This week I'm going to look at using Z-Wave Association to easily implement a motion activated light.
The aim of this is to have a light that turns on when motion is detected, stays on for a preset time and then turns off - and for this to only work when the ambient light is below a defined level.
One of the easiest and most efficient ways to do this is by using Z-Wave Association.
So what's Association?
In most Z-Wave applications we configure them so that the central controller handles all commands. So for this example; the motion detector would send a signal to the controller and as a second step the controller would send a command to the light control (a Fibaro dimmer in this case). However, this adds unnecessary steps which can make this communication take too long.
Associating the motion detector and dimmer, enables the motion detector to send signals directly to the dimmer without involving the controller. This saves time, reduces the complexity of the communication and the amount of airtime taken. It also allows sensors to be used in networks without a static controller.
Take a look at the Application Note and Video to see how I got on implementing this application.
See you next week.
Mark.
