Fixed Smart Group not being evaluated properly with the listeners. It's fixed. Special thanks to Kaibob2 (Kai) for pointing out this error.
If you are not seeing the update in your panel, and you have 2 sensors, configure one and hit cancel, then go back to the other (any other) sensor. It forces the browser to use the newest code. Browsers cache a ton of information and don't want to change it unless forced.
If you dont have two sensors, make a dummy sensor with one value in it to allow switching and forcing the browser to recache.
