The Shelly Bypass is an addition to the Shelly Dimmer 2 or Shelly 1L. The Shelly Bypass is required when the minimum load of the Shelly relay is below when connected without neutral conductor. If the connected load of the Shelly Dimmer consumes less than 10 W or Shelly 1 L less than 20 W, the Shelly Bypass must be switched parallel to the load.
