Description
The SM323-WF module is the bare PCB version of our SM323 Wi-Fi dimmer – the same hardware used in the SM323-WF plate-bundled variants, supplied without a faceplate or knob. Designed for installers and customers who already own a designer wall plate, or who want to retrofit smart Wi-Fi control inside an existing UK wall switch.
