var harmony = require('@harmonyhub/client');

harmony('192.168.1.200')
  .then(function(harmonyClient) {
    harmonyClient.isOff()
      .then(function(off) {
        if(off) {
          console.log('Currently off. Turning TV on.');

          harmonyClient.getActivities()
            .then(function(activities) {
              activities.some(function(activity) {
                if(activity.label === 'Watch TV') {
                  var id = activity.id
                  harmonyClient.startActivity(id)
                  harmonyClient.end()
                  return true
                }
                return false
              })
            });
        } else {
          console.log('Currently on. Turning TV off');
          harmonyClient.turnOff();
          harmonyClient.end();
        }
      })
  });

This example connects to a Harmony hub available on the IP 192.168.1.200. As soon as the the connection is established, isOff() checks if the equipment is turned off. If off, the activity with the name Watch TV is started. If on, all devices are turned off.
