Metro leave-now light
Timetable + live disruption + walk time + presence. Entrance light says leave, wait, or next train.
Worldwide · studios in Mumbai & Hong Kong
Every home
can be automated.
If it has a switch, a motor, a remote or a signal, it can run as one system — light, climate, shade, security, media, water, gates, and the devices that were never smart to begin with. Nothing in a house is impossible for us; some of it is just not obvious yet.
- For designers & architects
- Full design or retrofit
- Local-first, no cloud lock-in
01 — What gets automated
Nine things a house
can do by itself.
Most automation stops at turning a light on. These are the ones people actually notice — and the ones that get asked for once they have seen them. Every one runs locally, on the hub, with the live data it needs.
The metro is already telling you when to leave
Leave only when you’ll catch it.
A sensor knows you’re home. The published timetable and live disruption feed know when the next train is. Walking time and the platform finish the maths. The result is a light at the entrance that says leave now, wait, or take the next one — not another app to check.
If the train is delayed, the light waits. If the next one is too tight, it tells you. If you’re not home, it doesn’t bother.
Metro
Traffic
Flights
Weather
Energy price
Swiggy / Zomato
Pet feeder
Delivery ETA
If it has an API, a feed, a sensor, or IR/RF, it’s usually a candidate. This is the layer most automation companies never reach.
More than lights
Small automations that feel like magic.
Each one is a live signal, a rule and a useful output. No dashboard required.
Food ETA display
Swiggy / Zomato ETA on a small kitchen display; porch light turns amber under five minutes.
Desk presence
Walk away from the computer: monitor off, desk light off, AC back. Walk back: everything returns.
Window open, AC off
A window sensor cuts the AC — no remote, no reminder, no wasted afternoon.
Rain before you notice
Rain feed or local sensor closes the awning and shades before the balcony gets wet.
Sunrise shades
Shades open at actual sunrise — a different time every day — or hold blackout if you’re still asleep.
Flight or traffic delay
Live travel time updates; the house tells you when to leave, not just what the traffic app says.
Cheap energy window
When the tariff drops, the house runs the dishwasher, water heater or EV charger — automatically.
Pet feeding
Feed the cat at 7:00 and 18:00, portion-controlled. Skip if already fed; ping you if the bowl is empty.
The difference
Other systems control devices. This one uses context.
Typical patterns, not a brand-by-brand audit. Ambient Form Studio is vendor-neutral and local-first.

Home Assistant
Most of the stack runs on Home Assistant. Open source, on a hub inside the home — local automations, local voice and local AI, with the cloud optional.
The brief
The best technology in a room is the technology you don’t see.
No visible boxes. No five-app chaos. No rented brain in a data centre. Just a home that responds — and interiors that stay exactly as designed.
01 — Every stage
Blank shell, renovation, or finished home.
Most automation firms only work at first fix. We start where you are: lead the whole interior, join drawings that already exist, or retrofit a finished home with almost no visible change.
01
Fresh plan · full design
Design it in from the start.
Empty shell, new build or a full redo. We can lead the interior — space planning, materials, lighting and joinery — with automation designed into the same drawings.
- Full interior design
- Lighting & joinery
- Device schedule & commissioning
02
Renovation
Join the drawings.
You already have a plan, a designer or a contractor. We plug into it, coordinate first fix, and keep the technology invisible.
- Work with your designer
- First-fix coordination
- Minimal visible change
03
Lived-in home
Change almost nothing.
The home is finished and you’d rather not open a wall. IR, RF, relays and battery sensors bring existing devices into one system — reversible and renter-friendly.
- No chasing walls
- Reversible & renter-safe
- Existing devices stay
One studio from concept to commissioning. The scope changes; the standard doesn’t. Not sure which stage you’re in? Send a floor plan and a photo — we’ll tell you.
The automation ladder
An app is level one.
A home is level three.
Most “smart homes” stop at remote control: an app that replaces a switch. The useful jump is when the house reacts to presence, light, time and context — without you opening anything.
Remote control with extra steps.
One app per brand. You still do the thinking. Fine as a start; not a system.
- One app per ecosystem
- Manual taps & remotes
- “Smart” only when you remember
Scenes and schedules.
One app, a few routines, sunrise and sunset. Less tapping — but the house still waits for a trigger.
- Morning / evening scenes
- Timers & sunrise/sunset
- Still mostly manual
The house reacts.
Presence, light, weather and context. You stop touching switches. The room does the work.
- Lights follow the person
- Monitor off when you leave the desk
- AC off when a window opens
- Awning in before the rain
Describe a new rule.
An agent on the hub can turn a plain-language request into a new automation — locally, without a ticket.
- Local voice + local AI
- You can edit or remove it
- No cloud account required
Doing it yourself
The DIY tax.
- Five apps that don’t talk to each other
- One brand owns the decision
- Cloud accounts, updates and lock-in
- The family can’t work it
- No one to call when a routine breaks
Ambient Form Studio
One layer. Any brand.
We allow anything. We’re not loyal to a brand — we make the brands work together.
- Zigbee, Wi-Fi, BLE, IR, RF, relays
- Matter, ESPHome, Home Assistant
- Existing devices stay where possible
- One interface, local hub, local automations
- Documented, supported, yours
In practice Desk presence → monitor off · room empty → lights off · window open → AC off · rain due → awning in · sunrise → shades open.
The market
How it works now.
What we offer. Why we’re better.
The short version: the three ways a Mumbai 3BHK gets automated, what each one costs, and where our layer fits. The full landscape and sources are at the bottom.
01 — How it works now
Premium installer
₹15–30 lakhCrestron / Lutron · 3BHK
- Best finish and bespoke keypads
- One dealer, one warranty
- Closed catalogue; the dealer holds the file
- 8–15% a year after year one
- KNX and Control4 start lower
Best if finish is everything and you want one firm to call.
DIY stack
₹1–2.4 lakhfor a 3BHK
- Lowest upfront cost
- Four to six apps
- You are the support desk
- No drawings, no commissioning
Best if you enjoy tinkering and want to start small.
Ambient Form
₹4.5–5.5 lakhfor a 3BHK
- One app for every room
- Works with the devices you already own
- Retrofit without opening walls
- No licence, no mandatory yearly fee
- You own the system and the file
Best if you want it to work, stay open and be yours.
Why us, in one line: the same rooms and scenes for about a third of a premium quote — without five apps, a dealer holding the file, or a subscription for every device.
02 — What we offer
One local hub, one app, any brand that speaks a protocol, and a retrofit that doesn’t open walls by default. Start at ₹2 lakh for lights and presence; a whole home from ₹5 lakh. The device schedule, network map and project file are handed over.

These are capex bands, not five-year costs. The premium column also carries an 8–15% annual contract; the DIY column carries subscriptions and your weekends. The calculator below adds both. At ₹5 lakh we sit at the Control4 floor — with an open system.
03 — Why we’re better
You pay for the room, not the brand.
A Basalte keypad is ₹35,000–90,000 before it is wired. Our whole-home layer starts at ₹5 lakh. The money goes to devices and design, not a licence.
One app, not five.
Lights, AC, shades, door and camera in one place, on a hub in the house. It works offline, and the family can use it without a manual.
You own it after handover.
No mandatory AMC, no dealer holding the file, no per-device cloud plan. If you sell the flat, the system goes with it.
The same scope, priced
3 bedrooms · 18 lighting circuits
A circuit is a switched lighting group, not a device. Two to four bedrooms plus living, dining, kitchen, balconies and passages usually lands between 14 and 24.

- Drawings, device schedule and the project file
- Optional support, not a mandatory AMC
Indicative only. The model assumes a 3BHK-scale scope, a mix of lighting, climate, shade, entry and media, and ₹1,800–3,000 per circuit for hardware. Premium running cost is 12% of capex a year; DIY is ₹24,000 a year of apps and replacements; ours is an optional 6% support plan. No GST. A walkthrough replaces every number.
02 — For designers & architects
A technology partner, not another trade.
You shouldn’t have to become an integrator to deliver a smart home. We join early, read your drawings, and carry automation from first sketch to final scene — so it disappears into your design. We think in plans and materials as much as protocols. If a client wants one studio to lead both the interior and the technology, we can do that too.
-
Concept-stage input Automation intent that fits the plan, the joinery and the lighting design — before services are fixed on site.
-
Drawings & schedules Device schedules, ceiling and wall coordination, power and network requirements your site team can build from.
-
Retrofit mapping What can be smartened without replacing it — and what genuinely needs new hardware. No rip-and-replace by default.
-
White-label delivery We can be invisible to your client, or stand beside you on site. Your relationship, drawings and credit stay yours.

03 — Capabilities
The systems we design.
One studio for the parts of a home that need to talk to each other — specified, integrated and tuned as one system instead of a pile of gadgets.
Lighting & scenes
Layer ambient, task and accent light. One tap for dinner, a film, or “away” — with the right dimming curve, not a harsh on-off click.
Climate
ACs, fans and sensors working together — room by room, schedule by schedule, and off when the last person leaves.
Security & access
Doorbell, cameras, locks and alerts in one view — with local AI captions that say what happened, not just that motion was detected.
Cinema & media
Projector, screen, soundbar and shades fall into place from one button — or one sentence — without four remotes on the coffee table.
Curtains, awnings & shade
Morning light without the alarm, blinds down before the afternoon glare, the awning in before monsoon rain.
Energy & monitoring
See what’s drawing power today, spot the AC left on in an empty room, and automate the offenders off.
Voice, without the cloud
A wake word and commands processed on the hub inside the house — not by a speaker company’s data centre.
Networks & dashboards
Wi-Fi that reaches the last bedroom, a rack a technician can service, and screens that make sense to the people using them.
Retrofit & legacy
ACs, awnings, projectors, curtains and audio brought into the system through IR, RF, relays and bridges. If it has a remote, it can usually join.
Battery health, device health and camera clip retention are handled quietly in the background.
04 — Made to measure
The small, specific things.
“Can it close the awning when the sun hits my desk?” Yes. “Can the shades open at sunrise, even though it’s a different time each day?” Yes. “Can I add a new rule after handover?” Yes — tell the local agent. These are examples, not a fixed menu.
Never work in glare again.
The awning closes when the sun hits the desk or the balcony heats up, and reopens when it moves. No remote, no getting up, no lost afternoon.
Wake up with the light.
Shades open at sunrise — a different time every day — or at a fixed time you choose. Blackout stays until you’re actually ready to get up.
Make up a new rule.
Describe it to the local AI agent in plain language and it can add the automation. No call-out. For the fiddly or physical bits, we’re still here.
Meet the local agentThese are starting points, not a catalogue. If you can describe it — the sun, a time, a sensor, a person, a phrase — it can usually be built. Fully custom, down to the individual room. The list is effectively endless.
05 — Retrofit
If it has a remote, it can join the system.
Most homes already have good hardware — it’s just not connected. We use IR, RF, relays, bridges and sensors to bring existing devices into the same system. No rip-and-replace. No second app. No new wall clutter.
“A rooftop awning with no app, no API and no position feedback — now closes before rain and reports its state.”

We start with what’s there. Replacement is a last resort, not the business model.
Reversible by design.
Most of the system needs no drilling: plug-in lighting, IR climate control, battery sensors, a camera on a shelf. Move-out is an afternoon, not a renovation.
Go further, earlier.
In-wall switches, motorised tracks, concealed sensors and a wall dashboard — specified before first fix, so nothing gets chased into a finished wall later.
06 — Spaces
What it looks like when it’s not showing off.
Six ordinary moments from a well-run home. The technology is in the layer behind them: light, shade, air, sound and the quiet certainty that the door is locked.
Automation, in motion
Morning → Evening → Cinema → Away.
This is the plan demo running: lights, AC, projector, awning and lock changing together. The interactive version is further down.

Live demo — Floor plan
Your floor plan, as a
control surface.
Tap a marker and the room responds — lights, AC, blinds, awning, projector, lock. The same plan can live on a wall tablet in the hallway, so the house is legible at a glance, not buried in a list of entities.
Live demo — Voice
Ask the house.
Five voice notes the assistant actually gave — short, literal and local. The samples, and the whole demo, live on the residential homes page.
08 — Local AI
Privacy is part of the specification.
High-end clients ask where their data goes. With Ambient Form Studio, the answer is simple: it stays in the house. Camera descriptions, voice recognition and the language model run on a hub inside the apartment — not on someone else’s server.
Cameras & mics
Events happen in the room
Your hub
Home Assistant + local vision, speech and language models
Your phone
Only what you need, when you need it
No round trip to a data centre
Visitor descriptions
A local vision model turns a blurry snapshot into “a courier in a blue jacket left a parcel” — and keeps the history on your hub.
Voice without ears
Wake word, speech-to-text and text-to-speech all run on the hardware in the house. No audio sent to a speaker company.
Keeps working
Lights, AC, locks and scenes keep running if the internet drops. Remote access and alerts need the internet; the house doesn’t.
Yours to audit
Open-source Home Assistant at the core. No black box, no mandatory cloud subscription to keep the basics alive.
Cloud-first
- Camera footage leaves your home
- Most controls stop when the internet does
- Per-camera cloud plans
- The vendor holds the keys
Ambient Form local
- Footage stays on your hub
- Automations keep running offline
- No mandatory cloud fee
- You hold the keys
After handover
You don’t need us for every new rule.
We can leave a local AI agent on the hub. Describe the automation in plain language — “when the afternoon sun hits the balcony, close the awning” — and it can add it to the system. No cloud account, no ticket, no waiting.
When something physical needs a visit — a motor, a lock, a sensor, a failed device — we’re still here for on-site troubleshooting, repair and recommissioning. The system is yours; we’re the backup.
Ask about handover
Local agent · example
On your hub
“When the afternoon sun hits the balcony, close the awning. Open it again at sunset.”
Ambient Form agent
“Done. I’ll close it when the balcony light stays strong for five minutes, and reopen at sunset. You can edit the rule any time.”
Streaming services like Spotify and Netflix still use the internet. We’re talking about control, cameras and voice — the parts that should never need a data centre.
09 — The proof
This isn’t a concept deck.
A live installation, not a render. Every automation on this page has been lived with.
It’s the stack running a real home today — 85 automations, 12 dashboards, 3 camera feeds and one app. Built, broken, fixed and lived with.
85Automations in daily use
12Dashboards on one hub
3Camera feeds, processed locally
1App to run it all
The numbers are from the live system — awnings, projectors and older audio, all running from one app.
10 — Process
From first drawing to final scene.
We work alongside your studio and your site team, not around them. The earlier we’re involved, the less visible the technology — and the fewer surprises at handover.

Questions
The things designers ask.
If yours isn’t here, send a message — we answer within one working day.
Do you work white-label?
Yes. We can produce drawings, schedules and client documentation under your studio’s name and stay invisible on site — or be introduced as your automation partner. Either way, the client relationship stays yours.
We already have an electrical or AV contractor. Can you work with them?
Yes — that’s usually the best setup. We define the automation scope and the interfaces, then coordinate with your contractor on power, network, ceiling and joinery requirements. We’re happy to work to their programme.
What do you need from us to quote?
A floor plan, a brief on how the client lives, any device list they already have, and a few site photos if available. If drawings aren’t ready, a rough plan and a 20-minute call is enough to start.
Can you automate devices the client already owns?
That’s our default. ACs, awnings, projectors, curtains, lamps and older audio can often be brought in through IR, RF, relays and bridges. We audit what’s there first and only recommend replacement when the existing device genuinely can’t be integrated.
Do you sell hardware?
We’re vendor-neutral. We can supply and commission, or specify for your vendor to supply. Hardware is billed at actuals with your approval, and we don’t design around a single brand’s catalogue.
How early should we involve you?
Concept or design development is ideal — that’s when power, network, ceiling and joinery decisions are still open. We can also retrofit at the end of a project; it just means a few more visible compromises.
How do you charge?
A fixed project fee based on scope, not hourly billing. The blueprint is a standalone deliverable; if we take the project through commissioning, that fee is credited. Studio partners get trade rates and priority slots. See engagement models.
What about privacy and data?
Camera, voice and automation data stay on a hub inside the home by default. There is no mandatory cloud subscription and no vendor access to the client’s footage unless they explicitly grant it for support. The full picture is in our privacy note.
Do you work outside Mumbai and Hong Kong?
We work worldwide from studios in Mumbai and Hong Kong. Projects elsewhere start with a video call, then a site visit or a local partner if the scope needs one. Travel and site supervision are quoted separately, and the quote says so before you commit.
What runs the system?
Most of it runs on Home Assistant on a hub inside the home — open source, local automations, local voice and local AI. The cloud is optional, not the foundation.
Can we visit a live project?
For serious enquiries, yes — subject to the client’s permission. We can also demonstrate the system and the app over a video call, which is usually faster.

01
₹15–30 lakh
3BHK
3BHK
The premium integrator.
The finished room: bespoke keypads, lighting scenes, AV, blinds and security from one catalogue, installed and warranted by a dealer. This is the benchmark for how a smart home should feel.
- What you get
- Design-led hardware, commissioning, a single warranty, a showroom and a name to call.
- Where it stops
- The programming is dealer-authored. Retrofit often means new wiring. A keypad can cost more than a phone. The annual contract is 8–15% of the project.
Names you’ll meet: Crestron, Lutron, Basalte, Savant. In Mumbai, Trescent Lifestyles has built a business on this model since 2006; the lowest band on its enquiry form is ₹25–50 lakh.
02
₹8–20 lakh
3BHK
3BHK
The KNX / Basalte integrator.
An open bus with a luxury surface. KNX is a real standard, not a proprietary one, and a good integrator can mix Basalte, ABB and CORE keypads in one project. That is a genuine advantage over Crestron and Control4.
- What you get
- A robust wired bus, wide device choice, and — if the ETS file is handed over — any KNX professional can service it later.
- Where it stops
- The bus still has to be wired. Basalte keypads run ₹35,000–90,000 each before installation. Programming needs ETS6 Professional (€1,000) and a certified programmer, and many homeowners never receive the project file.
Names you’ll meet: Basalte, ABB, CORE, Gira, Jung, MDT, Theben; KNX-certified integrators in Mumbai and Pune.
03
₹5–10 lakh
3BHK
3BHK
The curated system at our price.
Control4 is a dealer-installed system with a curated catalogue. AHA Smart Homes publishes a ₹5 lakh complete-3BHK benchmark from two Mumbai experience centres. If you want one brand, one showroom and one warranty at our price, this is the honest alternative.
- What you get
- A single product line, a showroom, a known integration path and a dealer on the phone.
- Where it stops
- You are inside one catalogue. Adding a device outside it means a dealer visit and dealer-only Composer Pro programming. The ₹5 lakh is a benchmark, not a quote, and the scope is fixed to the package.
Names you’ll meet: Control4, AHA Smart Homes; builder packages that arrive with the flat and end at handover.
04
₹1–2.4 lakh
3BHK
3BHK
The DIY stack.
Aqara sensors, a couple of smart switches, an IR blaster, a Hue bridge and the app that came with each. Cheap to start, genuinely useful in a rental, and entirely yours — until something stops working.
- What you get
- Low entry cost, incremental purchases, no dealer, no contract, no wall chasing.
- Where it stops
- Four to six apps. Cloud accounts, including Hue’s mandatory account since 2023. Automations only as good as the time you put in. When a routine breaks at 11pm, you are the support desk.
Names you’ll meet: Aqara, Xiaomi, Philips Hue, Wiz, SwitchBot, Apple Home, Google Home, Alexa — and a different app for each.

Ambient Form: the open layer at the price of a curated one.
One layer over whatever hardware is already there. Not a catalogue and not a single app: a local hub that speaks the protocols, one interface, and a studio that designs the interior and the automation together. At ₹5 lakh we are 37–75% below the published KNX band and 67–83% below Crestron, without giving up the functions that matter.
- What you get
- Any brand that speaks a protocol, retrofit without opening walls by default, one app, local control, documentation, and the system in your name.
- Where it stops
- We are not a bespoke keypad manufacturer and not the right firm for a 10,000 sq ft villa with a plant room. We say so below.
What we don’t sell: a brand, a licence, a five-year lock-in, or a showroom you pay for.

How the ranges were built. Crestron, KNX and Control4 bands are published
2026 India trade ranges, cross-checked against hardware list prices. Basalte
keypad pricing is from a 2026 India installer comparison. The AMC band is the
range published by Indian service firms. The DIY band is the sum of typical Indian
retail prices for a 3BHK, not a quote. Trescent’s ₹25–50 lakh floor is the lowest
band on its own enquiry form, read on 6 November 2026. AHA’s ₹5 lakh 3BHK is a
published benchmark, not a quote. Our own figures are the launch prices on the
studio site. Dealer margin is not published anywhere we could verify, so the
brand/tools slice is a modelled allowance, not a claim about any firm. Nothing here
is a valuation of a competitor, and no competitor’s non-public price is used.
Figures are indicative, not a quote. A firm is named only where it has published a price.
