Shelly Bypass R2 (accessory to Shelly 1L and Shelly Dimmer 2)

New Shelly Bypass R2 version, released in September 2022, is an accessory from Shelly which works together with Shelly 1L single-live-wire WiFi smart relay, and Shelly Dimmer 2 single-live-wire WiFi Smart dimmer relay. Use of Shelly Bypass is only required if small power consumption lights are used with the smart relays (such as LED lights).

Specifically, if:

• Shelly 1L is used with a light or other electric device with lower performance than 20W, or
• Shelly Dimmer 2 is used with a light with lower performance than 10W.

It is only required when Shelly 1L or Shelly Dimmer 2 is used in single-live-wire installation, that is, without neutral wire.
