The Avatto ZDS16 is a Zigbee 3.0 door and window sensor designed to keep you informed about the status of your home's entry points. By utilizing a main unit and a separate magnet, it detects whenever a door, window, or drawer is opened or closed through the separation of these two components. This white, compact device measures 65 x 26 x 12.7 mm and can be easily installed using the included adhesive, provided there is a gap of less than 10 mm between the parts. Integrated with the Smart Life app, the sensor sends remote alerts directly to your smartphone, ensuring you are aware of any activity in real time. To maintain reliable operation, the battery-powered system includes low-battery notifications and tamper alarms to warn you if the device is interfered with. Certified by CE, it is built to function in temperatures ranging from -10°C to +55°C, making it a dependable choice for various indoor environments.
