Creating JSON Object with Buttons, Sliders and Text Inputs

Hi there,

I was wondering how I can create a JSON Object wit some dynamic inputs (buttons, sliders, and texts).

I was trying to solve that in order to use a function to build the Object but unfortunately it does not work.

Does anybody have got created something like that? I would like to update this object every seconds and send it via MQTT to a broker (this is not an issue for me).

I am sharing my flow with you here .. it might be easily ridiculous for some of you but I am not that familiar at the moment with that.

You are referencing data such as payload.Stop. That should be msg.payload.Stop

It isn't JSON data, JSON is always a string. It is a javascript object.
