Miniserver Go Gen. 1

The Loxone Miniserver Go serves as central control unit for all kinds of automation tasks.

The replaceable microSD card contains the operating system as well as the user programming and settings. The LAN interface is used for programming and the integrated web server allows the control of the system via a web interface or the Loxone App.

An Air Base Extension for connecting devices via Loxone Air wireless technology is already integrated.

Up to 30 Extensions can be added to the Miniserver Go via the Link interface to add additional functions such as inputs, outputs or interfaces.

Install the unit in a place where it is protected from water, dirt and possible damage. The bracket on the back allows for screw mounting.

Plug the included power supply into the Micro-USB connector.

Via the LAN port the Miniserver is connected to the local network or a WiFi router.

The Miniserver Go starts after the power supply is connected, and will be operational within a few seconds.
Once the boot up process is complete, the status LED will be permanently lit.
The LEDs on the RJ45 port are disabled on the Miniserver Go and are off during operation.

When starting for the first time with factory settings, the Miniserver is assigned an IP address by the router via DHCP. If there is no DHCP server in your network, or if the Miniserver is connected directly to a PC, its default IP address is In this case, assign a matching IP address to the PC to make the connection possible.
Zeroconf link-local addressing is not supported by the Miniserver Go Gen. 1.

You can then search for the Miniserver in Loxone Config and connect. The factory settings for user and password are: admin/admin

Then follow the instructions for the Initial Setup to create your new project with the Miniserver.

Connecting Extensions

Up to 30 extensions can be connected to the Miniserver Go according to the following diagram:

Connect the Extensions to the Miniserver Go by daisy-chaining the Link interfaces. Since the Extensions are connected to a separate power supply, GND must also be connected. This connection is crucial for reliable data transmission.

One twisted pair of a CAT5/6/7 cable can be used to wire the Link throughout a building. We recommend using the blue/white pair.

The Link interface is terminated at the last Extension using the 120 Ohm resistor that is included with the Miniserver.

Pairing Extensions

To add Extensions, first click on the Miniserver in Loxone Config, and then on Extension Search.
Link Search will now list all Extensions that are connected to the Miniserver. Select the desired Extension and add it to the programming using the + button. Use the button "Create all devices" to simply add all Extensions that were found.

When highlighting one of the Extensions, its status LED will start flashing. This allows you to easily identify the devices.

With Replace device you can replace an existing Extension with another Extension of the same type. This is useful when a device needs to be replaced or Extensions are added to a pre-configured program. Alternatively, you can change the serial number in the properties of an Extension that is already part of the program.

To apply the changes, save the program in the Miniserver.

Now the added Extensions are ready for use and the functions are available for programming in the Periphery Tree in Loxone Config.

Update and diagnostics of Extensions

If an Update is necessary for Extensions, they are highlighted orange in Device Status. This often happens after a recent update of the Miniserver or when adding Extensions with an older firmware version.

The Miniserver automatically updates the Extensions in the background, the Extensions generally remain operational. However, there can be delays in communication. In rare cases, some functions of Extensions may not be available until the update is completed.

The following options are available for Diagnostics:

1. The Status LED of an Extension allows for quick error checks.
Red flashing: No connection to Miniserver, check wiring and Miniserver.
Orange flashing: Connection to Miniserver ok, but Extension not yet added to the program.
Green flashing: Everything okay, Extension is online.
Orange/Red flashing: Transmitting update.
Quick red/green flashing: Extension was selected in Loxone Config and is identifying.
Not flashing: Check power supply.

2. Link Diagnostics provides a more detailed analysis. First connect to the Miniserver, select a device with Link interface, and then click on the button Link Diagnostics.

The Extensions are now listed in the Link Diagnostics window. Diagnostic data is transmitted continuously, and can be used to detect any errors. Any errors are displayed accordingly. Please monitor the Link Diagnostics for a while, even temporary errors (e.g. poor contact, potential difference) can be detected by packet loss.
