Silly Absolute Pressure

[mcrossley]

Previously, my relative pressure to absolute pressure offset was around 13hPa, since I power cycled the base station, the absolute pressure has jumped up to around 1180hPa, an offset of -165hPa! It remains at this value over subsequent power cycles.

Whilst not a show stopper, it does have one impact - I cannot now change the logging interval via EasyWeather, as EW will not let me submit the setup dialog as the absolute pressure is out of range (max permitted value is 1100 iirc). The absolute pressure is NOT an editable field!

Does anyone any ideas for recalibrating the base station to get the absolute pressure reading back somewhere near normality?

Any hills near you?

Actually, that was a stupid question; I know perfectly well where Wilmslow is as I lived there briefly. Go up into the hills with a laptop and set the interval there. Which is a completely useless suggestion, I know.

I guess that would work if I can find a big enough hill - or a vacuum chamber!

A better weather station is beginning to sound attractive, the Davis is a bit too expensive for the budget controller so any news on WMR100 and WMR200 support? Do you have the protocols and would any volunteer coding/testing help?

I think I have all I need now. Support for it will possibly be in the next-but-one alpha release of Cumulus 2.
