I live in Germany and I just replaced my X-Core with an OpenSprinkler. In general I am very happy, that I now can control my irrigation system on-line. I would also like to use the wunderground weather control. Unfortunately the Zimmerman method doesn’t fit to my area. Does anyone know the perfect adjustment settings which I could use in Germany?
In firmware 2.1.5, we added weather adjustment options which lets you modify the scale of each factor in the Zimmerman method. This should allow you to tweak the adjustment for your environment.
