Basic Grouping

Hi Every one I am completly new to the z-wave stuff I am used to control4 but decided to play with this. I have some dimmer switches that are controlling lights fine, and a Fabaro Relay swith doing another light in one room, I am trying to configure the s2 on the Fibaro to turn all lights on or off but cannot see how to do this, I know it has something to do with group association but completely lost and cannot find any step by step information on the web. Wonder if someome could help me please ??? ??? ???

Grouping is also something I would like to experiment with. What is your controller? What UI version are you using?

When you say grouping, are you referring to association groups where one device directly controls a group of other devices or do you mean controlling groups of devices such as all lights or sockets. Different methods for each.
Always include details of your controller and firmware when asking questions as answers can change based on this.
