+# Workaround for HomeAssistant 2024.04
+AppDaemon is using the old REST API that until AppDaemon moved on the the websocket API this woraround is needed to get weather forecast data from homeassistant. (https://github.com/AppDaemon/appdaemon/issues/1837)
+
+To get the forecast data in appdaemon, there is a script needed in homeassistant's script.yaml:
+
+```yaml
+call_service_with_response:
+  description: Calls a service and returns its response to AppDaemon
+  fields:
+    call_id:
+      name: Call id
+      default: 1
+      description: An id to uniquely identify the call
+      required: True
+      selector:
+        text:
+    service_name:
+      name: Service name
+      default: domain.some_service
+      description: The service to call
+      required: True
+      selector:
+        text:
+    service_data:
+      name: Service data
+      default: {}
+      description: Data to pass to the service
+      required: True
+      selector:
+        object:
+  sequence:
+    - service: "{{ service_name }}"
+      data: "{{ service_data }}"
+      response_variable: response
+    - event: call_service_with_response.finished # event name cannot be templated unfortunately
+      event_data:
+        call_id: "{{ call_id }}"
+        response: "{{ response }}"
