Light switch and receptacle recommendations

I have two of the two of the Switch GE 12722 I use for my outside lights as we have 3 levels and 4 different switches. The two I have installed so far have worked great without any problems for 3-4 months so far and I plan on getting another two for the other two switches I haven’t added yet. I’m not too familiar with the associations as I’m pretty new to openHAB, z-wave, and home automation. But I have individual switch items for controling each switch node and a switch item with a light rule that lets me toggle all of them on/off that works well in openHAB.
