Passing to do list to esphome

[styphonthal]

So my goal is to pass a local to do list from home assistant to esphome so I can display it. I’ve tried using a template as a sensor but I’ve failed passing the info. My plan was to create four items/sensors based on the first four on my Todo list.

Nice task you got yourself here.

Haven’t done such a thing myself, but I’d go at it this way:

• Setup a trigger-based template sensor
  This sensor needs to have an action, where you call the service todo.get_items. If you call that service, it will give you back a response variable. This variable can than be used in the state of that template sensor. In this case, I’d use it to populate the items from the todo list as attributes for that sensor.
• In ESPHome you can use a “Home Assistant Text Sensor” and get the attributes from it, aka. the items on the todo list.
• Display it

As I said, this is of the top of my head, not tested!

Hope this helps to get you started.

I tried this without success:

template:
  - trigger:
      - platform: state
        entity_id: todo.google_keep_things_to_do_today
      - platform: event
        event_type: event_template_reloaded
    action:
      - service: todo.get_items
        data:
          status: needs_action
        target:
          entity_id: todo.google_keep_things_to_do_today
        response_variable: todo_list_list
    sensor:
      - name: to do listed
        unique_id: todo_list_list
        # Add the missing "state" key and define the desired state
        state: >  # Use Jinja2 templating for dynamic state
            {{ todo_list_list[todo.google_keep_things_to_do_today]['items'] | map(attribute='summary') | list | count > 0 }}
'''

Please format your code properly, we can’t see, if there are errors in it, without proper formatting.

See here:

How to format your code in forum posts

Spaces at the beginning of the line are critical in yaml, and people trying to help you may want to copy your code so that they can try it out themselves, so please format it correctly when you are posting. Use the preformatted text tool (</> in the edit post toolbar). If it is not immediately visible, it will be in the cogwheel menu. [Code_format] Alternatively you can use three backticks (the key is on the far left, 2nd row on en keyboards) on their own line above and below the code. That i…

Thanks!

Added correct format

Thanks!

Something like that, but I’d safe the items as attributes. State has the disadvantage, that it is limited to 255 characters.

Like so:

template:
  - trigger:
      - platform: state
        entity_id: todo.google_keep_things_to_do_today
    action:
      - service: todo.get_items
        data:
          status: needs_action
        target:
          entity_id: todo.google_keep_things_to_do_today
        response_variable: todo_list_list
    sensor:
      - name: to_do_listed
        unique_id: todo_list_list
        state: >-
# this is the number of items/entries on the to-do list
            {{ states('todo.google_keep_things_to_do_today') }} 
        attributes:
          items: >-
            {% for item in todo_list_list['todo.google_keep_things_to_do_today']['items'] %}
            {{ item }}
            {% endfor %}

This saves each of the items (all of them!) as one list entry in the attributes from the template sensor.

You can get these attributes in ESPHome in the text sensor

text_sensor:
  - platform: homeassistant
    id: todo_list
    entity_id: sensor.to_do_listed
    attribute: items

I have been trying to assign each to do list item as a separate attribute, but I am failling. Any ideas on how to fix it?

- trigger:
      - platform: state
        entity_id: todo.google_keep_things_to_do_today
      - platform: event
        event_type: event_template_reloaded
    action:
      - service: todo.get_items
        data:
          status: needs_action
        target:
          entity_id: todo.google_keep_things_to_do_today
        response_variable: todo_list_list
    sensor:
      - name: to_do_listed
        unique_id: todo_listed
        state: "{{ now().isoformat() }}"
        attributes:, 
          {% for i in range(todo_list_list['todo.google_keep_things_to_do_today']['items'] | length) %}
            {{ i }}_summary: "{{ todo_list_list['todo.google_keep_things_to_do_today']['items'][i].summary }}"
          {% endfor %}

Any ideas with this? I am able to pass all items on the list to one attribute but not separate them.

[paddy0174 (Patrick)]

I’d say that’s not possible, at least I don’t know a way. You can’t template the key (name) of an attribute, just the value.

But the question is, why? You can loop through the attribute in ESPHome.
