Overview MQTT output

The function block MQTT output is used to publish values from the controller as an MQTT message. In the settings dialog a list is created with the inputs button: one topic per line. One input is created for every line. When the value at the input changes, the message is sent.

Inputs
E0 Value 0 Value of the first line of the list. One further input is created for every further line (E1, E2 and so on).

Parameters

Inputs Opens the list of topics. Per line the topic is entered under which the value is published.

Data type Format of the sent value: Integer as a whole number, Float with decimal places, True/False and On/Off as text for bit values.

Retain The broker remembers the value sent last and passes it on to newly connected participants. Without retain, a participant only receives a value on the next change.

Update on startup Sends all values once when the controller starts, even if nothing has changed.
