I have to win the aforementioned device for about 4 weeks in operation (single-family) to monitor in different rooms temperature / humidity and possibly from the measured values. Insights. I have the basic machine with 2 radio transmitters combined (no. 30.3180) and can thus measure the values in 3 rooms at the same time. That was with me for. B. living room (with KlimaLogg per basic unit) respectively, cellar and bedrooms with a radio probe. This works just fine! The measurement intervals can vary from 1 minute up to 6 hours, so a lot of leeway. The transmission of measured values Temperature and rel. Humidity is easily achieved via a (supplied) USB flash drive after the KlimaLog one has installed Pro software on the PC. It opens the Proigramm, a table opens, and the data transfer is started by pressing the USB button on the base unit. Afterwards you can of this table from the measurement data export to any folder on your PC. There you now find them in an Excel spreadsheet in addition to the dew point for each pair of values! I think that's very helpful, because it can be estimated well, if one has to reckon with moisture problems in the room in question! In summary, I want to emphasize that I am very happy with this unit (+ radio transmitter). I would buy it again and it can absolutely recommend.
