4.3.1. The layer for the lights

As the bulk of the consumers in a home are the lights, we will start with them. Every light is drawn on the floor plan and given a code. When the light is connected to a relay, the code starts with the letter “R”, followed by a figure. The figure designates the output of our integrated home system that the light is connected to. In the drawing below, you can see four lights above the table that have the code “R64”. These four lights can only be switched on and off (relay driven) and they are connected to relay number 64 of the integrated home system. These four lights will therefore always go on and off together. They may be connected to each other in parallel. The wall light on the outside wall will be connected to relay number 2 of the system.

Figure 6: Every light is given a code that immediately gives us a lot of information.

If lights are connected to a dimmer, the code starts with the letter “D”, followed by a figure. Here too, the figure indicates the number of the dimmer that the light is connected to. We will also later use the same figures in the software. This means that when we want to program a certain light, we can easily find it in the software.
