Wind gust and speed

Configuration
1

Hi!
Have a oregon VMR800 wind meter. I have got the wind direction to work, but not speed or gust.
If I look here at the forum the following should be supported in sensor.rfxtrx:

if isinstance(pkt, lowlevel.Wind):
    self.values['Wind direction'] = pkt.direction
    self.values['Wind average speed'] = pkt.average_speed
    self.values['Wind gust'] = pkt.gust
    self.values['Temperature'] = pkt.temperature
    self.values['Chill'] = pkt.chill

Somebody who know if it works? And if so, that can tell me what to do?
