Shelly Bypass for 1L/2L

Overview

The Shelly Bypass for 1L / 2L is a compact load-balancing accessory designed to enable proper operation of Shelly relays in no-neutral wiring installations. It is required when using Shelly 1L or Shelly 2L devices in circuits where the connected load is too small to allow stable operation.

By installing the bypass in parallel with the load, it ensures sufficient current flow for the relay to function reliably, preventing flickering, unstable switching, or device resets—especially common with low-wattage LED lighting.

Key Features

• Required for no-neutral installations with Shelly 1L and Shelly 2L
• Enables stable operation with low-power loads (e.g. LED lights)
• Prevents flickering and unreliable switching
• Compact, in-line design for easy installation
• Simple passive component (no configuration required)
• Compatible with Gen3 devices

Installation Notes

• Installed in parallel with the load (typically at the light fitting)
• Required when the connected load does not meet the minimum wattage
• Must be installed by a qualified person if working with mains voltage
• Does not affect normal operation once installed
