Item description Special featuresThis smart sensor detects whether your door or window is being opened or closed and sends this information to your Nedis SmartLife application.A Nedis Zigbee gateway (WIFIZBxxx) is required for this.This allows you to automate many different actions, such as sending a notification when someone is in the house or reminding you when a door or window has been left open.By combining this sensor with other products in the Nedis SmartLife application, you can activate any additional Nedis SmartLife product when a door is opened (e.g. light, smart plug, or alarm) or switch off the heating or air conditioning when a door is open.Thanks to its compact size and the included battery with a lifespan of up to one year (with six activations per day), you can place this sensor anywhere you want (within a range of approximately 30 meters from the Zigbee gateway).
