WLAN-verlichtingscontroller Shelly Shelly_1L_Gen3 — 1-kanaals module zonder nulleider, 220–240 V, WLAN/Bluetooth, 802.11 b/g/n

Shelly_1L_Gen3 is a compact 1-channel WiFi lighting controller designed for single-circuit installations without a neutral wire. It supports 220–240 V AC mains and provides wireless control via Wi‑Fi (802.11 b/g/n) and Bluetooth. The module enables remote operation, timed switching tied to sunrise/sunset, script execution and webhook actions while drawing low power and offering overheat protection.

Advantages

The device is small and lightweight, suitable for installation behind switches or inside junction boxes. It offers multiple connectivity options (Wi‑Fi and Bluetooth) for flexible setup and remote control. Intelligent on/off, scheduling for sunrise/sunset, script support and webhooks allow integration with home automation systems. Built-in overheat protection and low maximum power consumption (1.2 W) make it energy-efficient and safe for continuous operation.

Suitable for

• Retrofitting conventional single-circuit lighting without a neutral wire
• Remote control of lights via mobile app or home automation platforms
• Scheduling lights based on sunrise/sunset times
• Integrating lighting with scripts and webhook-based automations
