As the name suggests, the RAIN PRO is a fully functional wireless weather station, with a focus on measuring rainfall. The package includes two wireless transmitters: a container for measuring the amount of rain and a combined sensor for determining outdoor temperature and humidity. The measurements are transmitted wirelessly to the base station in your living space. Find a suitable location outdoors for the measuring container, where rain can fall freely from all sides. When it starts to rain, raindrops will blink on the weather station's display, the measurement cylinder graphic will slowly fill up, and the exact amount of rain will be shown. The 24-hour rain alarm will notify you as soon as more precipitation falls than the threshold you have set. After operating the station for an extended period, you can view various summarized time periods, such as the rainfall in the last 24 hours, the last 7 days, or the total rainfall since installation. Rainfall amounts for the last 12 months can be accessed and compared individually.

Additionally, the RAIN PRO provides other desirable information. Based on the air pressure changes measured by the integrated barometer, the weather symbol gives a forecast for the upcoming weather. To monitor the indoor climate, temperature and humidity are displayed. The current time and the complete date with the day of the week are received via the DCF 77 radio signal.

Two additional sensors for temperature and humidity control, for example in the children's room or garage, can be connected.
