I also placed an order today for new wind cups for the weather station. The normal wind sensor has three cups to catch the wind. Mine had been reduced to one cup, through sun damage and birds wanting to tap dance on the arms when it's not rotating, which I'm sure effects the accuracy. So this morning I ordered a replacement wind cup assembly.
We will go from this (one cup),
To this (three cups). Probably will make a difference in the wind reading.
