While outside freeze in the 2-digit prevail, shows my new TFA35.1089 wireless weather station Außentemparaturen in 2-digit range on PLUS. The room temperatures give rise to doubts - about 2-3 degrees are always wrong. This really is very annoying, especially design, clarity are very good. Everything at all, I advise against the purchase of this model, especially since these "Macke" seems to occur more often when I read the Rezesionen.
