Shelly Bypass for Dimmer
£6.79
A bypass module used alongside the Shelly Dimmer Gen3+ in no-neutral lighting installations, helping the dimmer support low-wattage loads that a no-neutral wiring setup might otherwise struggle with. It's a passive accessory fitted as part of the dimmer installation rather than a standalone smart device.
- Designed specifically for no-neutral installations

Where you'd use it
Fixing No-Neutral Dimmer Flicker
Fit the Bypass for Dimmer alongside a Shelly Dimmer Gen3+ in a no-neutral installation to stop low-wattage LED downlights flickering or failing to switch off fully.
Enabling Neutral-Free Retrofits
Use it where an older UK lighting circuit has no neutral at the switch plate, so a Dimmer Gen3+ can still be fitted without rewiring back to the consuming circuit.
Note on limited source detail
The supplied product content is cut short and doesn't describe further functionality beyond enabling low-wattage loads on no-neutral circuits, so a third genuinely distinct use case cannot be safely grounded here.
