Lucky me - I'll be blessed. At least the temperature has never been so off that I thought it was wrong. It probably has something to do with where you put the station. The humidity should also be pretty good. But I don't have any comparative values. However, the question is what you can expect from a station for this price. If you buy (too) cheap, you buy twice. If you want a really good station, you will have to spend more money on it.

I think it depends on the location, 2m above ground, shade? (if it is exposed to the sun, it shows higher values for the outside temperature).
For me it is accurate enough ;-)
