How to set an output in the template block to send data to MQTT (out)

[Melih]

Hi,

my goal is to get an request from mqtt to extend the cylinder (created in SVG), in the template block, when the cylinder is extended, it must send a data to MQTT. But I actually don't know how to set an output there.
I tried with $scope.msg.action, $scope.msg.payload, but still, the function block after the template block can't recognize the data I filled in the template.

How template looks like:

What do I need to write here to write stuffs from template into mqtt block?

Thank you!

Sincerely

Bit incomplete but if you are trying to send a msg with $scope.msg.<WhatShouldIdo?> try $scope.send({payload: "HALLO"})
