Kumbhavanam: Automating my dad's homestay with AI

The Kumbhavanam home page: the heading A whole home for your family, 4 km from Chennai airport, over a dim photo of the hall, with Call to book and WhatsApp us buttons — The home page, the street map on the location page, and the booking steps.

The Kumbhavanam location page: a dark green street map titled Our gate and what is around it, with numbered places joined to the gate by dotted lines — The home page, the street map on the location page, and the booking steps.

The stay

Kumbhavanam Home Stay is my dad's homestay: a fully furnished 3BHK flat in Adambakkam, Chennai, about 4 km from the airport. It sleeps up to 9, with its own kitchen, AC in every bedroom and the hall, and covered parking.

My dad runs it, and he isn't a technical person. Anything I built had to make his day simpler, not give him one more thing to learn.

What it needed

Before this, the stay ran like most small homestays do. Here's what changed:

Before

One Wi-Fi password for every guest. Anyone who had ever stayed could still connect.
Door access sorted by hand for each guest.
No website of its own to answer guests' questions before they book.

Now

Each booking gets its own Wi-Fi password, gone at check-out.
Each booking gets its own door code, set up from a phone at check-in.
A website made for search, with the answers guests look for.

All of it had to stay simple enough for my dad and the helper who meets the guests.

What I built

A brand to build on

The symbol is a Purna Kumbham, the welcome pot, in gold on forest green. Its two mango leaves are my parents, Kumar and Bhavani, and the bud between them is the garden (vanam) that grows from them. It echoes the gold pot on the green wall of the building, and the name comes in English and Tamil.

A few pieces of the kit: the logos, the welcome card, the Wi-Fi card, the table standee and a social post.

The kit has everything a small business hands out or posts:

Logos in four colour versions, for dark and light backgrounds and one-colour print.
Stationery: visiting cards, a letterhead, an invoice, an envelope and an email signature.
Guest prints: a welcome card with the house rules, a Wi-Fi card, a thank-you card, and a table standee with QR codes to leave a Google review or book direct next time.
Social: posts, stories, Google and Facebook covers, and festival posts for the year ahead.
A round stamp and a 12-page brand guide that says which logo goes where.

The website takes its logos and icons straight from the kit when it builds, so the two never drift apart.

A homestay website that answers guests' questions

The Kumbhavanam home page on a laptop and on a phone — The home page leads with the facts a family wants first: how far the airport is, how many it sleeps, and how to book.

The Kumbhavanam home page on a laptop and on a phone, on a phone — The home page leads with the facts a family wants first: how far the airport is, how many it sleeps, and how to book.

The site opens on the stay itself: the whole flat, what's included, how to book, and an enquiry form. On a phone, Call and WhatsApp buttons stay at the bottom of every page. Each room has its own page with its photos, and the FAQ answers 18 questions, each in a clear first sentence.

The Bedroom 1 page on a phone: the heading Bedroom 1, a master bedroom with a queen bed, above its photos, with Call and WhatsApp buttons at the bottom — The home page, a room page and the booking steps on a phone.

SEO from the first day

A homestay lives or dies by search, so the site was built for it from the start:

A page for each search. I picked the phrases people type, such as "homestay near Chennai airport", "stay near MIOT hospital" and "rooms for wedding guests Adambakkam", and gave each one a page that answers it.
Real distances. The location page has a street map of the gate and what's around it, with distances by road to the airport, hospitals and wedding halls.
Checked titles. Every page has its own title and description, and the build fails if one is missing or too long.
Structured data. Each page tells search engines what it is: the stay, each room, the FAQ, the address and the spot on the map.
A name Google gets wrong. Google changes "Kumbhavanam" to "Kumbakonam", so the titles, the first line of the home page and the structured data always say "Kumbhavanam Home Stay" and "Adambakkam" together.
Open to AI assistants. Search and AI crawlers are welcome, and an llms.txt file gives AI tools the key facts: the beds, the rooms and the distances.

The location page's street map: dark green roads with numbered places, each joined to the gate by a dotted line — The street map on the location page. Each number is a place nearby, with its distance by road.

Automated check-in with smart locks

For the guest, booking is three steps: call with your dates, share an ID, and get your door code.

The How to book section: three steps, Call with your dates, Share ID proof and Get your door code, above the enquiry form — What the guest sees. The third step is where the check-in system comes in.

Behind that third step is the check-in system I built. It only works inside the house, never on the open internet, because it can create door codes. The helper who meets the guest does the whole check-in from a phone:

A check-in, step by step

Scan the ID
The helper scans the guest's Aadhaar QR code or passport with the phone camera, and the form fills itself. Only the last 4 digits of the ID number are kept.
Pick the rooms and dates
The whole flat or any of the rooms, with the check-in and check-out time.
Check in
The system makes one door code for every door that booking needs, and one Wi-Fi password, both valid only for the stay.
Send the codes
One tap opens WhatsApp with the door code and Wi-Fi password ready to send to the guest.
Check-outAutomatic
When the stay ends, the code and the password stop working and are removed.

Try it with a made-up guest:

Rooms

Nights

A made-up guest. The codes are random and open nothing.

What that means day to day:

Every booking gets its own codes. Past guests can't get back in, or back online.
Longer stays keep the same codes. Adding a night only moves the end time.
One booking never cuts off another. The guest Wi-Fi is one network with a separate password for each booking.
Nothing to remember at check-out. Codes and passwords go when the stay ends, or straight away if the guest leaves early.
My dad doesn't have to be there. The helper checks guests in from a phone.

Built with AI and Claude Code in about a week

I built all of this in about a week, working with Claude Code, an AI coding tool:

The brand kit: the symbol, the logos, the prints, the social posts and the brand guide.
The website, starting from the same setup as this site, with checks that run on every change and speed tests before every release.
The SEO: the search phrases, the structured data, the sitemap and llms.txt.
The hosting on AWS, set up as code, with the same release flow I use here.
The check-in system, from testing door codes and Wi-Fi passwords on the real locks and network to the app the helper uses.

AI wrote the code with me. My part was deciding what to build, what to leave out and what had to stay safe, then testing it on the real doors and Wi-Fi.

What it gave my dad

My dad isn't a technical person. This has helped him understand his business better and given him more control over it, while the routine work runs on its own.

Where it is now

The website is live at kumbhavanam.com, and the helper checks guests in with the system.
