| Automation Conditions | Automations can test conditions when invoked. | /getting-started/automation-condition/ |
Conditions are an optional part of an automation rule and can be used to prevent an action from happening when triggered. When a condition does not return true, the automation will stop executing. Conditions look very similar to triggers but are very different. A trigger will look at events happening in the system while a condition only looks at how the system looks right now. A trigger can observe that a switch is being turned on. A condition can only see if a switch is currently on or off.
The available conditions for an automation are the same as for the script syntax so see that page for a full list of available conditions.
Example of using condition:
{% raw %}
automation:
- alias: 'Enciende Despacho'
trigger:
platform: state
entity_id: sensor.mini_despacho
to: 'on'
condition:
condition: or
conditions:
- condition: template
value_template: "{{ state_attr('sun.sun', 'elevation') < 4 }}"
- condition: template
value_template: "{{ states('sensor.sensorluz_7_0') < 10 }}"
action:
- service: scene.turn_on
entity_id: scene.DespiertaDespacho
{% endraw %}
The condition option of an automation, also accepts a single condition template directly. For example:
{% raw %}
automation:
- alias: 'Enciende Despacho'
trigger:
platform: state
entity_id: sensor.mini_despacho
to: 'on'
condition: "{{ state_attr('sun.sun', 'elevation') < 4 }}"
action:
- service: scene.turn_on
entity_id: scene.DespiertaDespacho
{% endraw %}
