Instructions

  1. Find the following nodes in the palette on the left side of the Node-RED:

  • Light Scheduler

  • inject

  • vertex action

  • vertex cluster

 

  1. Drag the nodes and drop them onto the workspace.

  2. Go to the Light Scheduler node, in the section Globals, select the icon with a pen.

3. Set the name, longitude and latitude of your investment/building.

4. Mark Output, On Payload and Off Payload as shown below.

This option ignores the schedule, leave this section blank.

5. Conditions of the Dusk/Dawn part should be set as shown in the screenshot below. Use Only when dark option and, in the Threshold field, -18o - Astronomical dawn / Night.

6. Go to the inject node and mark messages and the repeat interval as shown below.

7. Go to the vertex action node and choose direct value mode with action set brightness (scale percent).

8. Link all the nodes and select the Deploy button.
