I think the unit looks good. (Read, for example, to short the clock or the temperature) The 3 distinguishable union colors ('backlight' of the display), etc. and in particular the possibility to activate it short with almost any remote control or motion sensor is certainly not found in any weather station.
Operation with batteries (4xMignon) or power supply possible. But now to the essential:
Already on the 1st day after unpacking then but a little strange - the temperature of the outdoor sensor (placed next to the device) deviated from about 2 degrees of reading on the main unit. However, the external sensor was not important and never really with me in action - that is why I unfortunately only now (2 years later) found: not only the temperature is displayed incorrectly, the humidity is totally wrong. Have inzw measured it with 2 other Geäten:. Humidity is partly incredible 18 percentage points next to.. The temperature 'only' 2-5 degrees wrong. Absolutely out of the question!
On the website of Technoline then the contact just did not work (e-mail, I also tried - I have to say it never received). Have it now tried again by email - And indeed - an answer to my rather long description of the problem (one sentence): ". Exchange not possible after the warranty"
Conclusion: since hygrometer and thermometer completely useless, I can only strongly advise against any of the purchase. A pity, with correct data, the device would be right up my alley.
(In the example, 'Weather forecast' I will not go into here, is in many weather stations rather a gimmick've also promised not much of it.)
