Shelly 2L Gen3 is a compact, two-channel smart switch tailored for precise lighting control. A standout feature of this device is that it doesn't require a Neutral wire to operate. However, it needs a Shelly Bypass 1L/2L Gen3 connected in parallel to the load at the first channel. Shelly 2L Gen3 allows users to effortlessly control their lighting setups through a mobile phone, tablet, PC, or integrated home automation system.
