3 Function and device overview
The Homematic IP Rain Sensor detects even the smallest
amounts of rain or snow via the integrated sensor area.
As soon as rainfall begins, the sensor transmits the
information to connected Homematic IP devices as well
as the Homematic IP smartphone app. Thus, for example
the awning can be retracted automatically in connection
with a Homematic IP Shutter Actuator. The warning via the
app and push-notification on the smartphone can be used
to react early in the event of rain to prevent any damage
caused by open roof windows, for example.
The integrated sensor heating ensures that the sensor
area dries immediately. This avoids functional limitations
caused by dew and ice formation. Thanks to the wide
temperature range and waterproof housing (IP44), it can
be used even under extreme conditions of -20 to +55 °C.
