Welcome to the Google Home Developer Center, the new destination for learning how to develop smart home actions. Note: You'll continue building actions in the Actions console.

Request to send a local device command over UDP datagram. Commands are sent to the device using DeviceManager.send.

Example UDP command:

const payload = new Uint8Array([0x00, 0xFF, 0x00, 0xFF]);

const command = new DataFlow.UdpRequestData();
command.requestId = request.requestId;
command.deviceId = 'device-id';
command.port = 5555;
command.data = Buffer.from(payload).toString('hex');
command.expectedResponsePackets = 1;

Handle the response

If the command succeeds, DeviceManager.send returns a UdpResponseData result. For commands with UdpRequestData.expectedResponsePackets set, the result contains a UdpResponse.

const command = new DataFlow.UdpRequestData();
command.expectedResponsePackets = 1;
...

localHomeApp.getDeviceManager()
 .send(command)
 .then((result: DataFlow.CommandSuccess) => {
   const udpResult = result as DataFlow.UdpResponseData;
   const packets = udpResult.udpResponse.responsePackets;
 })
 .catch((err: IntentFlow.HandlerError) => {
   // Handle command error
 });
