Remember The Milk

The remember_the_milk integration allows you to create tasks in Remember The Milk (RTM) from Home Assistant. You can use this if you want Home Assistant to send you a task that you should not forget, e.g., water the plants. The integration allows you to have several RTM accounts in parallel.

Setup

The setup consists of two steps: getting an API key and registering your account

Step 1: API key

To be able to use this integration, you need a Remember The Milk account and you need to apply for your own API key. With the API key you will also receive your personal shared secret. Both of them need to be stored in your Home Assistant configuration:

# Example configuration.yaml entry

remember_the_milk:
  - name: your_rtm_account
    api_key: YOUR_API_KEY
    shared_secret: YOUR_SHARED_SECRET

Step 2: Registering your account

After saving the configuration, you need to (re-)start Home Assistant. On the first start you will notice a new “Configuration” panel appearing on the Home Assistant page. After opening the configuration page, follow the link “Remember The Milk login”. This will take you to a login page where you have to log in with your normal Remember The Milk credentials. This will authorize Home Assistant to access your Remember The Milk account.

After that click on the “login completed” button. This will tell Home Assistant that you have completed the login process on the Remember The Milk page and Home Assistant should try to register with this account.

If the registration was successful, the Configuration panel will disappear from your Home Assistant screen and a Remember The Milk panel should appear. This completes the setup process.

In the background Home Assistant downloaded a “token” from the Remember The Milk server which is stored in the remember_the_milk.conf file locally. So you only need to register once. After that the token is used to authenticate with the server.

Creating/updating tasks with service create_task

This integration offers a new service domain remember_the_milk with the services <account>_create_task. You can call this service with the argument name and the optional parameter id to create a new task in your Remember The Milk account. You can call this service from your usual automations.

If you set an id and a task with that id exists already, the existing task is updated, rather than creating a new task. This way you can change the name of the task. If you do not set an id, a new task is created with every call. If you’re using this from an automation, you could use the name of your automation as id or the entity that triggered the task to be created. This way you can later on update or complete this task.

The task creation supports the “smart syntax”, so to create a task with the tag “from_hass” which is due today you can create a task with the name test task created in Home Assistant ^today #from_hass. More info about the smart syntax is available on the Remember The Milk documentation.

Note: At the moment, smart syntax is not supported when updating tasks. All smart syntax commands are ignored during the update and will end up as normal text in the name of the task.

Completing tasks with service complete_task

Complete a tasks that was privously created from Home Assistant. You can not complete tasks that were created outside of Home Assistant.

If you have created your task with an id, calling <account>_complete_task with the parameter id will then complete your task.

Automation example

Here’s an example for an automation that creates a new task whenever sensor.mysensor is on and completes it when the sensor reports off. This way it reminds you to switch it off. By using the entity_id as ID for the task, you can use the same rule also for multiple sensors.

- id: mysensor_on
  trigger:
    platform: state
    entity_id: sensor.mysensor
    to: on
  action:
    - service: remember_the_milk.myaccount_create_task
      data:
        name: "Please switch off {{trigger.entity_id}}"
        id: "{{trigger.entity_id}}"
- id: mysensor_off
  trigger:
    platform: state
    entity_id: sensor.mysensor
    to: off
  action:
    - service: remember_the_milk.myaccount_complete_task
      data:
        id: "{{trigger.entity_id}}"
