Installation

Requirements

  • Existing wall switch in a flush box (≥ 60mm depth recommended)
  • Live, Neutral, and Load wires in the flush box
  • Zigbee coordinator within range

Turn off the circuit breaker for the affected circuit.

Remove the existing switch plate. The retrofit module sits behind the existing switch — no visible hardware change.

Connect wiring:

  • Live → L input
  • Neutral → N input
  • Load → load output(s)

Fit the module into the flush box. Use DIN rail adapters for panel board installation.

Replace the switch plate.

Restore power. The device will blink — ready to pair.

Pair with your Zigbee coordinator.

Load Limits

  • Standard relay: up to 4A direct. For 4–10A, use an external relay/SSR/contactor.
  • 40A relay: rated for direct high-current switching. Proper cable sizing and circuit protection mandatory.
  • Dimmer modules: resistive and leading-edge dimmable loads only. Not suitable for ceiling fans.

Shutter Module

The shutter module controls motorised curtains, blinds, and shutters:

  • M1, M2 → motor up/down terminals
  • Configure travel time in your coordinator for accurate position reporting.
