Z-Wave is a wireless communication protocol designed for smart home devices. It enables various devices, such as lights, locks, and sensors, to connect and communicate with each other. Operating on a low-frequency band, Z-Wave is known for its reliability and energy efficiency, making it ideal for home automation. One of the key features of Z-Wave is its mesh networking capability. This means that devices can relay signals to one another, extending the range of the network. As a result, even devices that are far from the main controller can still communicate effectively, enhancing the overall functionality of a smart home system.
