Callback registered with the App via App.onReachableDevices to discover additional devices connected to a proxy or hub.
When a device that is discovered by the IdentifyHandler is a proxy which enables indirect access to other devices (identified by the isProxy flag in the IdentifyResponse), the local home platform sends a
REACHABLE_DEVICES
intent to discover the additional devices visible to the proxy.To learn more about how the platform verifies reachable devices, see the developer guide.
const devicesHandler = (request: IntentFlow.ReachableDevicesRequest): IntentFlow.ReachableDevicesResponse => { // Reference to the local proxy device const proxyDevice = request.inputs[0].payload.device.proxyDevice; // Query local proxy device for additional visible ids // ... const reachableDevices = [ // Each verificationId must match one of the otherDeviceIds // in the SYNC response { verificationId: "local-device-id-1" }, { verificationId: "local-device-id-2" }, ]; // Return a response const response: IntentFlow.ReachableDevicesResponse = { intent: Intents.REACHABLE_DEVICES, requestId: request.requestId, payload: { devices: reachableDevices, }, }; return response; };
