2 Channel Zigbee Retrofit Relay

The 2 Channel Retrofit Relay converts two standard mechanical switches into independently controllable smart switches from a single compact module. Each channel operates on its own — a fan and a light, two separate room circuits, or any combination — all managed through schedules, voice commands, or automation rules while keeping your existing switch plates intact. Each channel handles direct load switching up to 4A, covering most residential lighting and fan loads. The dual-channel design means fewer modules behind the wall, simpler wiring, and lower cost per controlled circuit. At just 40 x 40 x 18 mm, it fits comfortably in standard Indian flush boxes alongside the existing wiring. Communication runs over Zigbee 3.0, contributing to the mesh network that strengthens whole-home coverage. Integrates natively with Home Assistant and supports Matter and Apple HomeKit through a compatible hub. An efficient choice for rooms where two circuits share a common switch board — bedrooms with separate light and fan controls, bathrooms with light and exhaust, or any paired load scenario.
