I am contemplating to purchase the Iro in the US during my next trip and use it in Germany. I have downloaded the Android App and simulated a set-up. My question is how can I ensure that German weather data are used? How does the system know that the zip-code I am entering during the set-up is a German zip-code and not a US one? I want to make sure that I am not buying the Iro and then are unable to use it in Germany because I cannot set it up. Are there already any users in Germany?I fully understood that I will have to source my own power adaptor. This is not a problem as I have done this before for other devices bought in the US.
