RainMachine has multiple weather services which have global coverage. We even tested it for Antarctica (where the freeze protect feature would definitely be useful). By Default NOAA is enabled and has Global coverage. RainMachine can also fetch weather data from Metno (global, but with better resolution for EU countries).
Currently RainMachine only supports only English language, but as interest outside the US continues to grow, we will make more languages available for users. For electrical compatibility, RainMachine has a standard US transformer rated for 120V 60Hz outlets. Before using in Europe or another region, make sure you have the correct adapter before plugging the unit in to avoid damaging the RainMachine.
