important VP2 temperature offset info

[4wd]

This started to become an issue a few years ago with the result that if you change your T/H sensor now you might not be informed (I wasn't) by vendor.
Basically older VP2 stations will need a significant -0.5C offset if you get the current sensor.
There are probably a few of the older ones floating about so care needed.

Luckily less than three months data affected here before correction made, it's not realistic to backdate the correction though.

Yup didn't apply to me as the vp2 board died in the intervening years so I had the newer board in place. Unless the sensor is nist calibrated you always need to adjust the temperature anyway when replacing sensors after allowing time for the sensor to get the correct temperature.
