MQTT elements

Elements "MQTT Value Input" and "MQTT Value Output"

In addition to the "Value Input" and "Value Output" elements for KNX data points, the LOGIC EDITOR provides dedicated elements for MQTT data points.

The "MQTT Value Input" and "MQTT Value Output" elements serve as an interface within logic groups to the configured MQTT data points.

The created MQTT data points are used within logic groups in a similar way to KNX data points and enable the exchange of values between an MQTT broker and the KNX system.

LOGIC EDITOR element "MQTT Value Input"

The MQTT Value Input is used to receive values from an MQTT connection into the logic group. As soon as an MQTT message is received for the configured topic, the associated MQTT data point is updated and the value is available within the logic for further processing.

LOGIC EDITOR element "MQTT Value Output"

The MQTT Value Output is used to send values from the logic group to an MQTT connection. Changes to the logic value are published as an MQTT message to the configured topic via the assigned MQTT data point.

Linking an MQTT element in the logic group

These value inputs and outputs are added and configured within a logic group in the same way as all other inputs and outputs.

For each value input or value output, first select the required MQTT connection in the "MQTT CONNECTION"section. Afterwards, one of the MQTT data points assigned to this connection can be selected in the "DATA POINT"section.

This defines which MQTT topic is read into the logic or published from the logic (see following illustration).

MQTT element in the logic group

In the MQTT Value Output, all MQTT data points assigned to the selected MQTT connection can be used.
