1. creating a history sensor

thanks Amit Finkelstein for building this template query

notes:
change באר שבע to your city
scan_interval is set to 2 seconds
time frame is set to 600 (10 minutes)

in configuration.yaml add:

sensor:
  - platform: rest
    name: Silent Red Alert
    resource: https://www.oref.org.il/WarningMessages/History/AlertsHistory.json
    scan_interval: 2
    value_template: >-
      {% if value_json is defined %}
        {% set areas = namespace(list=[]) %}
        {% set priority = namespace(list=[]) %}
        {% for area in value_json %}
          {% if as_timestamp(area.alertDate) > ((now() | as_timestamp) - 600) %}
            {% set new_area = area.data + ' (' + as_datetime(area.alertDate).strftime('%H:%M') + ')' %}
            {% if area.data == 'באר שבע' %}
              {% set priority.list = priority.list + [new_area] %}
            {% else %}
              {% set areas.list = areas.list + [new_area] %}
            {% endif %}
          {% endif %}
        {% endfor %}
        {% set areas.list = (areas.list | sort | list) %}
        {% if (areas.list | length) > 0 or (priority.list | length) > 0 %}
          {{ (priority.list + areas.list) | join(' | ') | truncate(245) }}
        {% else %}
          off
        {% endif %}
      {% else %}
        off
      {% endif %}

2. installing the UI card

HACS manual Installation

• In the HACS Frontend, click the 3 dots in the upper right
• Click 'Add Custom Repository'
• Fill in the repo url https://github.com/silentbil/silent-red and choose 'Lovelace' category.
• Install the custom card (should now appear in the Frontend)

show all cities with alerts (dont pass city parameter)
