Have you put the script into Lights - Switches - Scenes - Scripts? If you use the light entity and use Transition - ON will that work?

Seems like you’re using a scene, not a script, that’s probably why it looks like the script isn’t working. Swap it out for the script and give it another try

Hi @Blacky ,
First of all great blueprint. But it appears it doesn´t work for me. 
I´ve checked everything. The YAML and all that and it seems it´s correctly setup or I´m missing something terribly obvious. The automation simply doesn´t trigger.
Platform of the media player is Amazon Fire TV Cube.
I double checked and even added all possible media player combinations but the automation never triggers. I can see the media_player indicating the status of “Playing” but nothing.
Here´s my yaml
alias: Movie Night Plex

use_blueprint:
path: Blackshome/sensor-light-add-on.yaml
input:
trigger_entities:
- media_player.fire_tv

- light.living_room_ceiling_back
intermission_include_light_control:
- use_transition
include_start_turn_off: enable_start_turn_off
include_intermission: intermission_enable
Can you give me some feedback on what might be wrong?
Really appreciate your time.
Thank you.
Just quickly looking at it (sorry big day today) you have no Movie Lights. Just add a light in light.hue_lightstrip_plus_1_2 and set it to 0% brightness (that will turn it OFF).
Let us know how you go. Like this… I have also changed your Intermission Lights and Lights ON at End so you can see how it works. Adjust as required.

Thank you @Blacky . That was the issue.
A minor feedback regarding the app selection. There are two options available. One for Chromecast and another for Apple TV. In my case I’m using Plex on Fire TV Cube. For Fire TV Cube I used the application name “com.plexapp.android”.
With that said, marvelous automation blueprint. Thank you again for your help and this fine blueprint.
Here’s my updated config:

Omg I feel like such an idiot. well I selected the right one that was really a posting mistake as I tried a lot of stuff. I copied the blueprint and the only way I can get it to work is like this.
action: script.ashley_s_light_fader
data:
light: light.family_lamps
lampBrightnessScale: zeroToTwoFiftyFive
transitionTime:
hours: 0
minutes: 0
seconds: 30
easingTypeInput: easeInOutSine
endBrightnessPercent: 5
endBrightnessEntityScale: zeroToTwoFiftyFive
autoCancelThreshold: 10
shouldStopIfTheLampIsTurnedOffDuringTheFade: true
shouldResetTheStopEntityToOffAtStart: false
shouldInvertTheValueOfTheStopEntity: false
minimumStepDelayInMilliseconds: 100
shouldTryToUseNativeLampTransitionsToo: true
isDebugMode: false
Ok I got it to work by having a script call the main script which is what I think you said.
