I successfully created a basic application which turns the lights in a certain room on or off. This uses the built-in intent 'turn everything in living room on/off'.
Is it possible to implement custom intents? Let's say I want to implement the intent 'put the lights in party mode', an intent which is not covered by the built-in intents. How can I do this? Can I route Google Smart Home services to Dialogflow intents?
Custom intents as a concept are not supported in the smart home integration for the Google Assistant. However, if you want to have specific feature sets like "party mode", you can create a "SCENE" device in your SYNC response that has the Scene trait. When the user says something like "activate party mode", your cloud integration will get an EXECUTE intent for that scene, which you can handle in any way.
