The wind speed, precipitation, twilight and temperature can be measured and evaluated with the new KNX weather station Standard. In addition, three brightness sensors offset 90º from one another determine the brightness in different directions. Individual or collective evaluation of the sensors is possible. The weather station is installed on the building exterior, for example on the roof, and connected to the KNX system.
Two different limit values can be taught in per sensor. A teach-in function allows for adoption of a current measurement value as the limit value.
To increase functional reliability, the weather station monitors its own major functions and reports corresponding faults automatically via message objects on the bus. Operation without a 24 V additional power supply is possible. In this case, rain detection is deactivated and the corresponding safety objects are activated continuously.
