Usage: ${usage}

Log deCONZ websocket notifications to stdout.
Parameters:
  ${b('-h')}          Print this help and exit.
  ${b('-V')}          Print version and exit.
  ${b('-n')}          Do not retry when websocket connection is closed.
  ${b('-r')}          Do not parse events, output raw event data.
  ${b('-s')}          Do not output timestamps (useful when running as service).
  ${b('-H')} ${u('hostname')}[${b(':')}${u('port')}]
              Connect to ${u('hostname')}${b(':')}${u('port')} instead of the default ${b('localhost:443')}.`
