Reliable Logger - software allows graphical representation

This logger records the measurement data wirelessly (temperature, relative humidity, dew point) and stores it internally. The collected data can via radio (!) Be transferred to a PC.
For me, outside temperature, inside temperature of 5 rooms and the buffer temperature of my heating system to be monitored. The latter in particular is quite handy and works with only a few outages quite well even over 2 floors!
The software (downloadable from TFA Homepage: [...]) allows the graphical representation of the measurement data, so full points!
