The Aeotec Door Window Sensor 8 (ZWA055-C) is a Z-Wave 800 Series door and window, tilt, temperature, and humidity sensor.
The device uses a built-in reed sensor to monitor the position of the included magnet and reports whether a door or window is open or closed. The integrated three-axis sensor can also detect changes in tilt, making it suitable for monitoring tilt-and-turn windows, roof windows, and garage doors.
The Door Window Sensor 8 also measures temperature and relative humidity. Based on the measured values, it calculates the dew point and can report a mould risk warning when humidity levels are high. The opening status and environmental data can be used in heating, cooling, ventilation, lighting, and security automations.
The device supports Z-Wave 800 Series hardware, Z-Wave Plus Long Range communication, S2 encryption, and SmartStart inclusion. It can be powered by one CR14250 battery or a 5 V USB-C power supply. It is compatible with Home Assistant, SmartThings, Homey, FIBARO, and other compatible Z-Wave systems.
