02.05.2024: There are currently commissioning problems with the Vaillant gateways VR920, VR921 and VR940f in the form of EE-Bus devices displayed permanently offline in the Loxone Config. There is no basic communication even though the highest possible update has been carried out in the myVaillant app. The process is currently being checked at Vaillant and Vaillant Support has also been informed. 

EEBUS is an open standard to connect devices across manufacturers and industries. The primary goal is to increase energy efficiency.
For the latest information on applications and capabilities, visit the website of the EEBus Initiative.

EEBUS specifies various UseCases.
The Loxone system currently only supports the HVAC UseCase.
The devices are integrated via the network using the SHIP protocol.

The Miniserver Gen. 1 does not support EEBUS!

Vaillant offers EEBUS enabled heat pumps, which can be integrated as described in the configuration example.

Configuration Example


The current Miniserver is used.
EEBUS devices are connected to the network, configured and accessible.
The EEBUS feature or interface on the device is enabled and authorised.

Example Vaillant Heat Pump

First, EEBUS is enabled in the settings menu of the unit's multiMATIC app:

Then a Network Device Search is started in Loxone Config, and once the device is found it will be listed in the search results:

Use the + button to add the device to the configuration and save the program to the Miniserver.

Next, communication with the Miniserver must be approved using the multiMATIC app, where the Miniserver should already be listed among the available devices.
Select the Miniserver, and then add it to the list of trusted devices:

The device should now be marked green in the Periphery tree of Loxone Config.
You can then search for available inputs and outputs by clicking on the Find periphery button:

Now the available Inputs and Outputs are listed in the Periphery tree and ready for use in configuration:
