Smart Relay Switches

Relay switches from Shelly deliver reliable on/off control for lights, appliances, garage doors, and heating systems. These smart relays retrofit behind existing switches without rewiring, supporting 8A to 48A loads across residential and commercial applications. Wi-Fi models operate hub-free with local control, while Z-Wave variants enable mesh networking. Professional DIN-rail units feature dry contacts and UL certification for demanding installations. Power monitoring versions track energy consumption alongside switching control.
