Dining Room¶

This recipe controls the Table Light above the Dining Room table. It is only turned on when somebody is seated at the table, and the brightness varies by time of day. The light is turned off more quickly when the projector in the adjoining Lounge is in use.

Requirements¶

Table Light - the light above the Dining Room table.
Zone Table - occupancy sensor which detects when somebody is seated at the table.
Cine Logitech - the remote which tells us when the projector is in use.

Scene: Vacant¶

The first scene turns off the Table Light once the Zone Table has been vacant for 5 minutes. We wait 5 minutes so that the light isn't flashing on and off every time somebody moves in and out of the Zone Table area:

Vacant.

Scenes: Daytime, Evening, Nighttime¶

We add a scene for Daytime (which fades the Table Light to 40%), Evening (35%), and Nighttime (30%).

Daytime, Evening, and Nighttime.

The Nighttime condition doesn't need a Time of day condition because it comes after the Daytime and Evening scenes.

Scene: Block until table zone detected¶

We didn't include an Occupancy condition in the Daytime, Evening, and Nighttime scenes because they come after the Vacant scene, so we know that the table is either occupied or has only been vacant for less than 5 minutes.

However, if we restart Home Assistant it will clear the last detected time on the presence sensor which would mean that the Vacant scene wouldn't match and the Table Light would turn on for up to 5 minutes.

For completeness we can prevent that occurring by adding a blocking clause:

Block until table zone detected.

Scene: Vacant and Projector in use¶

Finally, we want the Table Light to turn off more quickly when the projector is in use, so we add a scene with the highest priority which turns the light off after 1 minute of vacancy:

Vacant and projector in use.
