Room Lighting is a comprehensive app built into Hubitat targeted towards automating switches, dimmers, bulbs, and window shades in a room (or really any group of devices you select, whether one or several or in the same room or not).
Complex lighting automations
Use custom events from any device to turn on or off lights and similar devices
Optionally add restrictions that control if or when devices turn on or off or modify behavior based on hub mode or time of day
As a way to group devices or create scenes - a more powerful alternative to the Groups and Scenes app
In many cases, a “Turn Off” in Room Lighting might actually be turning off the lights — though you are not limited to this possibility. You can choose any settings for Activation and Turn Off settings, which determine what happens for each half of the automation.
The Activation Settings table determines what happens in response to an Activation, and Turn Off options allow either the defaults of turning off the lights or an option to restore the devices to their previous state (before Activation) or to predetermined settings.
Room Lighting can also gradually fade lights to off over a predetermined period of time, allowing a sort of “warning” before turning off the lights (or going to predetermined settings for Turn Off).
