NEXA 4+1 Switch (10A Relay + Fan Dimmer) — Smart Multi-Load & Fan Controller

The NEXA 4+1 Switch (10A Relay + Fan Dimmer) is a powerful retrofit automation module that enables wireless smart control of four electrical loads and one ceiling fan — all without changing your existing switchboard. Once installed behind the panel, the device connects to the mobile app and major voice assistants including Alexa, Google Assistant, and Siri.

Each of the four 10A relays can independently control appliances such as lights, lamps, LEDs, decorative fixtures, and small home appliances. The built-in dimming channel enables smooth ceiling fan speed control. Users can automate routines, set timers, create scenes, remotely turn loads on/off, and track usage history — providing comfort, convenience, and energy savings.

Its rugged hardware and secure wireless connectivity make it ideal for homes, offices, hotels, and commercial installations seeking rich automation without rewiring.
