Z-Wave is a wireless communications protocol used primarily for home automation. It is oriented to the residential control and automation market and is intended to provide a simple and reliable method to wirelessly control lighting, HVAC, security systems, home cinema, automated window treatments, swimming pool and spa controls, and garage and home access controls. Like other protocols and systems aimed at the home and office automation market, a Z-Wave automation system can be controlled via the Internet, with a Z-Wave gateway or central control device serving as both the Z-Wave hub controller and portal to the outside. Z-Wave was originally developed by Danish startup Zen-Sys and later acquired by Sigma Designs in 2008. There are over 1,500 interoperable Z-Wave products marketed under different brands, and over 35 million have been sold since 2005.
The 1,500 devices that make up the Z-Wave product portfolio are each designed by brands with membership in the Z-Wave Alliance. The alliance is a formal association focussed on both the expansion of Z-Wave and the continued interoperability of any device that utilises Z-Wave. Principal members of the alliance include the ADT Corporation, FAKRO, Ingersoll Rand, Jasco, LG Uplus, Nortek Security & Control, Sigma Designs, and Samsung's SmartThings. In October, 2013, Sigma Designs and the Z-Wave Alliance announced a new protocol and interoperability certification program called Z-Wave Plus, based upon new features and higher interoperability standards bundled together and required for the 500 series system on a chip (SoC), but encompassing some features that had been available since 2012 for the 300/400 series SoCs. In February, 2014 the first product was certified. In December, 2015 Sigma Designs announced the 2016 release of an update to Z-Wave Plus, dubbed Security 2, focussed on enhancing Z-Wave's core security features and allowing Z-Wave devices to receive the UL certifications necessary for use by the security industry.
