Shelly 1L Gen3 No-Neutral Smart Relay Switch

Shelly 1L Gen3 is an advanced single-channel smart relay without neutral wire requirements. It is specifically engineered for lighting control in buildings where a neutral line is missing at the switch box. The device fits neatly inside standard in-wall junction boxes. Therefore, it is the absolute perfect retrofitting solution for older homes and apartments without undergoing expensive rewiring jobs.

Smart lighting control without any wall modifications

Once installed, you can manage your lights remotely from anywhere across the globe. The software allows you to configure advanced custom schedules. Furthermore, you can create automations based on local sunrise and sunset times. The relay connects directly to your standard Wi-Fi network. Consequently, it operates completely standalone without requiring a separate proprietary hub.

This single-wire relay can solve unique legacy lighting problems. For instance, you can use it for the following automation cases:

• Turning old traditional chandeliers into smart lights while keeping your original wall switches
• Ensuring hallway lights switch off automatically after a set period of time
• Controlling your light fixtures using hands-free voice commands via smart assistants

Included Shelly Bypass for flawless LED performance

A genuine Shelly Bypass 1L/2L Gen3 is included inside this retail package. It connects in parallel to your light fixture load. In fact, this module is required for all modern low-wattage LED bulbs over 5W to eliminate light flickering or glowing. However, if you are controlling traditional incandescent bulbs, the bypass module is not required at all.

Future-proof home automation with Matter support

The third-generation (Gen3) hardware features upgraded processing speeds and highly reliable wireless connections. It comes Matter-ready. This native connection to Apple HomeKit, Google Home, and Alexa is enabled via a simple over-the-air firmware update. Additionally, the unit contains an internal temperature sensor for overheating protection. This feature guarantees safe and durable operation inside your walls.

Technical safety notice for users

Because this smart relay connects directly to 220-240V mains power, professional installation by a qualified electrician is strongly recommended. Always disconnect the main circuit breaker before starting any hardware installation work.
