This HomeMatic device replaces with me the more expensive air humidity sensor. Heating valves or window monitoring I do not control so currently. The data is forwarded to the program-controlled home automation system. So it is no problem that the timing can not be programmed directly dependent on the humidity, I. In this case actually need (dehumidifier in the basement) Only the measured values seem to me somewhat inaccurate, for the intended purpose but adequate.
