I set-up a motion light app to set a lutron dimmer to certain level, but got the following errors from log. It looks like there are two overloaded setLevel() exposed from a lutron dimmer, and the app cannot figure out which method to invoke.
Can you do a screen shot of the rule?
Hmm, somehow I cannot reproduce it anymore... It now works fine 
Here is the screen shot.
That log of setting dimmer level to null is suspicious. Now the log shows it sets the level to 75. Oh, would it be because I tested in the 'day' mode, which won't trigger the turn on in theory, so a null is passed in which confuses the method selection?
Let me remove the evening mode and see if I can reproduce it.
I think you found the issue. Glad I could help.
