Now the warranty has expired and a few months later the weather station was completely up the ghost, before even the first battery set was empty (at least 21 months after the purchase, which is a power for the batteries). When I opened the Weather Station (in the hope of finding a mistake) I was amazed at how cheap and simple part is cobbled together: On the display board are quite simply a DCF module, a Empfangsmpodul and a simple logic to display values soldered. All apparently standard components.
Conclusion: A weather station which you have to change more often than the batteries is not worth the money!
By the way - as a substitute I now have worried Plus 35.1109 me www.Amazon.com/gp/product/B0066L4GT8 TFA Dostmann wireless weather station Neo. Since then fell the same as the wireless sensor from (and forwarded only temperature and no humidity). The replacement unit seems, however, at least so far to do his job, and the clock works.
Tip: anyone who gets a weather station, should make prior to daily use the trouble to let outdoor sensor and the main station overnight directly adjacent to each other and then to compare the values. For I have learned that depending on the model, the measured values of both units obviously can vary considerably (the record was 10%). The waiting time is actually absolutely necessary, since this alone can touch the batteries (or the humidity of the air we breathe) is already registered by the sensitive sensors.
