Ordered the logger, along with 3 radio transmitters, to "watch" my heating on. The radio transmitter can be linked easily. Operation is simple. Install and use the software easily fold, synchronization of data via radio as well. As others wrote: Too bad that you have to start Synchro at logger. Otherwise, the software is simple, but adequate. I export the data to Excel and CSV've programmed macros for the graphical representation of temperature patterns. Note: the outdoor stations with 433MHz will NOT work with this logger, although he described as "often bought together" is displayed.
