Home Assistant Automation for freezing warnings

[nap@sh.itjust.works]

Hey Folks. I was wondering how to warn me before my whole water stuff outside freezes and bursts cause I forget to check the weather. The Solutions I found while searching the web did not click with me so here is what I came up with:

alias: Freezing Warning
description: ''
triggers:
  - trigger: time
    at: '07:00:00'
conditions: []
actions:
  - variables:
      message: Your massage to go out and close those Vales and empty the hoses
      mtittle: Freezing Alarm!
      minTemp: 2
  - action: weather.get_forecasts
    metadata: {}
    target:
      device_id: ChangeMe
    data:
      type: daily
    response_variable: daily
  - if:
      - condition: template
        value_template: |-
          {% set ns = namespace(freezing=false) %}
          {% for day in daily['weather.forecast_home'].forecast %}
            {% if day.templow < minTemp %}
              {% set ns.freezing = true %}
            {% endif %}
          {% endfor %}
          {{ ns.freezing }}
    then:
      - action: notify.send_message
        metadata: {}
        target:
          device_id: ChangeMe
        data:
          title: '{{ mtittle }}'
          message: '{{ message }}'
mode: single

Just a simple Automation. No editing template.yaml files. Could add a condition with a helper var like "I closed the vales etc" and don't remind me every day. Guess I'll do that...
Be sure to change the ID of you location and ID of you mobile device for the message.

have fun,
bye
