Trigger your lights as you normally do (ON/OFF) and the brightness will be automatically set based on a Sleep Mode toggle. Optionally, you can instantly override the brightness in an “emergency” using dedicated Override helper toggles.
I wanted an easy way to have lights automatically dim when the kids are off to bed, but also to be able to instantly turn any light on with maximum brightness as needed - especially for those late-night wake-ups, when someone is sick, or during sibling showdowns! 
I know there are a bunch of other blueprints that handle Sleep Mode, but I wanted something simple with a manual override and without the extra stuff I don’t need like motion, sun and lux etc…
I hope this is useful and can save someone some time. If it is useful I might start releasing some of the other things I have built up over the years (after cleaning up the code first of course!).
