[OBSOLETE] Iris Smart Plug (3210-L) Zigbee Plug with Z-wave Repeater

I want to add here that per the thread I link below, this custom device handler is no longer needed to add Iris Smart Plug 3210-L to Smartthings Hub. In fact, you need to delete this custom device handler in order for Smartthings to discover the Iris Smart Plug as Smartthings hub now supports this Zigbee device natively.
