Z-Wave communication protocol smart sockets
Z-Wave
— a wireless communication standard specifically designed for automation and control systems, including alarms and smart homes. Along with ZigBee (see the relevant paragraph) is one of the generally accepted protocols used in such systems; and in smart sockets controlled through the control unit, it is also the most popular. This is due to the fact that such a connection is simple and inexpensive to implement, while being quite functional and practical. It provides the transmission of the most simple and short control commands, which helps to save energy, and operates in the range up to 1 GHz, so it is not subject to interference from Wi-Fi and Bluetooth devices.In addition, in networks based on Z-Wave, it is possible to use a MESH type topology — when each individual device is also a full-fledged repeater of signals from other system components. The main advantage of such a topology is the ability to choose any signal route through any number of intermediate nodes, depending on the situation. For example, if for some reason a direct connection between two nodes turned out to be impossible, the data will be sent “bypass”, through other network devices, and the system will automatically determine the most optimal route. This makes it easy to organize extensive networks with numerous devices and a large area of coverage.
