Connecting to players

Our API lets you connect to your Yoto devices, perform specific actions on them, and receive updates on their state.

This happens via the MQTT protocol. Here’s how it works:

Step 1: Connect to the MQTT broker

The MQTT broker is available at wss://aqrphjqbp3u2z-ats.iot.eu-west-2.amazonaws.com. You’ll need to authenticate using a JWT token.

First, set up the authorizer name:

Here’s how to connect:

const clientId = `DASH${deviceId}`;

mqttClient = mqtt.connect(MQTT_URL, {
  keepalive: 300,
  port: 443,
  protocol: "wss",
  username: `${deviceId}?x-amz-customauthorizer-name=PublicJWTAuthorizer`,
  password: accessToken,
  reconnectPeriod: 0,
  clientId,
  ALPNProtocols: ["x-amzn-mqtt-ca"],
});

Step 2: Get your devices

First, fetch your devices from our API:

const deviceResponse = await fetch(
  "https://api.yotoplay.com/device-v2/devices/mine",
  {
    headers: {
      Authorization: `Bearer ${accessToken}`,
    },
  }
);
const { devices } = await deviceResponse.json();

// select a device to connect to
const deviceId = devices[0].deviceId;

Step 3: Subscribe to device topics

Once connected, subscribe to these topics for your device:

const topics = [
  `device/${deviceId}/events`,
  `device/${deviceId}/status`,
  `device/${deviceId}/response`,
];

Step 4: Send commands

You can now send commands to your device. For example, to set the volume:

const volumeTopic = `device/${deviceId}/command/volume/set`;
const volumePayload = { volume: 3 };
mqttClient.publish(volumeTopic, JSON.stringify(volumePayload));

Step 5: Handle messages

The client will receive messages on the subscribed topics:

mqttClient.on("message", (topic, message) => {
  const [base, device, messageType] = topic.split("/");

  if (device === deviceId) {
    const payload = JSON.parse(message.toString());

    if (messageType === "events") {
      // Handle device events
    } else if (messageType === "status") {
      // Handle status updates
    } else if (messageType === "response") {
      // Handle command responses
    }
  }
});

Don’t forget to check if the device you’re trying to connect to is online before attempting to connect.
