AppDaemon

Tips

• To find event names :
  1. Go to https://your-homeassistant-address/developer-tools/event (Developer tools > Events)
  2. Write "*" under "Listen to events"
  3. Click in "Start listening"
  4. Fire the event (for instance turning a button on)

How to create an AppDaemon application and run it when clicking a button

Requirements:

• Button card (install with HACS)
• AppDaemon (add-on)

Steps

1. Create a helper with "Input button" type.
2. Add a Button card to a dashboard:

     - show_name: true
         show_icon: false
         type: custom:button-card
         name: '#0000FF'
         entity: input_button.sc_button_blue
         show_state: false
         color_type: card
         icon: ''
         styles:
           card:
             - background: rgb(0, 0, 255)
             - color: white
         tap_action:
           action: perform-action
           perform_action: input_button.press
           target:
             entity_id: input_button.sc_button_blue

3. Create the AppDaemon application :
   1. Define application in configuration file (usually in addon_configs/a0d7b954_appdaemon/apps/apps.yaml) :

      app_name:
          module: module_name
          class: YourApp
          button_id: input_button.sc_button_blue

   2. Add the Python code into addon_configs/a0d7b954_appdaemon/apps/module_name (the module name is defined in AppDaemon configuration YAML):

   3. import appdaemon.plugins.hass.hassapi as hass
      
      
      class ScApp(hass.Hass):
          """AppDaemon application to interact with SC RPI."""
      
          def initialize(self) -> None:
              """Initialize configurations."""
              entity_id = self.args["button_id"]
              state = self.get_state(entity_id, attribute="all")
      
              if state is not None:
                  actual_state = state["state"]
                  attributes = state["attributes"]
      
                  self.log(f"State: {actual_state}")
                  self.log(f"Attributes: {attributes}")
      
                  self.listen_event(
                      self.button_pressed_handler,
                      "state_changed",
                      entity_id=entity_id,
                  )
              else: 
                  self.log(f"get_state returned None for {entity_id}")
      
          def button_pressed_handler(
              self, event_name: str, data: dict[str, Any], **_kwargs: Any
          ) -> None:
              """Button press event handler."""
              self.log(f"Button event received event {event_name} and data {data}")
