Planning home automation for 2BHK and 3BHK homes works best room by room. Instead of automating everything at once, decide which rooms you use most and which functions save the most effort, then build your budget around them. This approach keeps costs under control and gives you a system that grows with your family.
Here is a practical room-by-room plan for typical Chennai and Tamil Nadu apartments and compact independent houses, with ideas for what to prioritise and what can wait.
Start with Priorities, Not Products
- Who lives in the home — working couple, children, elderly parents?
- What do you find most annoying today: walking to switches, forgetting to turn off ACs, worrying about the door?
- Is the home new or already finished?
- Is it rented or owned? Renters may prefer plug-in and wireless devices that can move with them.
Answering these questions first stops you from buying gadgets that look impressive but are rarely used. A family with elderly parents might value automatic night lights and a simple keypad lock far more than colour-changing bulbs, while a working couple may care most about AC schedules and checking the door from the office.
Living Room: The Highest-Value Room
The living room is used by everyone and is where smart lighting and scenes make the biggest impression. Consider smart switches for main lights and fans, a ‘Movie’ or ‘Guests’ scene, IR control for the TV and AC, and motorised curtains if the room has large windows.
In most 2BHK and 3BHK flats, the living and dining areas share one open space, so a single touch panel near the entrance can control lights, fans and curtains for both. Keep at least one manual switch for each main light, so guests and domestic staff are never left in the dark if they do not use the app.
Bedrooms: Comfort and Sleep
Master bedroom
Bedside control of lights and fans, AC scheduling and a ‘Good night’ scene that turns off the whole house are popular choices. In Chennai’s heat, AC automation with timers and temperature schedules is often one of the most appreciated features.
Second and third bedrooms
Children’s rooms and guest rooms can start with simple smart switches and AC control, with more added later. In a 3BHK, a third bedroom used as a study may only need lighting control.
Entrance and Security
- Digital door lock with fingerprint and PIN for keyless entry.
- Video door phone or video doorbell to see visitors.
- A door contact sensor or Ajax alarm kit if the home is often empty.
- An entrance light that turns on automatically when you arrive at night.
For apartments, check the association rules before fixing anything outside your door, such as a video doorbell in the common corridor. For compact independent houses, the entrance plan may also include the compound gate, which can later be automated and linked to the video door phone.
Kitchen, Utility and Balcony
These areas usually need less automation. Useful additions include a smart plug or switch for the water heater or motor pump, a leak sensor near the washing machine and a smoke detector in the kitchen. Balcony lights can follow a sunset schedule.
Leave electrical work on geysers and pump motors to a qualified technician, since these are high-load circuits and must be wired with the correct relays and protection. Avoid opening distribution boards or motor starters yourself.
| 2BHK priorities | 3BHK priorities | |
|---|---|---|
| Phase 1 | Living room lights, fans, master bedroom AC | Living room scenes, master bedroom, entrance lock |
| Phase 2 | Digital lock, video door phone | Other bedrooms’ AC and lighting, video door phone |
| Phase 3 | Second bedroom, curtains | Curtains, security sensors, kitchen safety |
| Hub planning | Usually one hub covers the flat | One hub, check coverage for larger layouts |
Building Your Budget by Room
- 1List every room and the functions you want in each.
- 2Mark each function as must-have, nice-to-have or later.
- 3Ask your installer to price must-haves first, room by room.
- 4Add backup for the hub and router on the inverter circuit.
- 5Review the quote with your family before adding nice-to-haves.
Room-by-room pricing makes it easy to see where your money goes and to move items between phases without redesigning the system.

Frequently asked questions
Is home automation worth it for a 2BHK flat?
Yes, especially for lighting, AC control and a digital door lock, which you use every day. Starting with a few rooms keeps the investment manageable.
Which room should I automate first?
Most families start with the living room and master bedroom, since these are used most. The entrance, with a digital lock or video door phone, is another popular early choice.
Can I automate a rented 2BHK or 3BHK?
Yes, using plug-in devices, wireless switches and IR controllers that can be removed when you move. Always check with your landlord before changing fixed wiring.
Do I need a hub for home automation in a 3BHK?
It depends on the platform. Zigbee systems need a hub, while Wi-Fi devices connect directly to your router; one hub usually covers a typical 3BHK flat.
