Weather Station Tree

The Weather Station Tree is used to capture data relevant for building automation such as wind speed, brightness, rain and temperature. By combining it with the Loxone Weather Service, additional weather data and forecasts are integrated.

The rain sensor heater is permanently active and prevents rain detection due to condensation. It is also used to dry the sensor after it has rained.

Mount the weather station in a location where wind, rain and brightness can be detected without interference.

The device is mounted as shown either to a post with the enclosed accessories, or directly to a wall. Ensure exact horizontal alignment.

Air turbulence caused by buildings or objects should be taken into consideration, as this can falsify the measurement depending on the wind direction. A good location is about 1,5 m above the roof. For flat roofs, positioning in the middle of the roof is recommended.

Measuring the air temperature and brightness at the same location is not always suitable due to the direct sunlight and the subsequent internal heating of the weather station. The installation location should therefore be chosen according to the application.

The Weather Station is not suitable for installation near the coast, as the salty air can lead to corrosion of the rain sensor

Connect the power supply (orange/white terminal) and Tree communication wires (green/white terminals).


Shortly after power-up, the status LED will blink orange if the wiring is correct and a connection to the Miniserver (Tree Extension is online) has been established.

Then follow the pairing procedure on the Tree Interface.

Storm warning threshold

The warning speed is set by the "Warning speed" value in the device's properties


Summary Description Unit Value Range
Brightness Provides the measured value of the current brightness lx 0...188000
Wind speed Provides the maximum wind speed measured during the last five seconds and only if the value has changed by at least 1 km/h. km/h 9...145
Temperature Provides the measured value of the integrated temperature sensor °
Rain Input is active when rain is detected - 0/1
Wind warning Input is active when the set wind speed is exceeded - 0/1
Sunshine Input is active when sunshine is detected. Sunshine is determined by the measured brightness, the sun's elevation, and the sunshine threshold setting. - 0/1

Diagnostic Inputs

Summary Description Unit Value Range
Online Status Weather Station Tree Indicates whether the device can be reached by the Miniserver.
Diagnostics for Air devices
Diagnostics for Tree devices
Diagnostics for Extensions
Digital 0/1


Summary Description Value Range Default Value
Monitor Online Status When selected, you will be notified via System Status or the Mailer if the device is no longer available or goes offline. - -
Serial Number Specifies the serial number of the device.
For Extensions: Enter 'Auto' to automatically pair an extension with unknown serial number.
This can only be used if there is only one Extension of the same type.
Save into the Miniserver, in order to pair the Extension.
Afterwards the program must be loaded from the Miniserver to transfer the actual serial number of the Extension into the program.
- -
Device type Tree device type - -
Storm Warning Threshold [km/h] Windspeed above which the storm warning will be triggered 0...150 35
Sunshine Threshold When the brightness exceeds the threshold calculated based on the sun angle, the sunshine input becomes active. - -

Safety Instructions

The installation must be carried out by a qualified technician in accordance with all applicable regulations.

Ensure that the device is level.

The device must not be used as part of safety-critical systems.
