I wanted a weather station without battery ("old") and especially to control the humidity and I am very satisfied. The accuracy (factory calibrated according to the manual) is between -1 and +1 ° C compared to other measuring devices.
For the humidity, it is not the value measured by my dehumidifier (10% difference) but I had a doubt on the reliability of the latter.
Small advantage, it may be arranged horizontally (we know rotate each probe) and re-adjust as needed.
