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,[1] 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.[2][3] 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 computers, with a Z-Wave gateway or central control device serving as both the hub controller and portal to the outside.[2][4] 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.[5]
