Z wave specification pdf

Z-Wave is a wireless communications protocol used primarily for home automation. It is a mesh network using low-energy radio waves to communicate from appliance to appliance, allowing for wireless control of residential appliances and other devices, such as lighting control, security systems, thermostats, windows, locks, swimming pools and garage door openers. Like other protocols and systems aimed at the home and office automation market, a Z-Wave automation system can be controlled via the Internet from a wireless keyfob, a wall-mounted keypad or through smartphones, tablets or z wave specification pdf, with a Z-Wave gateway or central control device serving as both the hub controller and portal to the outside.

It provides interoperability between home control systems of different manufacturers that are a part of its alliance. As of May 2017, there are over 1,700 interoperable Z-Wave products. The Z-Wave protocol was developed by Zensys, a Danish company based in Copenhagen, in 2001.

Its 100 series chip set was released in 2003, and its 200 series was released in May 2005, with the ZW0201 chip offering a high performance at a low cost. Its 500 series chip, also known as Z-Wave Plus, was released in March 2013, with four times the memory, improved wireless range, and improved battery life. The technology began to catch on in North America around 2005, when five companies, including Danfoss, Ingersoll-Rand and Leviton Manufacturing, adopted Z-Wave. They formed the Z-Wave Alliance, whose objective is to promote the use of Z-Wave technology, with all products by companies in the alliance interoperable.

16 million third seed round for Zensys. In May 2006, Intel Capital announced that it was investing in Zensys, a few days after Intel joined the Z-Wave Alliance.
