Description
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.
The device can function standalone within a local Wi-Fi network or can be integrated with cloud home automation services. As long as the device remains connected to a Wi-Fi router and the Internet, users gain the flexibility to access, control, and monitor their lighting configurations from virtually anywhere.
Designed with adaptability in mind, Shelly 2L Gen3 is engineered to snugly fit within standard electrical wall boxes, be discreetly placed behind light switches, or in other areas where space might be a limiting factor. An added benefit is its embedded Web Interface, which allows users to not only monitor and control their lighting but also to fine-tune the Device settings with ease.
This device is Matter ready, this functionality can be added with firmware update.
