What Controls Does a Basic Home Automation Need?
After "what is automation?", the next question we hear is: what controls do we actually need for a basic automation? People worry that it is all or nothing. It is not. A good system starts with a few controls the family uses every day, and leaves room to grow.
A basic system covers four controls: lighting, curtains and blinds, air-conditioning and fans, and wall keypads with scenes.
A phone app and schedules are included with any professional system.
Everything else can wait (music, home theatre, cameras, door locks), as long as the conduits and network points are planned before the walls are closed.

The four basic controls
| Control | What it does | Why it belongs in a basic system |
|---|---|---|
| Lighting | Switches and dims each group of lights | Used more than anything else in the house; scenes are built on it |
| Curtains and blinds | Opens and closes motorised curtains and blinds | Daylight, privacy and heat control with one button |
| Air-conditioning and fans | Sets the temperature and switches rooms on and off | Comfort, and no empty room left cooling all day |
| Keypads and scenes | Engraved wall buttons such as Welcome, Dinner, Good Night and All Off | The part every family member and guest can use without a phone |
1. Lighting
Lighting is where automation starts, because it is what you touch most. Each group of lights (cove, downlights, wall lights, a chandelier) becomes one controlled circuit that can be switched, and dimmed where the fittings allow it. Once the lights are on the system, scenes become possible: "Dinner" is simply a saved set of levels for every light in the room. If a budget allows only one control, this is the one. See lighting control.
2. Curtains and blinds
Motorised curtains and blinds open with the morning scene, close at sunset and shut with "Good Night". In our climate they also keep the afternoon heat out. They need a power point and a control cable at each window pelmet, which is easy during construction and awkward afterwards, so decide early even if the motors come later.
3. Air-conditioning and fans
Linking the air-conditioning lets a scene set the temperature, lets you cool the bedroom before you arrive and makes sure "All Off" really means everything. Fans can be switched and speed-controlled in the same way.
4. Keypads and scenes
A keypad replaces a long plate of switches with a few engraved buttons. This is what makes automation simple for everyone: a guest can read "Reading" or "All Off" and press it. A phone app is useful from the sofa or from another city, but the keypad is what gets used all day. Scenes most families start with: Welcome, Dinner, Movie, Good Night and All Off.
A phone app and time schedules (garden lights at sunset, everything off at midnight) come with any professional system, so they are not extra items to choose. Voice control through a voice assistant can be added on top.
What sits behind them
Three things you rarely see decide how well the house behaves:
- The controller and modules in the electrical panel, where the scenes and schedules live. They run inside the house, so the keypads work even when the internet does not.
- A properly designed home network, wired to each Wi-Fi point, so the app works in every room.
- Clean, backed-up power for the equipment. We recommend that you provide a UPS; see how automation handles a power cut.
What can wait
None of the following is needed on day one, and all of it can join the same system and the same app later:
- Multi-room music and a home theatre
- Cameras and the video door phone
- Smart door locks and gate control
- Sensors that switch lights with movement or daylight
- Garden, facade and water-feature control
The one condition is provision: the conduits, speaker cables and network points for them must go in before the walls and ceilings are closed. Provision costs little during construction; adding it later means breaking finished surfaces.
What to decide before construction
- Wired or wireless. For a home under construction, wired KNX is the first choice and the most cost-effective professional system. For a finished home, professional wireless avoids opening the walls; see how Zigbee and Z-Wave differ from Lutron's RF.
- Which lights are grouped together, and which are dimmed.
- Where the keypads go, and what each button is called.
- Which windows get motorised curtains, now or later.
- Where the equipment sits: the panel, the network rack and their backup power.
Our construction-stage checklist lists what to decide and when. We design for 3BHK homes and above, and every system is quoted on your own plan.

Frequently Asked Questions
What controls does a basic home automation system need?
A sensible basic system covers four things: lighting (on, off and dimming), motorised curtains or blinds, air-conditioning and fans, and wall keypads with scenes such as Welcome, Dinner and Good Night. A phone app and schedules come with any professional system. Music, home theatre, cameras and door locks can be added later if the wiring and network are planned for them at the start.
Can I start with lighting only?
Yes. Lighting control with wall keypads and scenes is the smallest system that still feels like automation, and it is the part a family uses most. Curtains and air-conditioning can join later, provided the conduits, power points and cables for them are put in while the home is being built.
Do I need the internet for a basic system to work?
No. In a professional KNX, Crestron or Lutron system the keypads, scenes and schedules run from equipment inside the house. The internet is needed only to control the home from outside and for voice assistants.
Can I add music, cameras or a home theatre later?
Yes. These join the same system and the same app later. The condition is provision: conduits, speaker cables and network points must be planned before the walls and ceilings are closed, because adding them afterwards means breaking finished surfaces.
Is a phone app enough, or do I still need keypads?
You need keypads. An app is useful from the sofa or away from home, but nobody wants to unlock a phone to switch on a light, and guests, elders and staff will not have the app. Engraved wall keypads are what make the home easy for everyone.
Which system is best for a basic setup?
For a home under construction, KNX is the most cost-effective professional choice and covers all four basic controls well. Lutron is chosen where lighting and dimming quality matter most or the home is already finished, and Crestron where one app must also run audio-visual, climate and security across a large home.
Is basic automation worth it for a 3BHK?
Yes. We design for 3BHK homes and above. In a 3BHK the four basic controls already remove most daily switching: one button at the door for Welcome and All Off, scenes in the living room and curtains and air-conditioning set from the bedside.
