## Long description

Homematic IP HmIP‑SWDM is a compact wireless door/window sensor in white designed for monitoring openings and closings in smart homes. The device communicates via RF and is powered by two 1.5 V AAA (LR03) batteries with a typical battery life of up to 48 months. Its slim housing (102×25×18 mm) is suitable for mounting on door and window frames and can be integrated into Homematic IP systems for status display, automation triggers and alarm functions.
Advantages
The sensor provides immediate detection of door and window state changes and transmits updates to the Homematic IP system or app. It supports energy-saving scenarios by interacting with radiator thermostats to lower room temperature during ventilation. Installation is flexible: the contact and magnet can be fixed using the supplied screws or adhesive strips, and the adhesive can be removed residue-free, making the device suitable for rented properties. Stand-alone pairing and integration via an Access Point are both supported.
Suitable for
 Open/close detection on doors and windows
 Triggering intrusion alerts and alarm sirens
 Automations with radiator thermostats for energy saving during ventilation
 Status monitoring via Homematic IP app while at home or away

 Operating range: up to 200 m outdoors (typical, depending on environment)
 Dimensions: 102 × 25 × 18 mm

 Mounting options: screws or adhesive strips; adhesive removable without residue
How to use
Place the contact and the magnet on the fixed frame and moving part of a door or window so that they align when closed. Pair the sensor with a Homematic IP Access Point for full configuration and status display in the Homematic IP app, or use stand-alone push-to-pair mode for direct pairing with compatible radiator thermostats. Insert two AAA batteries, observe correct polarity, and secure the housing. Test operation via the app or by opening and closing the door/window to confirm detection and any linked automations or alarm responses.
Usage recommendations
For reliable detection and radio performance, install the sensor on clean, dry surfaces and ensure the contact and magnet are aligned within the manufacturer’s recommended spacing. When used with radiator thermostats, define the desired setback temperature for ventilation scenarios in the Homematic IP app. Replace batteries before the end of service life to maintain uninterrupted monitoring and automation functions.
