Your Home Stays Smart.Even When the Internet Doesn’t.
SmartLink is an offline-first AI voice control system built for Indian homes. Voice commands run locally inside the module — so your home responds instantly, with or without Wi-Fi.
No cloud dependency for core controls. No smart speaker required. No rewiring needed.
THE PROBLEM
Most Smart Homes Fail When You Need Them Most
Every competitor’s “smart home” depends on the internet. When your Wi-Fi drops, router restarts, or ISP goes down — everything stops working.
Lights don’t respond
Voice commands fail
Apps disconnect
That's not smart. That's fragile.
THE SOLUTION
SmartLink Works Differently
Local Intelligence
The intelligence lives inside your home — not on a server somewhere.
Local Processing
Voice commands are processed locally. No cloud delays or dependencies.
Total Responsiveness
Controls stay responsive. Your home keeps working — no matter what happens to your internet.
Offline-First AI Voice Control
Control your home using voice — without relying on the cloud. SmartLink uses an embedded AI voice model running directly on the module to recognize commands and respond instantly.

Frequently Asked Questions
What is the SMARTLINK retrofit module?
SMARTLINK by NKSPAIR is a compact, intelligent device designed to fit seamlessly behind your existing switchboards. It instantly upgrades your traditional wiring into a complete smart home automation system, allowing you to control your lights, fans, and appliances remotely without altering your home’s aesthetic.
Do I need to replace my current switches to use SMARTLINK?
Not at all. The biggest advantage of a retrofit module is that you don't need to buy expensive new smart switches or do any major rewiring. SMARTLINK connects to your existing physical switches, transforming them into smart devices while letting you keep the tactile feel of your original switchboard.
How does SMARTLINK improve my daily routine?
By integrating SMARTLINK into your home, you unlock the full potential of smart home automation. You can schedule your geyser to turn on before you wake up, turn off all lights with a single voice command, or control your appliances via your smartphone from anywhere in the world. It brings convenience, energy efficiency, and modern luxury to your everyday life.
Can I still use my physical switches if the Wi-Fi goes down?
Yes! A common concern with upgrading to smart switches is losing control during internet outages. SMARTLINK is designed for reliability; your traditional physical switches will continue to work perfectly even if your Wi-Fi network is temporarily down.
Is the installation process for SMARTLINK complicated?
No, the installation is quick and straightforward. Because it is a retrofit module, it is designed to fit snugly inside standard electrical backboxes. We do recommend installation by a qualified electrician, but it typically takes just a few minutes per switchboard to bring your room into the smart home automation ecosystem.
Does SMARTLINK support voice control?
Absolutely. SMARTLINK is built to integrate with modern smart home setups, allowing for hands-free convenience. You can easily control your newly upgraded smart switches using simple voice commands, making it easier than ever to manage your home environment.
Can I start with just one room, or do I need to upgrade my whole house?
You can start as small as you like. SMARTLINK’s modular design means you can begin your smart home automation journey by upgrading a single room, like your living room or bedroom, and easily expand to the rest of the house whenever you are ready.
