Bathroom lights

This recipe describes the lifecycle of the main lights in the bathroom.

These lights should be:

• off when the bathroom is empty,
• at 60% when the bathroom is occupied between 8:00 am and sunset,
• at 30% when the bathroom is occupied during the evening (sunset to dusk),
• at 12% when the bathroom is occupied from dusk to 8:00 am,
• at 1% when the bathroom is occupied between 22:00 and 7:30 am, when the adjoining bedroom is in "bed mode", to avoid waking up the person in bed (or waking yourself up with too bright lights in the middle of the night).

Requirements

• Bathroom mmWave Presence - Occupancy sensor for the bathroom.
• Bathroom light - The main light in the bathroom, can fade from 0 - 100%.
• Mirror light - The light surrounding the mirror, on/off only.
• Bedroom ceiling light - The main light in the bedroom.

Scene: Vacant

The first scene turns off the lights when the occupancy sensor goes clear for 2 seconds (a small timeout to catch false positives):

Scenes: Daytime, Evening, Nighttime

The next three scenes cover the daytime, evening, and nighttime light settings. Daytime covers 8:00 am to sunset, the Evening time of day covers sunset to dusk, and the Nighttime scene doesn't need to specify a time range because Daytime and Evening will match any times that aren't between dusk and 8:00 am.

There is no need to specify an Occupancy condition on these scenes because they come after the Vacant scene. If the Vacant scene's Occupancy is clear condition doesn't match, then that means the bathroom is occupied.

Scene: Person present, in bed mode

The only way to reach the bathroom is via the adjoining bedroom. If somebody enters the bedroom then the lights turn on. When that person climbs into bed, they turn the lights off. That means that we can assume that the bedroom is in "bed mode" if the main bedroom light is off.

In this case, we fade the bathroom light to 1% and leave the mirror light off, as it would be too bright.

Should the person who has entered the bathroom want to make the bathroom light brighter, or to turn on the mirror light, they can do so manually. There is no trigger that will reset the lights until the bathroom becomes vacant again.

Note: we've manually moved the Vacant scene above the Person present, in bed mode scene because its Occupancy condition gates all of the other scenes.

Lifecycle

Person enters bathroom at sunset	Evening	Lights fade to 30%
Person enters bathroom at 23:00, bedroom Ceiling light is on	Nighttime	Lights fade to 12%
Person enters bathroom at 23:00, bedroom Ceiling light is off	Person present, in bed mode	Bathroom light fades to 1%
