To-do item removed

The To-do item removed trigger is useful when you want Home Assistant to react after an item disappears from a list. You can use it to notify someone, refresh a related routine, or keep another system in sync with your to-do list.

Using this trigger from the user interface

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

To use this trigger in an automation:

1. Go to Settings > Automations & scenes.
2. Open an existing automation, or select Create automation > Create new automation.
3. In the When section, select Add trigger.
4. Select what you want to monitor. Under By target (see Targets), pick the to-do list you want to watch. You can also select an area, floor, device, entity, or label if that target resolves to one or more to-do lists.
5. From the triggers shown for that target, select To-do item removed.
6. Select Save.

Options in the UI

This trigger has no additional options beyond the target.

Using this trigger 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 trigger as todo.item_removed. A basic example looks like this:

trigger: todo.item_removed
target:
  entity_id: todo.shopping_list

This fires every time an item is removed from todo.shopping_list.

Options in YAML

This trigger has no additional YAML options beyond the target.

Targets of the trigger

This trigger requires a target. The target is the object that Home Assistant will watch. You can select 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 as a target, and Home Assistant will watch every matching todo entity behind that target.

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

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

Good to know

• This trigger fires after Home Assistant removes one or more items from the targeted to-do list.
• Changes to unavailable or unknown do not count as items being removed.
• Trigger data includes the to-do list entity_id and the affected item_ids, which can be useful in a more advanced automation.
