The node provide two outputs. The first output emits a `msg.payload` of <i>1</i> or <i>0</i> every minute
|
|
|
|
|
depending if day-time (1) or night-time (0).

|
|
|
|
|
|
|
|
The second output emits only on the transition between night to day (<i>-> 1</i>) or day to night (<i>-> 0</i>).

|
|
It also sets the `msg.topic` to <i>sun</i> and `msg.moon` to the fraction of the moon currently visible
|
|
|
|
|
(a value between 0 for no moon and 1 for full moon).</p>
