Loxone Tree

Loxone Tree technology reduces the amount of cabling needed for your
smart home installation. Our Tree technology makes integration
fast and easy.


The update of Tree devices is performed automatically in the background. The device will still function while this update takes place. If miniserver is restarted during the update process the update will need to start again when power is restored.

This may take up to an hour.

The device version can be checked in the ‘device status’ window. If the version number is highlighted green then the device is up to date.

For full information on wiring Loxone Tree please see here.

With Loxone Tree there are many wiring topologies that can be used.
The cable required is Cat7 Cable.

A Maximum of 50 devices can be connected on each tree branch.
The maximum length of cable is 500m per branch.

To commissioning the Tree devices connect the 24V power (orange/orange-white) and the Tree (green/green-white).
Ensure the correct punch down tool is used to terminate cable (Valve Actuator Tree).


To add Tree devices, you first need to wire them up and have the devices connected back to one of the Loxone Tree Extension Branches.

The LED on the Tree device will flash orange when the wiring is all correct. If the device does not flash orange check the wiring of the devices.

Click the branch you wish to add the device to in the periphery tree within Config, you will see the top ribbon bar change to show Tree related setups.
