WTH can't I create a helper on top of another helper?

Month of "What the heck?!"

I’ve got a numeric helper entity. Turns out, none of these seem to support using numeric helpers as input:

  • Integral helper
  • Derivative helper
  • Min/max/mean/median helper
  • Threshold helper

Would be great to enable this. My scenario is a bathroom scale that I’ve semi-automated but the automation uses a numeric helper to store the last read weight. I’d like to set up a derivative sensor to alert me if the rate changes too much.

  1. Don’t forget to vote for your own request:-)
  2. While it is definitely doable, there is a caveat of circular dependency and requires a check before creating this. Let’s say helper A includes helper B and helper B includes helper C. Helper C cannot include helper A, it becomes an endless loop.
