Nedis Smart Door/Window Sensor

This smart sensor will recognize whether your door or window is opened or closed and sends this information to your SmartLife application. To do this, a Zigbee gateway (WIFIZBxxx) is required.This enables you to do many different things automatically, such as notifying you when someone is in your house or send you a reminder when a door or window is left open.By combining this sensor with other products in the SmartLife application, you can trigger any additional SmartLife product on opening a door (e.g. light, smart plug or siren) or switch off a heater or air conditioner when the door is open.Its compact size and the included battery with a lifetime of up to one year (with six triggers per day) lets you place this sensor anywhere you want (within a range of approximately 30 metres of the Zigbee gateway).
