Shelly 2L Gen3 – intelligent relay without a neutral wire

Shelly 2L Gen3 is an advanced 2-channel lighting controller that represents a true breakthrough in the field of modernising electrical installations. This device allows for intelligent control of lighting even where there is no neutral wire in the junction boxes, making it an ideal solution for owners of older flats. Shelly 2L Gen3 supports devices with a power of up to 200 W on output terminal 1 and up to 700 W on output terminal 2. This gives you a smart lighting management hub without the need for chiselling walls or replacing wiring, making it suitable for almost any installation.

Installation and kit with bypass module

Installation of the Shelly 2L Gen3 module is possible in almost any flush-mounted box. Due to its compact dimensions, the device easily fits in limited space. The kit includes the necessary bypass module, which is particularly useful when working with modern LED sources with very low power. The bypass ensures stable power supply, prevents flickering of bulbs, and guarantees the highest safety of use. This means the module fits into almost any older type electrical installation, offering immediate access to modern features.

Lighting automation and scheduling

With Shelly 2L Gen3 you gain full control over the lighting in your home. The device allows you to create schedules based on sunrise and sunset, so Shelly will adjust the brightness and state of the lamps to your natural cycle. You can schedule the turning on and off of lights according to your daily routine or rhythm of the day. The system allows you to set automatic lighting when returning home and turning off lights according to daily energy-saving needs. Such precise automation means you no longer have to personally monitor lights according to your daily routine, significantly improving safety of use.

Wi-Fi, Bluetooth connectivity and protocol support

2L Gen3 is an advanced 2-channel controller equipped with a modern ESP-Shelly-C38F processor that ensures lightning-fast operation. Using Wi-Fi and Bluetooth connectivity, the device connects directly to your router without the need to purchase an additional hub. Thanks to Bluetooth, it is possible to pair the device quickly in seconds. Shelly 2L Gen3 supports advanced communication standards such as MQTTS, Web Sockets, and Web Sockets. This allows the relay to work seamlessly with many home automation systems, including the popular Home Assistant. Users can also upgrade to the premium version in the Shelly Smart Control app to access extended energy consumption analytics.

Safety and intelligent management

Shelly 2L Gen3 is an advanced relay that places great emphasis on protecting the installation. The built-in temperature sensor ensures that the module does not overheat when working with maximum load, ensuring safety of use. With 2L Gen3 you gain full control over two circuits, allowing for intelligent management of lighting safely and wirelessly. The device also supports advanced scripts and is ready for the Matter standard. You can manage it from your favourite iOS app, enjoying the functionality that this advanced 2-channel lighting controller offers.
