Hey Guys i am using the Android APP with local Server, sofar every thing works fine.
I have disconnected my wlan and tried with Remote Access (myopenhab.org etc), i see my sitemap and all my items, but i am not able to change status of switch etc. If i switch something off nothing happens.

cache cleaned und restartet
Thanks

What are your config settings for the openHAB cloud on MainUI?
Did you select Notifications&Remote Access?
yes it is set to:Notifications&Remote Access
i found it 
URL was set to: http://myopenhab.org/
i have changed it to: https://myopenhab.org and now its working
I have set it up that way and do have remote access (note that publishing any item is NOT necessary! )
Does your setup (for openHAB or the whole local net) use any security specials?
