Although the current Night Mode already greatly lowers the brightness and just shows a clock, I would appreciate an option to just have the Tidbyt show a blank screen instead.
So a toggle for night mode to turn the clock on and off. I like my room really dark sorry 
We have debated offering this as a built-in feature, with one concern being that it’s not clear if the Tidbyt is “off” or unplugged, broken, etc.
However, there is a community app called “Blackout” that you can install and schedule for whenever you like. All it does is completely blank out the screen.
