Description
The Shelly 2L Gen3 is a compact, two-channel smart switch designed for precise lighting control in installations without a neutral wire. Ideal for retrofits in older homes, it allows you to control two lighting loads independently, without the need for electrical restructuring. Compatible with most wall switches, it easily integrates into home automation systems via Wi-Fi or Bluetooth. It includes overheating protection and allows OTA updates. The Shelly 2L Gen3 is Matter compatible (via firmware update) and comes with a Shelly Bypass 1L/2L included to allow operation with LED loads.

FEATURED FEATURES
✅ Smart control without neutral wire
The Shelly 2L Gen3 is designed for neutral wire-free installations, which are common in many homes. With the included Shelly Bypass 1L/2L, you can reliably control low-power LED loads without modifying existing wiring.
✅ Two independent channels
Allows you to control two separate lighting loads, with a maximum power of 200W on channel O1 and 700W on channel O2.
✅ Wi-Fi and Bluetooth connectivity
Wi-Fi connectivity ensures local and remote control without the need for an additional hub. Bluetooth facilitates initial setup and can act as a gateway for Shelly BLU sensors.
✅ Compatible with Matter and local automations
With support for the new Matter standard (via firmware update), Shelly 2L Gen3 offers greater interoperability with modern home automation platforms. It also supports local scenes, timers and offline control via Wi-Fi.
✅ Security and reliability
Equipped with a temperature sensor to detect overheating, the Shelly 2L Gen3 guarantees safe and reliable operation in residential environments, as long as it is installed correctly and protected by a 10 A circuit breaker (with curve B or C).

◾ Shelly 2L Gen3
◾ Shelly Bypass 1L/2L Gen3
◾ Installation manual
NOTES
◾ The Shelly 2L Gen3 is powered through O1. If this channel is connected to an LED load, it is necessary to turn on the Bypass on that load. If the load on O1 is incandescent, it will not be necessary to turn on the Bypass.
◾ Does not support low-voltage LED lighting power supplies (may cause unstable behavior or relay failure).
◾ The Shelly 2L Gen3 is prepared to use the Matter protocol, but to use this functionality it is necessary to update the firmware.
