Trying to create a script to adjust brightness of selected Light(s) over a certain time. I’ve re-created this script multiple times and now it’s to the point I want to throw out Home Assistant and go back to Smartthings.
I’m trying to create a wake up routine that will brighten my lights and increase my Bose Soundtouch volume over a certain amount of time. Currently, I am writing the script for the lights. It will also be used by other automations so I’m trying to make it not as rigid.
For those about to say, “Use the Light:Turn On Service”, it stopped working. Transition doesn’t work anymore. If I set it to Transition of 10 seconds, with a brightness of 100%, and activate it. It goes straight to 100% in under a second, Every Time. And no, I didn’t go in and mess with the coding for the service. It stopped working a while back for some unknown reason thus, I keep waking up to my lights turning on to 100% the moment my alarm goes off. Thus, why I’m ready to chuck the whole thing out the window.
Example of the code is to Call Service
Select Lights, set initial brightness, set final brightness, set duration (transition).
alias: Gradual Light Brightness Increase
fields:
target_lights:
name: Target lights
description: Target lights to have brightness adjusted
required: true
example: light.ceiling_fan
selector:
entity:
domain: light
multiple: true
initial_brightness:
name: Initial Brightness
description: Initial brightness percentage
required: true
default: 10
example: "10"
selector:
number:
max: 100
min: 0
step: 1
mode: slider
final_brightness:
name: Target Brightness
description: Target brightness
required: true
default: 100
example: "100"
selector:
number:
max: 100
min: 0
step: 1
mode: slider
duration:
name: Fade duration
description: Length of time in seconds the fade should take.
required: true
default: 5
example: "5"
selector:
number:
mode: box
min: 0
max: 100000
unit_of_measurement: s
delay:
name: Delay
description: Delay between adjustments.
required: true
default: 2
example: "2"
selector:
number:
mode: box
min: 0
max: 10
variables:
initial_time: "{{ now() }}" #Time script starts
final_time: "{{ initial_time + timedelta(seconds=duration) }}" #Time script should stop by
brightness_range: "{{ final_brightness - initial_brightness }}"
brightness_increment: "{{ brightness_range / duration }}"
duration: "{{ duration | int }}"
delay: "{{ delay | int }}"
delay_time: 00:00:{{ delay }} #formatting
duration_left: "{{ duration }}" #Duration left set = duration initially
sequence:
- service: light.turn_on #Set lights to initial brightness
data_template:
entity_id: "{{ target_lights }}"
brightness_pct: "{{ initial_brightness }}"
- repeat:
until: "{{ ( duration_left <= 0 ) or ( now() >= final_time ) }}"
sequence:
- delay: "{{ delay_time }}"
- variables: #Calculate brightness setpoint for this iteration
current_duration: "{{ loop.index0 * delay }}"
current_brightness: "{{ initial_brightness + brightness_increment * current_duration | round(0) }}"
- service: light.turn_on
data_template:
entity_id: "{{ target_lights }}"
brightness_pct: "{{ current_brightness }}"
- variables: #calculate time left
duration_left: "{{ duration_left - delay }}"
I got it to set the Initial light brightness before, but after that it would give me an issue about the loop being undefined even though it was and there was no syntax issues I could find. I’ve tinkered and messed with this too much that I’m at my wits end.
This was the latest error code I saw when trying to get this thing to work.
