The wave is a discontinued unit, because it sucked up to much battery juice. I would just use it with the axlink connection, and yes you do need a processor. You can get an old Axcent 3 or Axcent 2 from ebay, or purchase a new one from a dealer and get a newer model like an NI 2000 or NI 3000, depends on how many devices you want to control. You can find a dealer and the specs on

Good Luck.
