const shellies = require('shellies')

shellies.on('discover', device => {
  // a new device has been discovered
  console.log('Discovered device with ID', device.id, 'and type', device.type)

  device.on('change', (prop, newValue, oldValue) => {
    // a property on the device has changed
    console.log(prop, 'changed from', oldValue, 'to', newValue)
  })

  device.on('offline', () => {
    // the device went offline
