Automation conditions

A condition checks whether something is true right now. For example, a condition can check whether a door is closed, or whether someone is home. When a trigger starts the automation, Home Assistant checks the conditions. If they are met, the automation runs its actions. If not, the automation stops.

You add conditions in the And if section of the automation editor, with Add condition. Conditions are optional. Without conditions, the automation runs its actions whenever a trigger starts it.

Built-in and integration conditions

• Conditions that come with an integration are named after what they check. Integration conditions include Light is on and Sun is up.
• Conditions that are built into Home Assistant aren’t tied to an integration. You can use them with entities from any integration. Built-in conditions include State, Numeric state, Time, and Template.

For the conditions that come with an integration, refer to the list of available conditions. For the built-in conditions, and for writing conditions in YAML, refer to Conditions.

Conditions check the current state

A condition checks the state at the moment the automation runs.

This is why:

• A condition doesn’t start the automation when it becomes true. To start the automation when something becomes true, use a trigger.
• If the state changes after the check, the condition isn’t checked again. The automation continues or stops based on that one check.

For examples, refer to Conditions check the current state.

Conditions and building blocks

If an automation has several conditions, all of them must be met. To combine conditions in a different way, select Add condition, and then select Blocks:

• Or: met if at least one of the conditions inside is met.
• Not: met if none of the conditions inside are met.
• And: met if all conditions inside are met. Use it inside an Or or Not block.

You can also check a condition between the actions under Then do:

• To stop the remaining actions when a condition isn’t met, use the Condition building block.
• To do different things depending on a condition, use If-then or Choose.

Testing conditions

You can check whether a condition is met right now, without running the automation. For the steps, refer to Testing a condition.
