be very close for you to detect. I recommend, I haven’t linked any other devices yet, but I think it’ll be easy.

    All right, packaged, date of receipt, product according to the offer on the WEB. Remark: I have Wifi 2,4 and 5,4 GHz. To set it up I connected to the 2,4 GHz Wifi on the iPhone 7 and IOS 14,3, and I didn’t get the Smart Life app, ni, yours to connect to the sensor. I tried a table and Android 4.3 getting it linked and once linked to this system the sensor appeared in the iPhone 7 Smart Life App.
