Z-Wave controller
also: Z-Wave hub, Z-Wave gateway
A Z-Wave controller is a device or software that manages wireless communication with Z-Wave smart home devices, acting as the central hub that sends commands and receives status updates from Z-Wave nodes.
A Z-Wave controller is the central coordinator in a Z-Wave mesh network, responsible for initiating and managing all wireless communication with Z-Wave devices. It operates on the 2.4 GHz frequency band and can control lights, locks, sensors, thermostats, and other smart home devices.
On Linux systems, Z-Wave controllers are typically accessed through USB dongles or dedicated hardware that runs Z-Wave software. Popular Linux-based Z-Wave solutions include OpenZWave, zigbee2mqtt, and integration with home automation platforms like Home Assistant.
Example: You plug a Z-Wave USB stick into your Linux home server running Home Assistant, which automatically discovers and manages all your Z-Wave light switches, door locks, and sensors on your network.
