Smart switches replace or sit behind ordinary switches so you can control lights, fans, curtains and appliances by keypad, app, voice or schedule. Wireless smart switches suit apartments and retrofits, while wired KNX keypads suit villas and new builds. In India, they indicatively cost from about Rs 2,000 per switchboard to Rs 40,000 or more for a premium KNX keypad.

It’s 11 pm. The children are asleep, and someone starts the nightly walk: kitchen lights off, corridor off, living room cove off, balcony off. Then back to the bedroom, only to remember the study light is still on.

Now imagine the same home with smart switches. One “Good Night” button beside the bed switches off every light, closes the curtains and leaves a soft path light to the kitchen. The walk is gone.

Smart switches are the simplest way to bring automation into a home, because they work with the switches and lights you already understand. This guide explains the types, the partner brands we work with, what they cost and how to choose.

Who is this guide for?

• Apartment owners who want automation without rewiring
• Villa and new-build owners planning a complete smart home
• Families tired of smart bulbs that stop working when someone uses the wall switch
• Interior designers choosing switches that match premium interiors

What are smart switches?

Smart switches are switches or modules that control lights and appliances through a keypad, app, voice assistant or schedule, while still working like normal switches.

Unlike smart bulbs, they control the whole circuit, so every fitting on it becomes smart, including coves, downlights and profile lights. Our comparison of smart lighting automation vs smart bulbs explains why this matters. For the look and feel of glass touch panels versus regular switches, see touch switches vs traditional switches.

What types of smart switches are there?

There are four main types, and the right one depends on whether you are retrofitting or building new.

Which smart switch brands do we work with?

At Brightmatic, we design and install smart switches from ABB, Core and Hafele, each suited to a different type of home and system.

ABB is one of the most established names in building automation. Its Tacteo KNX keypads combine glass and metal finishes with clearly labelled scene buttons, while ABB-free@home offers a simpler route for apartments. See our ABB page.

Core focuses on designer finishes. Its Surface switches and smart touch panels suit homes where switches should look as good as the interiors. See our Core page.

Hafele brings smart control into furniture. Hafele Connect Mesh controls cabinet, wardrobe and kitchen lighting by app or switch. See our Hafele page.

What can smart switches control?

Most homes use smart switches for lighting first, then extend them to fans, curtains and appliances.

• Lights: on, off, dimming and lighting scenes
• Fans: speed control from keypad or app
• Curtains and blinds: with motorised tracks
• Geysers and ACs: with relays rated for heavy loads, plus schedules
• Outdoor lights: sunset timers for facade and garden lighting

Do smart switches need a neutral wire?

Many smart switches and modules need a neutral wire at the switchboard, so check before buying.

Older switchboards sometimes don’t have one. Some products are designed to work without a neutral, but with limits on the loads they can handle. Wired KNX systems avoid the problem, because power and control are handled by actuators in the electrical panel. A quick site check before choosing saves a lot of trouble later.

How much do smart switches cost in India?

Smart switches indicatively cost from about Rs 2,000 per switchboard for wireless options to Rs 40,000 or more for premium KNX keypads.

Are smart switches worth it?

• Is it expensive? Wireless options are affordable and can be added room by room. KNX costs more but runs the whole home reliably.
• Is it complicated? No. Everyone can still press the switch on the wall, and apps and voice are optional.
• What can go wrong? No neutral wire, underrated relays for heavy loads, weak Wi-Fi and mixing too many brands.

What mistakes should you avoid?

1. Buying switches without checking for a neutral wire
2. Using standard relays for geysers and ACs
3. Mixing several brands with separate apps
4. Choosing wireless for a large villa where stability matters
5. Installing keypads with unlabelled buttons
6. Forgetting to plan scenes before installation

A common myth: smart switches need an app to work. In reality, a good smart switch works like a normal switch first, with the app, voice and schedules as extras.

Expert recommendation from Brightmatic

For apartments and retrofits, we recommend wireless smart switches or retrofit modules, checked for neutral wiring and load ratings. For villas and new builds, we recommend wired KNX keypads from ABB or Core, with labelled scene buttons and actuators in the panel, plus Hafele Connect Mesh for furniture lighting. The KNX Association explains the KNX standard behind these systems.

Brightmatic designs and installs smart lighting control with switches and keypads from brands like ABB, Core and Hafele.
