Where you'd use it
Enabling low-wattage no-neutral circuits
Fit alongside a Shelly 1L on a circuit with only one or two LED downlights, where the load alone isn't enough to power the switch reliably without a bypass.
Fixing flicker on retrofitted dimmers
Pair with a Shelly Dimmer 2 or Dimmer Gen3 in a no-neutral back box to stop lights flickering or failing to switch off fully.
Spare part for multi-room rollouts
Keep spares on hand when fitting several Shelly 1L or Dimmer Gen3 switches across a no-neutral property, since each installation needs its own bypass.
