The weather station is with me (since mid-August) in use. It is connected to a wireless outdoor sensor, which measures the temerature in the garden house (about 10m from the temperature radio sensor). This function is the main function of the weather station for my needs. Until now, (in September) even a failure of the data transmission. However, I could not determine the cause, the battery capacity from both the sensor and the weather station it was not. After restarting the data transfer, it went back - without failure until now. You can complain about the operating instructions and use the weather station. The text of the manual is so tiny that it takes almost a magnifying glass as a reading aid. In addition, it is m. E. confusing and insufficiently detailed. There is an "alert" function for alarm and an "alert" function for the temperature warning. Whether there is a difference in sound quality among different warnings, the manual can not be inferred. Operation with the buttons on the rear panel is m. E. particularly in the alarm / alert settings also complicated and fiddly. The alarm / alert features give me still more puzzled: First, I had a minimum temperature "alert" is set. After a few days, an alarm / alert was triggered without the minimum temperature has been reached (Was it another alarm? But I did not set a time interrupt). After that I also have the temperature "alert" issued. Two days later came again briefly several times an alarm. However, I could not tell why. Since so far no more. I want when the alarm / alert settings not rule out that this is with me somehow acted to operator error, I want to express thus in any case that the operation in conjunction with the user manual is not easy and m. E. is unique or complicated. At the other functions and displays I have nothing to complain about. The display is easy to read.
