The Shelly Qubino Wave Pro 3 is a three-phase, 3-channel relay supporting up to 48 A across two outputs of 16A each. This device is designed to be mounted on the DIN-rail of the junction box, offering professional-grade control over pre-existing electrical appliances and systems such as dynamic smart lighting and efficient climate control. The Wave Pro 3 can also significantly reduce operational costs in workspaces by deactivating power to non-essential, high-consumption electrical appliances automatically. The Shelly Qubino Wave Pro 3 operates on Z-Wave, and is compatible with any Z-Wave gateway, meaning it's natively compatible with pre-existing smart home and office systems. The Wave Pro 3 includes a sophisticated suite of security protocols to keep your smart network secure, and can establish direct communication between Z-Wave devices and set actions even without the presence of a hub. **Please note:Z-Wave gateway (smart hub) is sold separately. A Z-Wave gateway is required to configure the device.
