Setting up Growstuff plantings as Home Assistant Sensors [WIP]

[CloCkWeRX]

Home Assistant is a home automation platform that supports a range of sensors and triggers.

My use case is to display the progress of my plantings in the home assistant dashboard.

Home assistant supports a generic rest integration:
https://www.home-assistant.io/integrations/rest/

  - platform: rest
    name: Growstuff Plantings
    resource: https://www.growstuff.org/members/clockwerx/plantings.json
    value_template: '{{ value_json.crop_name }}'
    json_attributes:
      - crop_name
      - finish_predicted_at
      - percentage_grown
      - thumbnail_url
      - active
      - slug
  - platform: template
    sensors:
       crop_percentage:
        friendly_name_template: '{{ states.sensor.growstuff_plantings.attributes["crop_name"] }} Percentage'
        value_template: '{{ states.sensor.growstuff_plantings.attributes["percentage_grown"] }}'
        entity_picture_template: '{{ states.sensor.growstuff_plantings.attributes["thumbnail_url"] }}'
        attribute_templates:
          finish_predicted_at: '{{ states.sensor.growstuff_plantings.attributes["finish_predicted_at"] }}'
          slug: 'https://www.growstuff.org/plantings/{{ states.sensor.growstuff_plantings.attributes["slug"] }}'

Note: I tried using the API, but got errors

curl -X GET "https://www.growstuff.org/api/v1/plantings?filter%5Bowner%5D=clockwerx" -H "accept: application/vnd.api+json"

This will get your first crop and show the attributes:

Remaining tasks

• Multiple crops without repeating sensors - rewrite as custom component?

Oh, nice!

Turned into a repo: https://github.com/Growstuff/homeassistant-growstuff

Would be neat to link it to irrigation somehow

One of my main issues is scheduling. Going to work a bit on just making the above custom component easy to setup (config flow).

Roadmap for this; if I don't get distracted by shiny things:

• Config flow
• Look at what write capabilities we could have, to push "Watered" events in
• Long term statistics if applicable?
