Give 5 stars because the thermo-hygrometer does what it promises

Have hygrometer bought because I have problems with mold growth in the rented apartment and the cause would get to the bottom. In addition I wanted to take my time dependence of the humidity and make inferences, how long do I have to ventilate or how long the Badventilator must run in order to exchange the air bathroom sufficient.

Have it taken together with another compatible thermo-hygro transmitter of TFA in use. The hygrometer is now hanging in the bedroom and the transmitter is in the bathroom. As both initially lay side by side, the deviation of the measured humidity usually was 0-2%, in the temperature measurement, it was not even 1 degree deviation. The outdoor transmitter was by a few seconds carrier in the measurement. So overall, much better than I would have thought.

The measured values ​​are updated on the devices approximately every 5-10 seconds, the shortest time interval when saving the measured values ​​for subsequent readout is to my knowledge one minute.

It is true what was in some reviews to read that you have to press on the PC to transfer the data a button on the hygrometer. For this, the Software ("KlimaLogg Pro" Subtracting from the TFA Dostmann website) running and the USB radio stick be plugged into the PC. The Übetragung of data a few days before then can take about 1-2 minutes. Excluding run the Software then, every minute is mitgeplottet. The once transmitted data are then retained when you open the software.

The fact that the software a bit rudimentary comes, is fair enough. However quite sufficient for the intended purpose of me. Better rudimentary and it works as vice versa.
A bit of getting used to is the function to "Out-zoom", this one has to draw a zoom on the vertical axis of the graph field. Also you have to watch that you have selected the correct time in the settings window to the right of the diagram.

So as it is written in power with me, what it promises. Despite borderline rudimentary software. Have also nothing like can be found in the price range.
