Support Heinrich-Hertz-Schule, Hamburg, Vertretungsplan in Home Assistant

Note:

• This integration only makes sense to you, if your kid is attending the Heinrich-Hertz-Schule in Hamburg, Germany.
• You will need a user name and a password to access the data. Please ask your Elternvertreter.

Setup

Installation:

• Go to HACS -> Integrations
• Click the three dots on the top right and select Custom Repositories
• Enter https://github.com/kongo09/hass-hhs-vertretungsplan as repository, select the category Integration and click Add
• A new custom integration shows up for installation (HHS Vertretungsplan) - install it
• Restart Home Assistant

Configuration:

• Go to Configuration -> Integrations
• Click Add Integration
• Search for HHS Vertretungsplan and select it
• Specify the tutor group (Klasse) your kid is attending
• Add your user name and password
• If you have more than one kid, you can repeat the process and get one sensor per kid

Usage:

The integration provides a binary_sensor for the tutor group your kid is attending. The sensor has a list of all current classes that will be substituted or not take place according to the current planning of the school.

Entities:

Provided you did the setup for tutor group ´7f´ you get the following sensor:

Entity ID	Type	Description
binary_sensor.hhs_7f	Binary Sensor	Is on, if there is Vertretung today, for 7f. See attributes for details

Attributes:

The sensor has two attributes:

Name	Content
status	Date and time of when the data was updated by the school (not the sensor)
vertretung	List of classes that are cancelled or substituted

The list has the following attributes for each class that is cancelled or substituted:

List attribute	Content
datum	The date when the substitution takes place
klasse	The tutor group affected. This will be the tutor group you configured the sensor for, or alle
stunde	Timing of the class affected
vertreter	The stand-in teacher taking care of the kids
fach	The class affected
raum	Which room is affected. This is where the kids where originally supposed to be
text	Some informational text from the school, e.g. if kids stay in their own classroom
nach	Some further information
day	The school day of the week - that's easier to read for the kids, but somewhat redundant to datum

Display:

There is no dedicated Lovelace card for this, and showing lists is not very common in Home Assistant. I suggest the following configuration to display the sensor:

type: custom:stack-in-card
mode: vertical
cards:
  - type: entities
    entities:
      - type: custom:template-entity-row
        entity: binary_sensor.hhs_7f
        color: |-
          {% if is_state(config.entity, 'Vertretung') %}
            #FDD835
          {% endif %}
        secondary: >-
          Status von  {{ as_timestamp(state_attr(config.entity, 'last_update'))
          | timestamp_custom('%-H:%M Uhr am %A') }}
  - type: conditional
    conditions:
      - entity: binary_sensor.hhs_7f
        state: Vertretung
    card:
      type: custom:flex-table-card
      entities:
        include: binary_sensor.hhs_7f
      columns:
        - data: vertretung
          modify: >-
            var days = ['Montag', 'Dienstag', 'Mittwoch', 'Donnerstag',
            'Freitag', 'Samstag', 'Sonntag'];

            var d = new Date(x.datum).getDay();

            days[d-1]
          name: Tag
        - data: vertretung
          modify: x.stunde
          name: Stunde
        - data: vertretung
          modify: x.fach
          name: Fach
        - data: vertretung
          modify: x.vertreter
          name: Vertr.
        - data: vertretung
          modify: x.raum
          name: Raum
        - data: vertretung
          modify: '[x.text, x.nach].filter(Boolean).join('', '')'
          name: Info

This results in the following card:

Note, that this requires two custom frontend cards: custom:stack-in-card, custom:template-entity-row and custom:flex-table-card which need to be installed via HACS as well. They are part of the HACS index and can be found with the built-in search.
