Technologies & Capabilities
Sensitive Rainfall Detection
The sensor measures precipitation the moment water contacts its surface, offering early alerts that help prevent damage to outdoor structures or open windows.
Outdoor-Ready, Weather-Resistant Housing
Built for long-term outdoor use, the sensor withstands rain, sun, and temperature fluctuations while maintaining consistent performance.
Smart Integrations Through Homematic IP
When paired with a Homematic IP Access Point or supported controller, the sensor can trigger automations such as closing shutters, retracting awnings, or pausing irrigation.
Easy Mounting For Ideal Exposure
The included mounting hardware allows installation on walls, poles, or roof edges so the detection surface receives accurate, unobstructed rainfall.
Frequently Asked Questions
What does the Homematic IP Rain Sensor detect?
It detects the presence of rainfall as soon as droplets reach the sensor surface, reporting precipitation events to your smart home platform.
Does this sensor require the Homematic IP Access Point?
The Access Point is recommended for full functionality, though the sensor may also work with compatible third-party controllers that support Homematic IP.
Where should I install the rain sensor?
Install it in an outdoor area with open sky exposure, such as a roof edge, pole, or exterior wall, to ensure accurate precipitation detection.
Can it trigger automations?
Yes. The sensor can activate actions such as closing windows, retracting awnings, adjusting irrigation systems, or sending alerts when rain begins.
How is the sensor powered?
The sensor runs on long-lasting batteries suitable for outdoor use. Battery life varies based on weather conditions and reporting frequency.
