Z-Wave is built on definable blocks, which include, among others, transmission and application layers. It is a stand-alone solution that can run an entire home of devices and subsystems. We also recognise that Z-Wave needs to be compatible with these other standards. As an application layer, Z-Wave has the ability to be compatible with all, regardless of which transmission layer is being used (Z-Wave over IP is already available to developers). One good reason integrators should be paying attention to Z-Wave is we’re the only standard with a 1,500 certified product ecosystem with 50 million devices currently in the marketplace.
