And that just doesn't work in my application, where I need to be able to dim up the lights slowly from 0.

Umm... There's a kludge you can do to get around this. If you dim the module down to 0% and leave it there then can do the dim up from 0% thing... Does mean you can't really use on/off though as you'll need to do the dim down to 0% each time.

If the lamp module is at 0% already then it will ignore the ON command as it's already on
