Wi-Fi or Zigbee smart switches for a finished 3BHK in Bangalore?
Your 3BHK is already plastered and painted, and you want smart switches without breaking walls. Here is how our Wi-Fi series (EI, EX, PX) and Zigbee series (ZXD, ZXC) compare, with SmartLoka panel prices.
Your 3BHK is finished and you want smart switches without breaking walls
Short answer: pick Wi-Fi if you want the lower cost and no separate hub; pick Zigbee if you want the switches on their own local network with a gateway. Both go into a finished 3BHK without chasing walls. Our Wi-Fi series are EI, EX and PX; our Zigbee series are ZXD and ZXC.
Price your 3BHK on the automation planner: it shows all five series side by side.

| Series | Network | What it is | Panel price (SmartLoka, incl. GST) |
|---|---|---|---|
| EI | Wi-Fi | Insert modules behind your existing switch plates | ₹3,466 – ₹5,839 |
| EX | Wi-Fi | EX/PX series | ₹5,880 – ₹10,272 |
| PX | Wi-Fi | EX/PX series, customised icons, RGB backlighting (one ON/OFF colour per panel) | ₹9,466 – ₹16,433 |
| ZXD | Zigbee | Edge series, dual-indication blue/white | ₹11,480 – ₹19,462 |
| ZXC | Zigbee | Edge series, RGB edge | ₹12,838 – ₹22,616 |
The trade-offs
- Wi-Fi (EI, EX, PX): no separate hub, and the lowest entry price. Each switch joins your home Wi-Fi, so router coverage matters in every room.
- Zigbee (ZXD, ZXC): the panels talk to a Zigbee gateway, so the switches sit on their own local network. The package adds the gateway, which raises the price.
- Keeping your plates: only EI keeps your existing switch plates. An electrician checks box space, wiring and each load first.

Questions people ask
Should I choose Wi-Fi or Zigbee smart switches for a finished 3BHK?
Both fit a finished home without breaking walls. Wi-Fi (our EI, EX and PX series) needs no separate hub and is the lower-cost route. Zigbee (our ZXD and ZXC series) adds a gateway and keeps the switches on their own local network. The automation planner prices both for a 3BHK so you can compare.
Which of your switch series are Wi-Fi and which are Zigbee?
EI, EX and PX are Wi-Fi. EI uses insert modules behind your existing switch plates. EX and PX are the EX/PX series panels: EX with standard icons, PX with customised icons and RGB backlighting. ZXD (dual-indication blue/white edge) and ZXC (RGB edge) are Zigbee.
Do Zigbee switches need a hub?
Yes. ZXD and ZXC panels work with a Zigbee gateway, and our Zigbee packages include the gateway quantity the catalogue returns. The final gateway count is confirmed after a coverage review.
Can I keep my existing switch plates?
With the EI series, often yes. EI modules sit behind your existing plates. An electrician must first check switch-box space, the available wiring and each load.
