Weather warnings

Warnings of the DWD and NINA from Home Assistant on one tile, in the spirit of the Lovelace nina-dwd-card.

The tile (1 x 1 and up) shows the strongest warning in force: its icon (thunderstorm, wind, rain, snow, ice, fog, heat ...) in a circle of its level's colour, its short name ("Sturmböen") and until when it lasts, and "+2" when there are more. The tile itself takes the level's colour lightly: yellow for a weather warning, orange for notable weather, red for severe weather, purple for extreme weather. NINA's severities count the same (Minor, Moderate, Severe, Extreme). Without a warning it shows a quiet shield and "No warnings", or the DWD's advance warning, muted.

A tap opens a card with every warning, the strongest first and the advance warning last: a bar in its level's colour, its icon and headline, when it is in force and where it comes from, and its text in as many lines as fit.

Set up

1. Have the DWD Weather Warnings integration for your region (sensors ..._current_warning_level and ..._advance_warning_level) and, if you like, the NINA integration (binary sensors binary_sensor.warning_<place>_1 and so on).
2. In Tessera, open Plugins, Add with a link, and paste the link of this repository. Add the plugin to a screen.
3. In the plugin's details on the screen's Plugins tab, under When building, choose DWD current warning level, DWD advance warning level and up to two NINA warning slots; leave out what you do not use. Save and build.
4. In Layout, place the Weather warnings tile.

Good to know

• The screen reads the sensors and their attributes itself; a change of the chosen entities builds the screen again.
• The DWD's first three warnings, its first advance warning and two NINA slots are shown.
• Without a time the tile names the source ("DWD", "NINA"). A DWD level whose warnings have no details (yet) shows as "Warning level 1".

NINA with headline and times

Newer Home Assistant versions give NINA's binary sensors only the attribute id; the headline, severity, text and times come from the action nina.get_details. Without them the tile shows "NINA warning" in its colour. A template binary sensor brings them back as attributes; choose it instead of the NINA sensor in the plugin's details. Put it in configuration.yaml (or a file of your template: folder), with your sensor in place of binary_sensor.warning_place_1, once per slot:

template:
  - triggers:
      - trigger: state
        entity_id: binary_sensor.warning_place_1
      - trigger: homeassistant
        event: start
      - trigger: time_pattern
        minutes: "/10"

        state: "{{ is_state('binary_sensor.warning_place_1', 'on') }}"
        attributes:
          headline: "{{ ((nina | default({}, true)).get('binary_sensor.warning_place_1') or {}).get('headline', '') }}"
          severity: "{{ ((nina | default({}, true)).get('binary_sensor.warning_place_1') or {}).get('severity', '') }}"

          expires: "{{ ((nina | default({}, true)).get('binary_sensor.warning_place_1') or {}).get('expires', '') }}"
