Well, there’s two ways that it can be done, and you set up how it is done under Setup and then Day / Night. Here you can set whether dawn and dusk are calculated, or if a sensor is to be used. X10 motion sensors have the ability to send an on code on the next unit code when it gets dark, and an off code when it gets light. For instance, if your motion sensor is set up for A1, then it will send an on signal for code A2 when it gets dark out, and when it gets light again, it will send the off signal for A2. If you choose to let Home Domination calculate the dawn and dusk time for you, you will need to enter your approximate latitude, longitude, and time zone. This
