Smart door and window sensor Koogeek Door/Window Sensor, DW1

Koogeek DW1 Door/Window Sensor monitors whether a door or window is open or closed. Its magnetic contact design gives a clear status for an entry or window as part of a smart home setup.

The sensor works with the Koogeek and Apple Home apps, where you can view the monitored opening’s state. HomeKit support also lets it send status change notifications and take part in scenes or automations with other HomeKit products, such as switching on a light when a door opens.

Setup uses Bluetooth and the app’s HomeKit pairing flow. The sensor runs on a replaceable CR2450 button battery. The set includes the sensor and magnet, adhesive backing, an extra set of adhesives, and a SIM removal tool for accessing the reset button.
