Just to help you save some work: I have found the Z-wave repeater portion of these to not be very good. I have 10 of these plugs, most are 3210-L and a few 3210-L2. My humble suggestion is to just not include the Z-wave part, especially if you have other mains-powered Z-wave devices that act as repeaters.
If you choose to ignore that advice, you should at least consider using this driver for the Z-wave repeater: [RELEASE] Iris SmartPlug Z-Wave Repeater (3210-L + others)
