One issue with hobbyist weather stations is that they aren't particularly useful for use for assimilating into numerical weather models. The pressure is useful as it is relatively hard to get that wrong unless mislabelling sea-level pressure as station pressure.

Other variables can be significantly in error due to the siting of the station: under a tree, not aspirated, in the wake of a building, on a rooftop, etc.

I think wind it particularly hard to get right. However, any station contributing to the CWOP can be looked up on 'weather.gladstonefamily.net' for really nice quality control stats against other local stations. For reference, here is one I randomly picked in the Nashville area that is passing quality control for pressure and temperature, but failing the wind QC:

I would think there is still value there, at a sufficient scale.
