Temperature Trigger

Configuration
1

Hi,

I would like to create at an automation with a trigger of 32 degrees for my local city, to where it will send me an alert every 30 minutes until the temp goes above 32 degrees.

I think I can figure out a way to do the latter but how can I create a trigger that pulls the local temp for my area and set it to 32 degrees?

Thank you!

template:
  trigger:
    - platform: state
      entity_id: weather.home
      attribute: temperature
  sensor:
    - name: Current Temperature
      state: "{{ state_attr('weather.home','temperature')|float(0) }}"
      unit_of_measurement: "°F"
      state_class: measurement
      device_class: temperature
      unique_id: my-temp-415f1b49-886b-4455-a579-e28deb46335a

Something like that.

You should be aware, that to create a notification that repeats every X minutes, instead of an automation, you should look at the alerts integration. It exists for this very use case -

You would set a binary sensor so your template sensor would now be:

template:
  trigger:
    - platform: state
      entity_id: weather.home
      attribute: temperature
  sensor:
    - name: Current Temperature
      state: "{{ state_attr('weather.home','temperature')|float(0) }}"
      unit_of_measurement: "°F"
      state_class: measurement
      device_class: temperature
      unique_id: my-temp-415f1b49-886b-4455-a579-e28deb46335a

  binary_sensor:
    - name: Low Temperature
      state: "{{ states('sensor.current_temperature')|float(0) <= 32 }}"
      device_class: cold
      unique_id: cold-alert-75053340-9aa6-45ba-b67c-a439d3c84f3f

Then your alert can reference the binary sensor.

That can be simplified considerably:

template:
  - binary_sensor:
      - name: Low Temperature
        state: "{{ state_attr('weather.home','temperature')|float(0) <= 32 }}"
        device_class: cold
        unique_id: cold-alert-75053340-9aa6-45ba-b67c-a439d3c84f3f

There’s no need for a triggered template. The template above will update when the attribute changes.

Thanks so much to both of you!

I am still learning so two questions.

  1. Where do I insert this code? Do I create a new automation and then past it into the automation’s YAML?
  2. Which of these fields do I need to customize, if any? For example, I am assuming the unique_id will need edited? Where do I input what city/state I am in so that it polls my local temp?

Thank you!
