LB120 only works with on/off

[marcurdy]

I was able to add the LB120 to Echo only after setting a hint. I've tried many 1.2.*.0 values, and all act the same. It allows for on and off, but it won't accept a brightness percentage. I tried setting the brightness in the Amazon app and through voice. Setting this manually in the ISY console works. Maybe a different hint is needed?
