Product information

Description

The Homematic IP 142800A0 door/window sensor is a wireless magnetic contact sensor designed to detect opening and closing events on doors and windows. It communicates on the 868.3/869.525 MHz band and is powered by a 1.5 V battery. With compact dimensions (32 mm width, 16 mm depth, 143 mm height) the sensor can be mounted unobtrusively on frames and sashes to provide reliable state information to a Homematic IP system or compatible gateway.

Advantages

The sensor provides reliable contact detection with low power consumption thanks to battery operation and optimized radio communication. Its slim housing and small footprint make installation discreet on narrow frames and small windows. Operation on standard frequencies ensures compatibility with Homematic IP components and supports secure wireless signaling for event notification and automation triggers.

How to use

Mount the sensor’s main body on the fixed frame and the magnet on the moving sash or leaf so that the two parts align when the door or window is closed. Insert the 1.5 V battery following polarity markings and pair the device with a Homematic IP access point or compatible gateway according to the gateway’s inclusion procedure. After successful pairing, configure desired notifications, automations or alarm responses in the system interface. Test the installation by opening and closing the fitted door or window and verifying the reported status changes in the control app or gateway.
