The Shelly Bypass is the technical component needed to complete home automation installations where there is no neutral wire in the switch box.

Shelly Bypass: Stability for Shelly 1L and 2L (Gen3 Series)

Designed to work in perfect harmony with the new generation of Shelly devices, this accessory ensures that the relay receives the necessary power to stay connected to the Wi-Fi network, even when the lights are off, eliminating flickering or misfires in low-consumption bulbs.

Technical Specifications

• Power Supply: 240 V ~ 50 Hz.

• Device Compatibility: Shelly 1L Gen3, Shelly 2L Gen3, and Shelly Dimmer Gen3.

• Usage Condition: Mandatory in installations without neutral wire with loads under 20W.

Advantages and Applications

This accessory is the "lifesaver" solution for modernizing old homes. Its main application is to allow Shelly 1L and 2L Gen3 relays to function correctly in high-efficiency LED lighting circuits (which typically consume much less than 20W).

By installing the bypass in parallel with the load, a minimum current flow is ensured that keeps the smart chip active without turning on the bulb, offering a robust and professional smart home experience without the need to rewire the entire house.
