Conditions can be used within a script or automation to prevent further execution. When a condition does not return true, the script or automation stops executing. A condition will look at the system at that moment. 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 one 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 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 one 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 one condition statement. Passes if any embedded condition 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 the 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 a highly skewed local time zone.
In those cases 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 are 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 are true.

### Template condition
The template condition tests 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_level')|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](/integrations/workday/).
</div>
### Zone condition
Zone conditions test if an entity is in a certain zone. For zone automation to work, you need to have set up a device tracker platform that supports reporting GPS coordinates. Currently this is limited to the [OwnTracks platform](/integrations/owntracks/) and the [iCloud platform](/integrations/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'
```
