Here is a link to my weather station which was installed in June 2008.
The software is Cumulus by Steve Loft and the hardware, a Watson 3081 wireless array.
The original 8681 unit performed reasonably well until late September 2012 when a seized bearing and a botched repair caused total failure of the anemometer.
The pressure sensor failed in mid December 2015 and is still u/s while the solar/UV systems were very unreliable until adding a small amount of filtering to the sensor (plastic film). Since this addition the light levels have fallen within the predicted curve.
