slajgaj, Sorry I am not planning to support UI5. I do not have a system to test with UI5. I do plan on implementing a LAN only checkbox in the setting which will allow only direct access via LAN (you'll have to enter the IP of the controller as well in the settings). I'm not 100% sure, but I think the luup requests I use to manage everything didn't change from UI5 to UI7. I think (again, not sure, but think this is the case. Someone else feel free to chime in and let me know if my assumptions are correct) that the main difference and why it doesn't currently work with UI5 is the login verification stuff. If that's taken out though (direct access) then it should work. If that is the case once I get the LAN only mode in place you can use that mode to access the controller, but you will only be able to do so while connected to your wifi.
I tried the app again today and it worked. I'm not sure if yesterday vera was having issues, or my home internet connection, but it worked. Others who are having issues would you mind testing it again and let me know if it works? If nothing appears try clicking "save" in the settings menu on your phone. This will resubmit the verification stuff, and re-cache your lights. Thanks for any help.
