Shelly 2L Gen3 Dual-Channel WiFi Smart Switch for No-Neutral Lights

The Shelly 2L Gen3 Dual-Channel WiFi Smart Switch represents a significant advancement in smart lighting control, specifically engineered for installations where a neutral wire is not available. This compact device provides independent control over two separate lighting circuits, making it an ideal solution for modernising existing lighting setups without the need for extensive rewiring. Its ability to function without a neutral connection is facilitated by the parallel installation of a Shelly Bypass 1L/2L Gen3 at the first channel's load, ensuring reliable operation even with lower-wattage bulbs.

Designed for seamless integration into both new and retrofit applications, the device fits discreetly within standard electrical wall boxes or behind existing light switches. Users can manage their lighting through multiple interfaces including mobile applications, web browsers, or voice commands when integrated with popular smart home platforms. The embedded web interface provides direct access for monitoring and configuration, while Matter compatibility ensures future-proofing through firmware updates. Operation is supported in both local network modes and cloud-connected environments, offering flexibility for various home automation scenarios.
