Thank you very much! I have other two questions:
– Rain Sensor: I see that arduino version have a port to connect wired rain sensor. I’ve read in a post that a similar port will be also available on raspberry pi from version 1.3. Are there some limitations about wire lenght?
– Temperature/Humidity sensor: I see that the arduino version can use sensor dht22 to get temperature/humidity informations. Is it possibile to use the same sensor on rapsberry pi version? In this way you can have irrigation and weather station in one device.
