MQTT Broker

2.1

The KNX SERVER 3 offers an MQTT broker, which can be used to connect not only the web server itself, but also

third-party devices that support this protocol or other KNX SERVERs, provided they are located in the same LAN.

This chapter explains how to set up the integrated MQTT broker of the KNX SERVER; after the described

procedures have been performed, it is typically necessary to activate the MQTT broker:

•

Configure third-party devices to operate the broker.

•

Configure the KNX SERVER itself to allow its objects to interact with the broker (internal client

connection).

•

Configure other KNX SERVERs to point to the Broker.

For the first point, you need to refer to the documentation of the devices you want to integrate with the Broker.

The second and third point are described in the next chapter in reverse order; if you do not use the integrated

Broker of the KNX SERVER, but only want to configure a connection to an external Broker, please jump directly to

the next chapter.
