I have a Meteobridge sending data from a Davis Vantage Pro 2 to the the UK Met Office WoW database. The Davis weather receiver displays wind in m/s and the live data displays both m/s and mph but the data received by WoW is in knots. WoW doesn't do any unit conversion so it is not possible to change the displayed units on the website.

I presume that data is sent to WoW via their API with a message structure rather like the following WoW example.

http://wow.metoffice.gov.uk/automaticreading?siteid=123456&siteAuthenticationKey=654321&dateutc=2011-02-02+10%3A32%3A55&winddir=230&windspeedmph=12&windgustmph=12&windgustdir=25&humidity=90&dewptf=68.2&tempf=70&rainin=0&dailyrainin=5&baromin=29.1&soiltempf=25&soilmoisture=25&visibility=25&softwaretype=weathersoftware1.0

For the above example the encoding for knots would be windspeedkts and windgustkts rather than windspeedmph and windgustmph. Is Meteobridge sending the wind speed in knots?

What is your WOW alternate units set to?

The wind speed is configured in WoW for m/s. However WoW have confirmed that if data is received in a different unit then it will default to that unit. I have requested that WoW check the data upload and report the data string but I have not had any reply as yet. It would be helpful to know exactly what Meteobridge is sending.
