Shelly Bypass - Bypass Module, Black

The Shelly Bypass Module is a component for smart lighting systems that lack a neutral wire. It provides a controlled dummy load to ensure the connected switch remains powered. By regulating the electrical current, the module resolves issues such as LED flickering or unstable fixture behaviour. It is used to achieve consistent switching and smooth dimming in buildings with traditional wiring, ensuring compatibility for energy-efficient bulbs in neutral-free circuits.

This bypass is designed for use with specific Shelly relays. It operates on standard 230 V electrical systems to stabilise circuits. It is wired in parallel with the lighting circuit to manage modern LED lamps. This allows automated routines to function without requiring extensive modifications to a building's core wiring, ensuring the relay remains online and responsive to network commands even when the light is switched off.

• Compatible with Shelly 1L and Dimmer 2 – Designed for use with these relays in neutral-free setups.
• Supports loads under 20 W – Stabilises low-power LED lamps that do not meet the primary switch's minimum requirements.
• 4 W typical power consumption – Draws minimal energy while keeping the smart switch powered.
• 23x13x39 mm footprint – Compact enough to fit behind existing switches in standard electrical wall boxes.
• Black plastic housing – Provides insulation for safe operation within enclosed spaces.
