3. In Home Assistant, you need to add the notify service to your configuration.yaml file. This should look something like this:

   Copy

   notify:
     - platform: rest
       resource: http: {{ external_api_uri }}v1/external/homeassistant?api_key=<API key>
       method: POST_JSON
       title_param_name: topic
   

4. The api_key parameter should correspond to your bot's key. The stream parameter is not necessarily required; if not given, it will default to the homeassistant channel.

5. And the URL under resource should start with:

   {{ api_url }}/v1/external/homeassistant

6. Finally, you need to configure a trigger for the service by adding an automation entry in the HomeAssistant configuration.yaml file.

   Copy

   automation:
     trigger:
       platform: sun
       event: sunrise
     action:
       - service: notify.notify
         data:
           message: "It will be 30 degrees Celsius out there today!"
           title: "Weather forecast"
   

   The data object takes at least a message property and an optional title parameter which will be the conversation topic and which defaults to homeassistant if not given.
