Example

node-panasonic-viera has been designed to be used quite straight forward and without introducing ackward language constructs. The following example should give a brief introduction on how to use node-panasonic-viera in your own applications:

const {VieraKeys, Viera} = require('node-panasonic-viera');

const viera = new Viera();

// CONNECT
viera.connect('192.168.178.140', 'JkasiKDjwuKasW==', 'J19DKDfju283jKFzlaO9za==')
  // 1. power on TV
  .then(() => {
    return viera.sendKey(VieraKeys.power);
  })
  // 2. set volume to 20
  .then(() => {
    return viera.setVolume(20);
  })
  // 3. get volume
  .then(() => {
    return viera.getVolume();
  })
  // 4. output volume level
  .then((volume) => {
    console.log(volume);
  })
  // catch errors
  .catch((error) => {
    console.log(error);
  });
