The Loxone Tree Extension allows the integration of various devices like sensors, actuator or lighting products that are equipped with the Loxone Tree technology.
The Miniserver features an integrated Tree interface. The Tree Extension is equipped with two Tree interfaces.
A Tree interface including wiring and devices connected to it is called a Branch. Up to 50 Tree devices can be connected per Branch with a maximum total length of 500m/1640ft.

The Tree Extension is installed on a DIN rail in a suitable enclosure.
Connect the power supply and Link communication to the Miniserver.
The Tree devices are connected to one of the two Tree interfaces. Please follow the detailed instructions for connecting Tree devices below.
The Extension starts after switching on the power supply, and the status LED will flash orange after a short time when the connection to the Miniserver is established.
Connecting Tree Devices↑
Connect the Tree Devices to the Tree Interface of the Miniserver or Tree Extension. Up to 50 Tree Devices can be connected per branch with a maximum total length of 500m/1640ft. There must be no connection between different Tree branches.
The following diagram shows the wiring of several Tree devices connected to a Tree Extension.
The following topologies are permitted for wiring:
The Loxone Tree cable is used for wiring, it contains the Tree communication lines as well as the lines for the 24VDC power supply in the corresponding colors. For devices with higher power requirements such as Tree lighting products, the Tree cable also contains a pair of wires with 1.5mm² cross-section (AWG16) for power supply.
We recommend running one Tree cable from the panel per room and then branching off to the individual Tree devices in that room. This corresponds to a Tree topology.
Within the enclosure, panel wire is also used for wiring.
Devices that communicate with each other have to share a common GND. This is necessary if more than one power supply is used. (e.g. in a sub-panel, or if separate power supplies are used for lighting). For this all power supply's GND (negative) must to be interconnected. This connection is crucial for reliable data transmission.
The max. length of 500m applies to the communication lines of a Tree Branch, not to the line length of the 24V power supply. Especially Tree light fixtures have a higher power requirement that can lead to voltage drop on the 24V lines, and depending on the topology, the achievable line length can be significantly shorter.
For longer distances or higher loads, either use a separate power supply closer to the loads, or split the loads across multiple home runs. Alternatively, a separate line with a higher cross-section can be installed.
Pairing Tree Devices↑
To search for Tree devices, first click on a Tree Extension in Loxone Config, and then activate Tree Device Search.
The window that opens will list all connected Tree devices that are not yet part of the program:
If you select a device here, it will identify itself in different ways. Devices with a status LED will flash it, light fixtures pulse a white light, other devices such as the Loxone Touch emit an audible click. This allows you to assign and name the devices correctly.
Select the desired device, assign a name, room and installation location and add it to the programming using the Pair Device or + button.
The right window lists all the devices that are currently part of the program. You can display them by clicking the button Show my Tree devices. You can also replace an existing device with a new device of the same type that was found in the search. This is useful when a device needs to be replaced or devices are added to a pre-configured program. Select the device to be added and the device to be replaced. By clicking on the button with the arrow pointing right, the old device is replaced with the new one in the program.
To apply the changes, save the program in the Miniserver.
Now the added devices are ready for use and the functions are available in the Periphery Tree in Loxone Config.
The Loxone App, under Settings, also supports searching for and pairing Tree devices. (Loxone Config version 11.1 and up)
Update and diagnostics for Tree devices↑
If an Update is necessary for a Tree device, they are highlighted orange in Device Status. This often happens after a recent update of the Miniserver or when adding devices with an older firmware version.
The Miniserver automatically updates Tree devices in the background, the devices generally remain operational. However, there can be delays in communication. In rare cases, some functions of Tree devices may not be available until the update is completed.
The following options are available for Diagnostics:
1. The Status LED of a device allows for quick error checks.
Red flashing: No connection to Miniserver via Tree interface, check wiring and Miniserver.
Orange flashing: Connection to Miniserver ok, but device not yet added to the program.
Green flashing (continuous or 3 times, then off): Everything okay, device is online.
Quick red/green flashing: Device was selected in Loxone Config and is identifying.
Not flashing: Normal operation (the status LED is off or was switched off, depending on the device)
2. Tree Diagnostics provides a more detailed analysis. First connect to the Miniserver, select a device with Tree interface, and then click on the button Tree Diagnostics.
The Tree devices are now listed in the Tree Diagnostics window. Diagnostic data is transmitted continuously, and can be used to detect any errors. Any errors are displayed along with suggested solutions.
Temporary errors (e.g. poor contact, potential difference) can also be detected by packet loss.
Depending on the number and type of devices that show errors in diagnostics, the error can be localized. It is helpful to know the wiring of the installation well. Check whether only devices on a particular Branch, devices in a certain room, or devices beyond a certain point in the wiring are affected. This will help localize and identify possible causes such as faulty connections or reversed data lines.
If errors occur only sporadically, monitor Tree Diagnostics for some time. Based on the timing of errors, it may be possible to establish a connection with another event. A missing GND connection can also be the cause for intermittent errors.
|Online status Tree Extension||Digital|
|Serial number||Specifies the serial number of the device.
For Extensions: 'Auto' may only be used if only one Extension of this type is being used.
|Switch Off Status LEDs||If ticked, the status LEDs on the following devices are switched off during normal operation:
Valve Actuator Tree
RGBW 24V Dimmer Tree
In the event of a fault, the devices will still alert you using their status LEDs.
|Monitor Online Status||If ticked you will be notified via the Loxone App or the Loxone Cloud Mailer when the device is no longer reachable, e.g. goes offline.||-|
The installation must be carried out by a qualified technician in accordance with all applicable regulations.
The installation requires a suitable enclosure to ensure protection against contact, water and dust.
The device must not be used as part of safety-critical systems.
