Timer is idle

The Timer is idle condition passes when the timer is not running. Use it when an automation should continue only if the timer has not started yet, has finished, or was cancelled.

Labs

Requires the Purpose-specific triggers and conditions Labs preview feature. Enable it at Settings > System > Labs.

Using this condition from the user interface

If you prefer building automations visually, Home Assistant walks you through this condition step by step. You pick what to check, tweak a few options, and save. No YAML knowledge required.

To use this condition in an automation:

  1. Go to Settings > Automations & scenes.
  2. Open an existing automation, or select Create automation > Create new automation.
  3. In the And if section, select Add condition.
  4. Select what you want to check. Under By target (see Targets), pick the timer you want to check. You can also select an area, a floor, a device, or a label.
  5. From the conditions shown for that target, select Timer is idle.
  6. Under Condition passes if (see Behavior), pick Any or All.
  7. Under For at least, set how long the timer must stay idle before the condition passes. Leave the default to check the current state only.
  8. Select Save.

Options in the UI

Condition passes if

When multiple timers are targeted, controls how results combine. Pick Any to pass if at least one targeted timer is idle, or All to pass only if every targeted timer is idle.

For at least

How long the timer must remain idle before the condition passes. Defaults to 00:00:00.

Using this condition in YAML

If you work directly in YAML, or you want to know exactly what Home Assistant does under the hood, this section has the technical reference. It lists the field names you use in YAML, their types, and which ones are required.

In YAML, refer to this condition as timer.is_idle. A basic example looks like this:

ConditionConditions are an optional part of an automation that will prevent an action from firing if they are not met. [Learn more]
condition: timer.is_idle
target:
  entity_id: timer.guest_room

This passes when timer.guest_room is idle.

Options in YAML

YAML sometimes provides additional options for more complex use cases that are not available through the UI.

behavior string

When multiple timers are targeted, controls how results combine. Accepts all or any.

for string

How long the timer must remain idle before the condition passes. Accepts a duration string in HH:MM:SS format.

Targets of the condition

This condition requires a target. The target is the object that Home Assistant will check. You can point the condition at a single entityAn entity represents a sensor, actor, or function in Home Assistant. Entities are used to monitor physical properties or to control other entities. An entity is usually part of a device or a service. [Learn more], a device, an area, a floor, or a label, and Home Assistant will evaluate every matching timer entity behind that target.

  • Entity: one specific timer entity, such as timer.living_room.
  • Device: every timer entity that belongs to a device.
  • Area: every timer entity in a room or area.
  • Floor: every timer entity on a floor.
  • Label: every timer entity that shares a label.

You can also select different target types in one condition. For example, you can add a specific entity and an area as targets in the same condition to check both of them at once.

Behavior with multiple targets

When you target more than one entity (or select an area, floor, or label that contains several), the Condition passes if option controls how the results combine:

  • Any (default): the condition passes if at least one of the targeted entities matches. For example, if you check three smoke sensors and only one of them detects smoke, the condition still passes. This is useful for questions like “is there smoke anywhere in the house?”
  • All: the condition passes only when every targeted entity matches. For example, if you check the same three smoke sensors, the condition passes only once all three report cleared. This is useful for “is the entire house safe now?” checks, so your automation does not send an all-clear while one room still has a reading.

Good to know

  • A timer is idle when it has not started yet, has finished, or was cancelled.
  • Timers that are unavailable or unknown are skipped for Any and cause All to fail.

Try it yourself

Ready to test this? Go to Settings > Automations & scenes, open an automation, and add this condition. Trigger the automation with and without the condition met, and watch whether it continues or stops.

Tip

You don’t need to edit YAML to use these examples. Copy a YAML snippet from this page, open the automation editor in Home Assistant, and press Ctrl+V (or Cmd+V on Mac). Home Assistant automatically converts the pasted YAML into the visual editor format, whether it’s a full automation, a single trigger, a condition, or an action.

Automation: start the guest room light only if the timer is idle

If the guest room timer is not already running, you can safely start a new timed lighting routine.

  • Trigger: Time: 19:00
  • Condition: Timer is idle
    • Target: Guest room timer
  • Condition passes if: Any
  • Action: Turn on light

Automation: arm the alarm only if the departure timer is idle

Use this condition to avoid arming the alarm while a departure timer is still running.

  • Trigger: Person leaves home zone
  • Condition: Timer is idle
    • Target: Departure timer
  • Condition passes if: Any
  • Action: Arm away

Tip

AI assistants like ChatGPT or Claude can also explain conditions or suggest the right one when you describe what you want in plain language.
