I have installed version 1.07 and restarted home assistant. After that added a new entry and waited for a while. An error is thrown in the add entry dialog but not in the log from HA. I have redownload the previous version 1.06 and noticed that the entries which I tried to add where shown but not initiated.
The earlier created items have been removed, I created a new entry with 1.06 and upgraded to 1.07 . Now it works like a charm.
There seems to be an issue with creating new entries in 1.07.
