A Hub using websockets for IoT devices to communicate through, both sensor-devices and clients. It expects sensors to pass readings through the 'sensor:data' event using the following scheme (with potential custom changes if necessary):

  {
    id: 'some individual identifier for a device',
    type: 'the class of the device, e.g. sensortag',
    sensor: 'the type of the sensor, e.g irTemperature',
    data: someObjectWithSensorData
  }

The hub will redistribute the payload of 'sensor:data' events to all connected devices as 'client:display' events. It is up to connected clients to interpret and use the passed data. We propose the above payload structure of sensor reading events to facilitate multiple clients receiving and interpreting data from sensor devices.
