I wanted a weather station that can display two, better yet three transmitters me at least. So, this works just fine. I combine these TFA 30.3032.10 with the corresponding station with the TFA 35.1045.IT - and their stations. The Result: the stations from TFA 30.3032.10 has two sensors - a sensor measures directly on / in the transmitter, the second sensor has an approximately 1.20 m long cable! and hanging in the pool! In addition, I use as a third receiving value of the transmitter TFA 35.1045.IT - of course I can not read the Hygrometerwerte here, but on the second station in the living room I read all our 3 stations from values. Works phenomenal! Oh, subject waterproof - NO, the transmitters are not! only the sensor is tight, the transmitter itself is not! My solution would cling film - sparking so far without problems.
From me a good buy recommendation in connection with the pool temperature display!
