AJAX Smart Home LightCore 2-Gang Smart Switch Module 52137

The AJAX Smart Home LightCore 2-Gang Smart Switch Module (model 52137) is a compact, two-channel relay module designed for seamless integration into existing electrical installations. It enables remote control and automation of lighting and other resistive/capacitive loads via the Ajax Jeweller wireless protocol, with a range of up to 1,100 m in open space. The module fits behind standard switches in wall boxes (Ø60 mm, 40 mm depth) and works with traditional mechanical switches (push-button or toggle). It supports energy consumption monitoring, overload, overheating, and voltage surge protection. Requires an Ajax Hub (Hub 2, Hub 2 Plus, Hub Plus, or Hub) for operation.

Advantages

Easy retrofit installation behind existing switches; two independent channels for controlling two circuits; reliable Jeweller wireless communication with long range; comprehensive protection features; energy monitoring for efficiency; works with Ajax app and automation scenarios.

Suitable for

• Smart home lighting control
• Automation of resistive loads (e.g., incandescent lamps, heaters)
• Capacitive loads (e.g., LED drivers, electronic transformers)
