How Smart Switches Work Behind the Wall: A Technical Walkthrough

Smart homes are gaining popularity across India as more people seek easy control over their home appliances. Iotics, based in Coimbatore, offers a range of smart WiFi switches for home automation, delivering convenience, energy efficiency and style to modern Indian households.

What Are Smart Switches?

A smart switch is a modern replacement for your traditional wall switch. Instead of simply turning lights and fans on or off, smart switches let you control them using:

• Mobile apps (via WiFi)

• Voice commands (Google Assistant / Alexa)

• Remote controls

• Manual touch on the switch itself

• Timers and schedules

Iotics offers smart touch WiFi switches that fit into the same place as your old switches but give you much more power and control.

What’s Inside a Smart Switch?

Inside an Iotics smart switch, there are four key components:

1. Capacitive Touch Panel

This is the sleek outer layer that you touch to control the lights or fans. It's similar to your smartphone screen and adds a premium feel to your wall.

2. Microcontroller Unit (MCU)

This is like the brain of the switch. It processes your touch or mobile commands and sends signals to the relays.

3. Relay Mechanism

The relay acts like a smart switch inside the switch. It opens or closes the electrical connection to your appliance based on your commands.

4. WiFi Module

This connects the switch to your home WiFi network. Once connected, you can control it through the Iotics app from anywhere in the world.

How Does It Work Behind the Wall?

Step-by-Step Working:

1. Touch or App Input – You touch the panel or use the app to turn on a device.

2. Signal Processing – The MCU processes the input.

3. Relay Activation – The microcontroller signals the relay to open or close the circuit.

4. Electrical Current Flow – The relay allows or blocks electricity to the appliance (like a light or fan).

5. WiFi Updates – The change is sent to the Iotics app so you always know what’s on or off.

It all happens instantly and the outer design remains sleek while the real magic happens behind the wall.
