The temperature station has relatively large display digits and is, as well as desired by us, armed only with the principal. Unfortunately we had to send the first delivery back because the battery indicator of the external transmitter, even after battery change again, constantly blinking and the outside temperature display often moved without external changes. The replacement was performed without any problems quite quickly. This temperature station works so far been lacking einwandfrei.Leider ind the LED display the point behind the Monatszahl.Damit we can but live. For the price you can not expect too much probably.
