Would it be possible to receive the signal from one sensor on several stations? (I would like to be able to read the outside temperature from different places in the house).
Hello I can't tell you because I only have the same station once. but I wonder why you only want to use one sensor when there is one sensor with every station!
Conclusion: if you buy 2 stations, you also have 2 transmitters and can do what you actually want:)
Not that I have tested it, but I would say that it is possible. The outdoor sensor is not coupled with the station. The sensor simply transmits its measured values periodically via a 433 MHz radio signal. The sensor does not know whether and from how many stations this signal is received.
However, I cannot guarantee this. To be 100% sure, I would ask the manufacturer.
