Houston, I think we have a problem!

I can't beleive the humidity is still 100% outside, but it's been stuck on it
since yesterday evening. Any ideas/solutions?

I had the opposite problem a few weeks ago. Over a period of a few days the RH
on my Vantage Pro 2 gradually drifted down to less than 5%. I solved the
problem by replacing the temp/RH sensor with one of the new 'enhanced' sensors
which are supposedly more accurate. It has all been working fine since then.

I'm not really sure what caused the problem but it developed shortly after a
spell of wet weather with very strong winds. It's possible that water getting
to the sensor was the problem but I'm only guessing.
