Did you take the Auriol Transmitter with you?
Because all the information reads a bit confusing for me.

As I got it, you have to set your WeatherDuino back to factory reset. Then the WeatherDuino binds the first signal from the first radio signal it gets. So if it is not from your Auriol Transmitter unit is can be anything and thus it is decoded wrong.

I would suggest to reset the WeatherDuino and Power it up first time in the cellar with the Auriol Transmitter beneath it. This has be done each time the battery is pulled out from the Auriol Transmitter.
So the WeatherDuino knows which data belongs to your TX and processes it.
You can also write me in German if something is still unclear.

PS. Are you a tram driver since the WeatherDuino is sitting in the very front.

Hello engolling,
I did not take the sensors with me. At home I had the problem that the Duino has received data from a temperature sensor, although my sensors were de-energized. Therefore, I have taken him to work to see if he finds a temperature sensor in the wild. This is not the case and now I know that at home there must be at least one sensor that interferes with mine. Thanks for the tip with the cellar. I was not aware that the Duino remembers the data of my sensors and connects with them again when he had no power. As I visit my parents tomorrow, I will take everything with me and set up there. Yes, I'm a tram driver in Leipzig.
