Is it possible to have a script action that only occurs if a condition is true? I.e. only fade out pioneer receiver if it’s on?
boom_start_playlist:
sequence:
- service: script.turn_on
entity_id: script.pioneer_fade_to_zero
conditions:
condition: state
entity_id: media_player.pioneer_receiver
state: "on"
I get:
Error loading /config/configuration.yaml: mapping values are not allowed here
in “/config/scripts.yaml”, line 207, column 20
If the State Condition evaluates to true then the next action (script.turn_on) is executed. If it evaluates to false then nothing else happens and the script ends.
boom_start_playlist:
sequence:
- condition: state
entity_id: media_player.pioneer_receiver
state: "on"
- service: script.turn_on
entity_id: script.pioneer_fade_to_zero
If you need more flexibility (execute some service calls but not others) then I suggest you use choose.
@123, in your example all execution will stop if the condition is not met, correct? So what if there are subsequent steps that should run? The idea here is to fade the amp out if it’s on, then switch the playlist, and then fade it back up. But if it’s off, I want to turn it on and then fade it in. Here’s my full attempt…
boom_start_playlist:
sequence:
- service: script.turn_on
entity_id: script.pioneer_fade_to_zero
condition: state
entity_id: media_player.pioneer_receiver
state: "on"
- alias: "Wait until pioneer volume is zero"
wait_template: "{{ is_state_attr('media_player.pioneer_receiver','volume_level', 0) }}"
condition: state
entity_id: media_player.pioneer_receiver
state: "on"
- service: switch.turn_on
data:
entity_id:
- switch.harmony_hub_boom
condition: state
entity_id: media_player.boom_2
state: "off"
- delay: '00:00:03'
- service: squeezebox.call_method
data:
entity_id: media_player.boom_2
command: playlist
parameters:
- stop
- service: media_player.volume_set
data:
entity_id: media_player.pioneer_receiver
volume_level: '0.30'
- service: squeezebox.call_method
data:
entity_id: media_player.boom_2
command: playlist
parameters:
- play
- >-

- Playlist

So, in English…
Fade the amp if it’s on. Wait until it’s at 0 if it’s on. Turn it on if it’s off. Play the playlist.
As such, I want to attach conditions to the action items instead of halting all execution if a condition is not met.
Your original question didn’t mention anything about “subsequent steps”. That’s why I provided an example with a simple, inline State Condition. However, I did add that if you need more flexibility (meaning more than a simple inline condition) then you should use choose.
For example, this will execute script.pioneer_fade_to_zero only if the receiver is on. If it is off it immediately proceeds to the wait_template.
boom_start_playlist:
sequence:
- choose:
- conditions: "{{ is_state('media_player.pioneer_receiver', 'on') }}"
sequence:
- service: script.pioneer_fade_to_zero
- alias: "Wait until pioneer volume is zero"
wait_template: "{{ is_state_attr('media_player.pioneer_receiver','volume_level', 0) }}"
... etc ...
Final working script:
boom_start_playlist:
sequence:
- choose:
- conditions: "{{ is_state('media_player.pioneer_receiver', 'on') }}"
sequence:
- service: script.pioneer_fade_to_zero
- choose:
- conditions: "{{ is_state('media_player.pioneer_receiver', 'on') }}"
sequence:
- alias: "Wait until pioneer volume is zero"
wait_template: "{{ is_state_attr('media_player.pioneer_receiver','volume_level', 0) }}"
- choose:
- conditions: "{{ is_state('media_player.boom_2', 'playing') }}"
sequence:
- service: squeezebox.call_method
data:
entity_id: media_player.boom_2
command: stop
- choose:
- conditions: "{{ is_state('media_player.boom_2', 'off') }}"
sequence:
- service: switch.turn_on
data:
entity_id: switch.harmony_hub_boom
- service: squeezebox.call_method
data:
entity_id: media_player.boom_2
command: stop
- service: media_player.volume_set
data:
entity_id: media_player.pioneer_receiver
volume_level: '0.30'
- service: squeezebox.call_method
data:
entity_id: media_player.boom_2
command: playlist
parameters:
- play
- >-
https://a.playlist.url/example
- Playlist
- 5
And here is the fade out script…
pioneer_fade_to_zero:
sequence:
- alias: "Check the Pioneer is on, else we can bail."
condition: state
entity_id: media_player.pioneer_receiver
state: "on"
- alias: "Set Variables"
variables:
step: 0.01
- alias: "Turn the amp down AS LONG AS the conditions are true"
repeat:
while:
- condition: template
value_template: "{{ states.media_player.pioneer_receiver.attributes.volume_level | round(2) > 0 }}"
sequence:
- service: media_player.volume_set
data_template:
entity_id: media_player.pioneer_receiver
volume_level: >
{% set n = states.media_player.pioneer_receiver.attributes.volume_level %}
{{ n - step }}
- alias: "Set it to exactly zero in case of a math issue."
service : media_player.volume_set
data:
entity_id: media_player.pioneer_receiver
volume_level: 0
If the system is already playing a stream, it will fade down and then change streams and fade up. If it is off, it will turn on, and then start a stream and fade up. Squeezebox has a fade in parameter but not a fade out, hence the need to manually fade the receiver. Nice effect overall! Thanks, @123 !
Hi, I hava a similar problem and can’t find my failure.
I want to use a condition - input_number.xxx != 0 - in a script.
alias: script_irrigation_zone_1_start
sequence:
- service: rainbird.start_irrigation
data:
duration: '{{ states(''input_number.helper_irrigation_zone_1_duration'') | int }}'
entity_id: switch.irrigation_zone_1
condition: numeric-state
entity_id: input_number.helper_irrigation_zone_1_duration
above: 0
mode: restart
icon: mdi:sprinkler
It throws an error massage “Unexpectes value for condition”

The Numeric State Condition in your example contains syntax errors. Posted below is the corrected version. However, I don’t understand why you put the condition at the end of the script. There are no actions after it so it doesn’t matter what is the condition’s result because it’s the end of the script anyway.
alias: script_irrigation_zone_1_start
sequence:
- service: rainbird.start_irrigation
data:
duration: '{{ states(''input_number.helper_irrigation_zone_1_duration'') | int }}'
entity_id: switch.irrigation_zone_1
- condition: numeric_state
entity_id: input_number.helper_irrigation_zone_1_duration
above: 0
mode: restart
icon: mdi:sprinkler
Thank you. Conditions at the beginning of the script and your code: It works! Regards, Eckart
