|
Conditions can be used within a script or automation to prevent further execution. A condition will look at the system right now. For example a condition can test if a switch is currently turned on or off.
|
|
|
|
Unlike a trigger, which is always `or`, conditions are `and` by default - all conditions have to be true.
|
|
|
|
### AND condition
|
|
|
|
Test multiple conditions in 1 condition statement. Passes if all embedded conditions are valid.
|
|
|
|
```yaml
|
|
condition:
|
|
condition: and
|
|
conditions:
|
|
- condition: state
|
|
entity_id: 'device_tracker.paulus'
|
|
state: 'home'
|
|
- condition: numeric_state
|
|
entity_id: 'sensor.temperature'
|
|
below: 20
|
|
```
|
|
|
|
If you do not want to combine AND and OR conditions, you can also just list them sequentially.
|
|
|
|
The following configuration works the same as the one listed above:
|
|
|
|
```yaml
|
|
condition:
|
|
- condition: state
|
|
entity_id: 'device_tracker.paulus'
|
|
state: 'home'
|
|
- condition: numeric_state
|
|
entity_id: 'sensor.temperature'
|
|
below: 20
|
|
```
|
|
|
|
Currently you need to format your conditions like this to be able to edit them using the [automations editor](/docs/automation/editor/).
|
|
|
|
### OR condition
|
|
|
|
Test multiple conditions in 1 condition statement. Passes if any embedded condition is valid.
|
|
|
|
```yaml
|
|
condition:
|
|
condition: or
|
|
conditions:
|
|
- condition: state
|
|
entity_id: 'device_tracker.paulus'
|
|
state: 'home'
|
|
- condition: numeric_state
|
|
entity_id: 'sensor.temperature'
|
|
below: 20
|
|
```
|
|
|
|
### MIXED AND and OR conditions
|
|
|
|
Test multiple AND and OR conditions in 1 condition statement. Passes if any embedded conditions is valid.
|
|
This allows you to mix several AND and OR conditions together.
|
|
|
|
```yaml
|
|
condition:
|
|
condition: and
|
|
conditions:
|
|
- condition: state
|
|
entity_id: 'device_tracker.paulus'
|
|
state: 'home'
|
|
- condition: or
|
|
conditions:
|
|
- condition: state
|
|
entity_id: sensor.weather_precip
|
|
state: 'rain'
|
|
- condition: numeric_state
|
|
entity_id: 'sensor.temperature'
|
|
below: 20
|
|
```
|
|
|
|
### Numeric state condition
|
|
|
|
This type of condition attempts to parse the state of specified entity as a number and triggers if the value matches the thresholds.
|
|
|
|
If both `below` and `above` are specified, both tests have to pass.
|
|
|
|
You can optionally use a `value_template` to process the value of the state before testing it.
|
|
|
|
```yaml
|
|
condition:
|
|
condition: numeric_state
|
|
entity_id: sensor.temperature
|
|
above: 17
|
|
below: 25
|
|
# If your sensor value needs to be adjusted
|
|
value_template: {% raw %}{{ float(state.state) + 2 }}{% endraw %}
|
|
```
|
|
|
|
### State condition
|
|
|
|
Tests if an entity is a specified state.
|
|
|
|
```yaml
|
|
condition:
|
|
condition: state
|
|
entity_id: device_tracker.paulus
|
|
state: 'not_home'
|
|
# optional: trigger only if state was this for last X time.
|
|
for:
|
|
hours: 1
|
|
minutes: 10
|
|
seconds: 5
|
|
```
|
|
|
|
### Sun condition
|
|
|
|
#### Sun state condition
|
|
|
|
The sun state can be used to test if the sun has set or risen.
|
|
|
|
```yaml
|
|
condition:
|
|
condition: state # 'day' condition: from sunrise until sunset
|
|
entity_id: sun.sun
|
|
state: 'above_horizon'
|
|
```
|
|
|
|
```yaml
|
|
condition:
|
|
condition: state # from sunset until sunrise
|
|
entity_id: sun.sun
|
|
state: 'below_horizon'
|
|
```
|
|
|
|
#### Sun elevation condition
|
|
|
|
The sun elevation can be used to test if the sun has set or risen, it is dusk, it is night etc. when a trigger occurs.
|
|
For an in depth explanation of sun elevation see [sun elevation trigger][sun_elevation_trigger].
|
|
|
|
[sun_elevation_trigger]: /docs/automation/trigger/#sun-elevation-trigger
|
|
|
|
```yaml
|
|
condition:
|
|
condition: and # 'twilight' condition: dusk and dawn, in typical locations
|
|
conditions:
|
|
- condition: template
|
|
value_template: {% raw %}'{{ state_attr("sun.sun", "elevation") < 0 }}'{% endraw %}
|
|
- condition: template
|
|
value_template: {% raw %}'{{ state_attr("sun.sun", "elevation") > -6 }}'{% endraw %}
|
|
```
|
|
|
|
```yaml
|
|
condition:
|
|
condition: template # 'night' condition: from dusk to dawn, in typical locations
|
|
value_template: {% raw %}'{{ state_attr("sun.sun", "elevation") < -6 }}'{% endraw %}
|
|
```
|
|
|
|
#### Sunset/sunrise condition
|
|
|
|
The sun condition can also test if the sun has already set or risen when a trigger occurs. The `before` and `after` keys can only be set to `sunset` or `sunrise`. They have a corresponding optional offset value (`before_offset`, `after_offset`) that can be added, similar to the [sun trigger][sun_trigger].
|
|
|
|
[sun_trigger]: /docs/automation/trigger/#sun-trigger
|
|
|
|
<div class='note warning'>
|
|
The sunset/sunrise conditions do not work in locations inside the polar circles, and also not in locations with highly skewed local time zone.
|
|
|
|
It is advised to use conditions evaluating the solar elevation instead of the before/after sunset/sunrise conditions.
|
|
</div>
|
|
|
|
```yaml
|
|
condition:
|
|
condition: sun
|
|
after: sunset
|
|
# Optional offset value - in this case it must from -1 hours relative to sunset, or after
|
|
after_offset: "-01:00:00"
|
|
```
|
|
|
|
```yaml
|
|
condition:
|
|
condition: or # 'when dark' condition: either after sunset or before sunrise - equivalent to a state condition on `sun.sun` of `below_horizon`
|
|
conditions:
|
|
- condition: sun
|
|
after: sunset
|
|
- condition: sun
|
|
before: sunrise
|
|
```
|
|
|
|
```yaml
|
|
condition:
|
|
condition: and # 'when light' condition: before sunset and after sunrise - equivalent to a state condition on `sun.sun` of `above_horizon`
|
|
conditions:
|
|
- condition: sun
|
|
before: sunset
|
|
- condition: sun
|
|
after: sunrise
|
|
```
|
|
|
|
A visual timeline is provided below showing an example of when these conditions will be true. In this chart, sunrise is at 6:00, and sunset is at 18:00 (6:00 PM). The green areas of the chart indicate when the specified conditions will be true.
|
|

|
|
|
|
### Template condition
|
|
|
|
The template condition will test if the [given template][template] renders a value equal to true. This is achieved by having the template result in a true boolean expression or by having the template render 'true'.
|
|
|
|
```yaml
|
|
condition:
|
|
condition: template
|
|
value_template: "{% raw %}{{ (state_attr('device_tracker.iphone', 'battery')|int) > 50 }}{% endraw %}"
|
|
```
|
|
|
|
Within an automation, template conditions also have access to the `trigger` variable as [described here][automation-templating].
|
|
|
|
[template]: /topics/templating/
|
|
[automation-templating]: /getting-started/automation-templating/
|
|
|
|
### Time condition
|
|
|
|
The time condition can test if it is after a specified time, before a specified time or if it is a certain day of the week
|
|
|
|
```yaml
|
|
condition:
|
|
condition: time
|
|
# At least one of the following is required.
|
|
after: '15:00:00'
|
|
before: '02:00:00'
|
|
weekday:
|
|
- mon
|
|
- wed
|
|
- fri
|
|
```
|
|
|
|
Valid values for `weekday` are `mon`, `tue`, `wed`, `thu`, `fri`, `sat`, `sun`.
|
|
Time condition windows can span across the midnight threshold. In the example above, the condition window is from 3pm to 2am.
|
|
|
|
<div class='note tip'>
|
|
|
|
A better weekday condition could be by using the [Workday Binary Sensor](/components/binary_sensor.workday/).
|
|
|
|
</div>
|
|
|
|
### Zone condition
|
|
|
|
Zone conditions test if an entity is in a certain zone. For zone automation to work, you need to have setup a device tracker platform that supports reporting GPS coordinates. Currently this is limited to the [OwnTracks platform](/components/device_tracker.owntracks/) and the [iCloud platform](/components/device_tracker.icloud/).
|
|
|
|
```yaml
|
|
condition:
|
|
condition: zone
|
|
entity_id: device_tracker.paulus
|
|
zone: zone.home
|
|
```
|
|
|
|
### Examples
|
|
|
|
```yaml
|
|
condition:
|
|
- condition: numeric_state
|
|
entity_id: sun.sun
|
|
value_template: '{{ state.attributes.elevation }}'
|
|
below: 1
|
|
- condition: state
|
|
entity_id: light.living_room
|
|
state: 'off'
|
|
- condition: time
|
|
before: '23:00:00'
|
|
after: '14:00:00'
|
|
- condition: state
|
|
entity_id: script.light_turned_off_5min
|
|
state: 'off'
|
|
```
