Light and Dark
One of the important things HCA does is to control lighting. It is often useful to know if your home
is light or dark to determine if lights should be turned on and at what level.
The question “is it light or dark” can be answered by sunrise and sunset time but there are other
options.
There is the same dialog for Dark and well as Light.
While this dialog has many options the general idea is that you determine light from three possible
sources.
By Time
By the setting of a flag – determined by programs you have created
By s selection of motion sensors which contain a light sensor
At the top of the dialog is a dropdown where you pick what sources determine light or dark and
haw those sources interact. In the above example, it will be considered Light at the local sunrise or
when all of the selected motion sensors report that it is light.
In later chapters of this user guide you will see two places where you can make use of this
information: In the auto off settings of rooms and devices and in programs where you can test the
flag “_Light” or “_Dark”. HCA keeps those flags up to date during the day as it reevaluates the
light and dark settings specified here.
Hint: Because there are separate criterion for Light and Dark it is possible for both to be true or
both to be false.
