Why PureNode Original
A WiFi door and window sensor that alerts your phone and sounds the alarm
Open a door, get a ping. The PureNode Smart Door & Window Sensor has a built-in 90 dBA siren with four volume levels, including mute. When the door or window opens, you get an instant alert in the Tuya Smart app and the alarm sounds at the door.
It joins your 2.4 GHz home WiFi directly, so you don't need a hub. Link it to Alexa or Google Home through Tuya Smart. Use it in automations too, like turning on a light when the front door opens or getting a reminder when a window is left open.
In the box: the sensor, magnet, 2 × AAA batteries, an adhesive pad and a printed user guide. Buy a single sensor, or choose a 2-Pack or 4-Pack to cover the front door, back door and windows.
PureNode is an Australian-owned smart home store run by Electro Oz Pty Ltd in Victoria. Every order ships free, and the sensor is backed by a 12-month warranty from delivery and our 14-day returns policy. Questions? Email info@purenode.com.au.
Made for the doors and windows you use every day
Where it fits
Front door alerts you can see and hear
The front door is the entry point most households care about most. Fit the PureNode Smart Door & Window Sensor to the frame and its magnet to the door, and the Tuya Smart app sends a notification the moment the door opens. That could be the kids arriving home from school, or a door that should have stayed shut. The built-in alarm is 90 dBA at 1 m with four volume levels, including mute, so you can have it sound at the door or keep alerts quiet and on your phone only. There is no hub and no wiring: it joins your 2.4 GHz WiFi and sets up in minutes.

Where it fits
Check your bedroom windows from your phone
Not sure you closed the bedroom window before heading out, or before a storm rolls in? Open the Tuya Smart app and see whether each window is open or closed, without walking through the house. The sensor sits on the window frame and the magnet on the moving sash, held in place by the included adhesive pad, so it suits rentals as well as homes you own. It is just as useful on a hot night when you want to know which windows are open. If the batteries run low, the sensor sends a warning to the app so it does not quietly stop working.

Where it fits
A sensor for sliding patio and balcony doors
Sliding patio and balcony doors are easy to leave unlatched and hard to check from another room. Fit the sensor to the frame and the magnet to the sliding panel, and your phone is notified whenever the door opens. It is handy for pets that wander out, young children heading outside, or a door left open while the air conditioner is running. Because the sensor uses WiFi, it also appears in Alexa and Google Home once you link them to Tuya Smart. It runs on two AAA alkaline batteries, which are included in the box.
