The Lowe’s Iris model 3210-L is an extremely unusual device in that it includes both a zigbee radio and a zwave radio. The zigbee radio is used to control the on/off for the pocket socket and is also is also a zigbee repeater. Z wave radio does not control the pocket socket itself, and is only used as a zwave repeater. It is been very popular in the community as a dual purpose device.
BTW, if you look it up on the official zwave alliance products site, it won’t show up under on/off devices, which makes sense since the zwave radio doesn’t turn the module on and off. But it is listed under “network devices” with the single purpose repeaters from other brands.
