Disconnect

If the user unlinks your smart home Action from Google Assistant, your fulfillment receives an action.devices.DISCONNECT intent. This intent indicates that Assistant will not send any more intents for this user, and your cloud service should stop calling Google Home Graph APIs (Request Sync and Report State) for their devices.
