Panel choice is of course up to you, though we recommend Qolsys over 2GIG.
2GIG still does not publish a confirmed compatible list of Z-wave devices to my knowledge. However, with regard to switches and dimmers, the vast majority of single function Z-wave switches and dimmers should work, given their simplicity.
Qolsys maintains a confirmed compatibility list.
