About this product
Shelly Bypass is a passive wiring accessory needed when a no-neutral Shelly device switches a load below 20 W at 240 VAC. At very low power, LED lamps may flicker or glow faintly when off (ghost glow), and the relay may not switch off cleanly.<br><br>The module connects in parallel with the load (the lamp) and provides the minimum current the Shelly relay needs to operate reliably. Working voltage 230 VAC, consumption under 4 W, size 39x23x13 mm. Compatible with Shelly 1L and Shelly Dimmer 2.<br><br>Important: this is an accessory used together with a Shelly device, not a standalone product. Installation must be performed by a qualified electrician.

Where it works
Use cases
Living room with a low-power LED chandelier; the bypass removes ghost glow in the off position.
Shelly Dimmer 2 feeds dimmable LEDs that glow when off.
Bedroom where an LED night lamp stays faintly lit; the bypass supplies the relay minimum current.
A weak LED fixture on a no-neutral circuit does not switch off fully.

Frequently asked questions
What is the Shelly Bypass used for?
It is a passive accessory used together with a no-neutral Shelly device (Shelly 1L or Dimmer 2) when the LED load is below 20 W at 240 VAC, to remove flicker and ghost glow.Which Shelly devices is it compatible with?
The manufacturer officially lists the Shelly 1L and Shelly Dimmer 2, the Shelly devices that operate without a neutral wire.When do I need a bypass?
When you notice flicker or residual glow of LED bulbs on a no-neutral Shelly and the total load on the circuit is below 20 W at 240 VAC.How is the Shelly Bypass connected?
It is wired in parallel with the load (the bulb) and supplies the minimum current the Shelly relay needs. The work involves 230 V and must be done by a qualified electrician.Does the Shelly Bypass work on its own?
No. It is not a standalone product: the accessory only makes sense when installed together with the no-neutral Shelly device it complements.What are the dimensions and working voltage?
The module measures 39x23x13 mm without wires, works at 230 VAC and draws under 4 W, so it fits easily inside a switch box.
