I Tried using the Template Editor, as I have done many time before.
Can someone point out what Ime doing wrong with the editor in this case,
As the code I’m NOW posting in it is known to be working.
Or is it just that this Tool does not work for MQTT blocks of code.
Only Template: Blocks?
It only works for templates. It doesn’t support what you are trying to do. Templates added to the editor work exactly the same as if they were rendered in code.
