I hoste the settings website on my dropbox account. And dropbox stop the host service… 🙁
But i updated the watchapp last week. This should fixed the “Check you internet connection” Error.
If youre still have problems, write my an email over the pebble app 🙂
@skyynet i use my OpenSprinkler to drive Gardena valves too. With the OpenSprinkler i upgraded my system from 3 valves to 9. The Gardena Vales are very easy, you can drive them with 24V AC or DC. 😉
