Start automation when any Todo-List item is completed

Configuration
1

I want to play applause on my smart speaker whenever I completed an item on my todo list. :tada: You somehow need to motivate yourself, right? :upside_down_face:

How can I trigger such an automation?

Thank you for your assistance!

I donā€™t use this myself, but you have a lot of information on how to do it in the documentation To-do list - Home Assistant

Well, I did read the documentation before posting here. I could not find the answer to my question in it.

Have you looked at the entities that the integration provides and what status they give?

5

Every Todo list has the number of open tasks as its state. I need to trigger an automation whenever this number decreases by one. But how can I do this?

6

You could use a counter decrease trigger in your automation :slight_smile: You might need to create a counter helper (I use this to trigger my secondary robo vacuum when my primary has cleaned three times).

7

This works in your robo vacuum use case since in your example you trigger an automation when the counter reaches a certain number. But this could not be used to trigger an automation upon any decrease independent of the current value. Am I wrong?

Try looking into template sensors, I believe that should solve it. Iā€™m not an expert on template sensors so someone else could probably help you out if needed.

The basic way is to use a template condition:

trigger:
  - platform: state
    entity_id: todo.example
    not_from:
      - unavailable
    not_to:
      - unavailable
condition:
  - alias: Check if the new state is less than the old state
    condition: template
    value_template: "{{ trigger.to_state.state | int < trigger.from_state.state | int }}"
action:
  # Your Notification Actions

Just be aware that the example above will also fire if someone deletes an item that has the status ā€œneeds_actionā€. The other way to do it is with an Event trigger, but the way the ToDo-related events work leaves weird edge cases that would also falsely trigger your automationā€¦ so I donā€™t know if itā€™s worth the complication.

Thank you, this works! :+1: I didnā€™t know about template conditions until now.
