Add variables to the MQTT data source
Enter a name for the variable. Click on “Add” to create the variable.
The window remains open to create further variables. “Close” the window to end the input.
The variable can be created manually by entering a “Topic“.
It is easier if you click on “Search” to select the existing variables using the “Search topic” function.
The “Search Topic” works according to a tree structure. If only one “#” is entered, EVERYTHING is searched, which can take some time.
Enter the desired topic (*name of the topic* *slash* *#*) and click on “Refresh“. The topic is then searched for the variables (all variables are strings). Select the desired variables and click on “Import” to create the selected variables and close the window.
The variables for the MQTT data source have been successfully created and can now be used.
MQTT address syntax for quick entry
MQTT variables can also be added with a quick entry.

In general, the following syntax applies to MQTT addresses:
- [Datentyp].[Topic]
