Description

A door opens while you are away, and your phone knows within seconds. This compact Wi-Fi sensor pairs with the Smart Life app, sounds a 90dB siren on the spot and keeps a timestamped record of every open and close.

Get instant smart alerts and a 90dB siren the moment your door or window opens

Solves
  • unnoticed break-ins through doors or windows
  • no record of when doors were opened or closed
  • forgetting to check on entryways remotely
  • dead batteries going unnoticed

A door opens while you're away. Your phone knows within seconds.

Stick the compact sensor beside any door or window and pair it with the Smart Life app. The moment the contact breaks, your phone gets a push alert and a 90dB siren sounds on the spot, so an unnoticed entry stops being unnoticed.

An alarm that reaches you wherever you are

A 90dB siren you can hear from the street

The siren sounds the instant the magnetic contact breaks. At 90dB, it is loud enough to make an intruder at a door or window think twice and leave. You do not need to be home to hear it, because the push alert reaches your phone at the same moment.

Every entry, logged and timestamped

The Smart Life app records each open and close with a time stamp. Scroll back to see when the back door opened while the kids were at school, or confirm that the patio window was shut before bed.

A low battery reminder before it goes quiet

A dead battery would leave the entry unwatched without any warning. The app sends a low battery reminder so you can swap the battery while the sensor is still working, and the entry stays covered.

Pair in minutes with the Smart Life app

  1. 1
    Install the Smart Life app

    Create an account and sign in on your phone.

  2. 2
    Pair the sensor over 2.4GHz Wi-Fi

    Add a device in the app and follow the prompts. Once paired, the sensor joins your home network.

  3. 3
    Mount the sensor on the frame

    Fix the main unit to the door frame or window frame, then attach the magnetic contact strip to the moving door or sash.

  4. 4
    Align the magnet with the sensor

    Keep the strip close to the sensor when the door is shut. A large gap can cause false opens.

Questions and answers

Do I need a separate hub, or does it connect straight to Wi-Fi?
w
Wanelo · seller

No hub is needed. The sensor connects directly to your home Wi-Fi and sends alerts to the Smart Life app on your phone. Pair it on a 2.4GHz network, since many Tuya sensors will not join a 5GHz-only setup.

Does it work with the Tuya and Smart Life apps?
w
Wanelo · seller

Yes. The sensor is powered by Tuya and set up through the Smart Life app. Once paired, the app handles push alerts, the open and close log and the low battery reminder.

Can I mount it on a rental door without drilling?
w
Wanelo · seller

The contact sensor and magnet strip are built to sit on a door frame and the door itself. Mount them with the included hardware or a method your landlord allows. Check your lease before you put anything on the frame.

How do I know when the battery is low?
w
Wanelo · seller

The sensor sends a low battery reminder to the app. Turn on push notifications for the app so the reminder reaches your phone. Replace the battery as soon as it appears, since a dead battery stops the siren and alerts.

Is a plastic body reliable enough for a security sensor?
w
Wanelo · seller

The housing is plastic, but the job is simple: a magnetic contact that breaks when the door moves, a siren, and a Wi-Fi alert. What matters most is alignment, so keep the magnet strip close to the sensor when the door is closed.

Is it worth it compared with a standalone chime sensor?
w
Wanelo · seller

A chime sensor only sounds a tone in the house. This unit adds a 90dB siren, a phone alert and a logged history in one device. Adding a second sensor covers a second entry point, and there is no hub to buy.
