Hi and thank you very much for your contribution!

I am completely confused by my own code (maybe because it is ugly, but i failed to refactor it to a more readable form more than once ;)).

What exactly is this doing? I see that after the property has been set in the renderingConfig that the following (before your change 'dead') code will be executed:

if (renderingConfig.rotationPercent !== undefined) {
    rotationPercent[currentContext] = renderingConfig.rotationPercent
  }

This updates the current rotationPercent value for a knob. But why? Can you describe your use-case? (I know, I added the code somewhen but I am not sure what the intention was)?

Hello! I am trying to control a motorized shade. I can call set_position with JSON

{
  "position": <some percentage>
}

Therefore I would need to know the percentage.

Initially I wanted to read from the state, but the code is really ugly:

{
  "position": "{% raw %}{{{% endraw %} state_attr('<some entity>', 'current_position') +  ({{ticks}}) {%raw%}}}{%endraw%}"
}

So I thought if I can keep the rotationPercent in sync with Home Assistant's state, the code can be simplified

{
  "position": "{{ rotationPercent }}"
}

I am also exploring an "optimistic update" feature, where if you rotate the knob, the percentage is immediately reflected on the screen, until overridden by Home Assistant's state. This is also for the motorized shades, since those things are slow, and if you rotate the knob, you have no idea what value you set it to.
