Hi!
I’m trying to create my first blueprint, and can’t figure out how to make a calculation based on the sensor illumination. I come from a Homey environment where I used a similar calculation, and now I want to transform it to HA.
It works if I set the brightness_pct to like 50, but my calculation doesn’t work. I’m not sure how to do this, or if it’s even possible? Is this possible? I tried with both wait_template and to make the calculation within the brightness_pct settings, but none of them works. What am I missing here? 
blueprint:
name: Set dim level on selected light source based on illumination value when motion is triggered
description:
"Dims light based on motion detection and illumination source. You
can choose to dim the light up when the illumination goes up, or dim the light
down when the illumination goes up. The dim level will be set by ten (10) steps
at a time.\n\n
Required entities:\n
- Motion sensor (single sensor or group)\n
- Illuminance sensor\n
- Light source\n
- Max illumination value\n
- Max dim level\n\n
Optional entities:\n
- Turn off wait time\n
- Blocking entity\n
- Run before time\n
- Run after time\n\n
Optional features:\n
- You can define a blocking entity, which blocks the automation from running when
this entity's state is on.\n
- Time limits can be defined to limit the time before and/or after the automation id triggered.\n
- You can use the Turn off wait time input to turn off the light automatically."
