Walter BalducciCommunications ManagerAutomatic Nuki door codes and a building door that opens for guests.
MessageMind’s AI agent connects to Nuki, creates a keypad code for each stay and sends it in the guest’s Airbnb or Booking.com thread or on WhatsApp. With Nuki Opener it buzzes guests through the building door, and it answers late arrivals and flags low batteries.

01Keypad codes
Every booking gets its own six-digit Nuki code.
City flats in Vienna, Berlin and London fill from Airbnb, Booking.com and direct bookings. The AI agent creates a Nuki Keypad code for each booking, valid for its dates and hours, and sends it with your arrival steps in the guest’s Airbnb or Booking.com thread, or on WhatsApp when they booked direct.
- A six-digit code for every booking
- Inside each Airbnb or Booking.com conversation
- Direct guests get it on WhatsApp or email
02Building door
At the intercom at midnight? Nuki Opener lets them in.
A guest reaches a Berlin building late and the heavy street door is shut. The AI agent answers in seconds, checks the booking and, once the guest says they are at the entrance, buzzes the door open through Nuki Opener, then sends the keypad code for the flat upstairs.
- Street door buzzed open through the Opener
- The flat’s keypad code right after
- Answered at any hour, in their language
03Check-in times
A late checkout agreed? The Nuki code stays a little longer.
Each code runs from check-in to checkout, set by date and hour in Nuki. When you approve an early arrival or a late checkout, the AI agent moves the code’s window to match and tells the guest, and once they have gone, the code is deleted and your cleaner hears the flat is free.
- Valid by date and by hour
- Stretched for early arrivals or late checkouts
- Deleted once the guest checks out
What you can automate with Nuki.
AI for Nuki hosts covers both doors a city guest meets: the building entrance on the intercom and the flat on the keypad, from the first code to the last alert.
Gives each stay its keypad code
- Creates a six-digit Nuki Keypad code for every booking, valid by date and hour.
- Sends a Nuki weblink that opens the door from the guest’s phone during their stay.
- Shares a Nuki app invite with guests who want a phone key as well as a code.
Opens the building door
- Buzzes guests through the street door with Nuki Opener once they reach the entrance.
- Sends the intercom steps and the flat code together, so one message covers both doors.
Keeps codes in step with bookings
- Stretches or shortens a code’s window when an early arrival or late checkout is agreed.
- Deletes the code from Nuki when a booking is cancelled or the guest checks out.
Looks after guests on arrival
- Unlocks the flat remotely for a guest locked outside, after confirming the booking is theirs.
- Sends your welcome when the activity log first shows the guest’s code at the door.
Opens up for your team
- Gives cleaners a code that works on their weekdays and hours.
- Creates a code for a repair visit that opens the door during its booked slot.
Keeps watch between stays
- Locks the door from afar when Nuki reports it was left unlocked.
- Tells your team when the expected arrival time passes with no sign of the guest.
- Warns your team about low batteries and doors the Door Sensor shows open.

Buzz Booking.com guests through the building door with Nuki Opener
A Booking.com guest writes that they are outside the building at 11pm. The AI agent checks the reservation, buzzes the street door through Nuki Opener and replies in the Booking.com chat with the floor, the flat number and the keypad code, so the whole arrival fits in one message.
Customer: We’re outside the building, which bell do we press?
AI agent: Push the door, I’ve just opened it for you! Flat 7 is on the third floor, and your code is in this chat.
-
Check on a Nuki guest whose code is still unused at 9pm
The guest planned to arrive at 6pm, and by 9pm their code has stayed unused. The AI agent messages them to check all is well, repeats the arrival steps and tells your team, while the code and the Opener stay ready.
Customer: Sorry, our flight was delayed! Landing at midnight now.
AI agent: Thanks for letting me know! Your code works whenever you arrive, and I’ll buzz the street door when you message me from outside.
-
Send a Nuki weblink to guests who would rather use their phone
A guest who finds keypads fiddly asks whether the door can open from their phone. The AI agent sends a Nuki weblink valid for their dates, which opens the flat and, with Nuki Opener, the building door too, and the link closes by itself at checkout.
-
Lock the flat from afar when the Door Sensor shows it unlocked
An hour after a guest heads out for dinner, the Door Sensor shows the door closed but the lock still open. The AI agent locks it from afar, lets the guest know in their thread and leaves your team a note in case it happens again.
Advanced Nuki automations.
Nuki codes and the Opener join your PMS, CRM, payments and phone line, so every city guest gets through both doors without waiting for a key.

Turn a university enquiry into an Odoo quote, Stripe payment and Nuki code
- A university’s guest office emails about a flat for a visiting researcher’s two-month stay.
- The AI agent checks Smoobu for free dates and replies with the monthly price and flat details.
- Odoo gets the university as a customer, with a quotation the guest office accepts online.
- A Stripe payment link settles the quotation, and the stay is booked in Smoobu.
- On arrival morning the researcher gets the Nuki code and the intercom steps by email.
-
Buzz a Booking.com guest in by phone with Nuki Opener
- A Booking.com guest reaches the building at 1am and rings your number from the pavement.
- The AI agent picks up, finds the reservation and checks the caller’s name against it.
- Nuki Opener buzzes the street door open while the guest is still on the line.
- Upstairs, the keypad code already waiting in their Booking.com chat opens the flat.
- A short summary of the call sits in the guest’s thread for your morning team.
-
Let early Lodgify guests drop their bags with a short Nuki code
- A Lodgify guest lands at 9am and asks on WhatsApp whether they can leave their cases.
- The AI agent checks with your cleaner that the flat is ready for a quick bag drop.
- Once the cleaner says yes, the guest gets a Nuki code that works for half an hour.
- Nuki Opener buzzes them through the building door when they arrive with their bags.
- Their stay code follows at 3pm, and your team sees the bag drop in the same thread.
Made for flats behind a street door.
From one Altbau flat in Vienna to twenty apartments across Berlin, the AI agent looks after the building door, the flat door and every question in between.
-
One arrival message for every channel
Airbnb, Booking.com and direct guests each get the code and the intercom steps, posted where their booking lives.

Buzzer, lift and luggage questions

-
Every flat in your house style
Each apartment keeps its own doors, intercom steps and welcome, and every message reads like your team wrote it.

A real person for the tricky ones
A broken lift or a noise complaint from the neighbours goes to the right teammate, with the booking and the chat attached.

Nuki Airbnb integration: questions and answers
Does Nuki work with Airbnb and Booking.com?
Yes. Once your Nuki account is linked to MessageMind, the AI agent creates a keypad code for every Airbnb and Booking.com booking and posts it in that guest’s thread with your arrival steps. With Nuki Opener on the intercom, it opens the building door for them too.
Can AI send door codes to guests automatically?
Yes. Each booking gets a fresh code for its own dates and hours, sent at the time you choose, and the AI agent answers the questions that follow. Your team sees which code belongs to which guest, and nobody copies codes between apps.
How does Nuki Opener let guests into the building?
Nuki Opener connects to the intercom in your flat. When a guest says they are at the entrance, the AI agent checks the booking and buzzes the street door open, and a weblink sent for their stay can open it too, from check-in to checkout.
Can guests use WhatsApp or their phone instead of a code?
Yes. Direct guests can get their code on WhatsApp, SMS or email, and any guest can have a Nuki weblink, valid for the stay, that opens the door from their phone. Airbnb and Booking.com guests get the same help inside their booking thread.
Can a door code stretch for a late checkout?
Yes. When you approve the new time, the AI agent shifts the code’s window in Nuki and lets the guest know. A cancelled booking has its code deleted straight away, so the flat is ready for whoever comes next.
Do Nuki locks need Wi-Fi or a Bridge?
Nuki locks with built-in Wi-Fi go online on their own, and other models connect through a Nuki Bridge. Online, the AI agent creates and changes codes from anywhere, opens the door for a locked-out guest and hears about batteries and the Door Sensor as things happen.
Can cleaners have their own door codes?
Yes. Cleaners can have a Nuki code that works on their weekdays and hours, kept apart from guest codes, and a repair visit gets a code for its slot. The activity log names each code, so every entry has a person attached.
What if a guest arrives much later than planned?
When the expected time passes and their code is still unused, the AI agent checks in with the guest and lets your team know. Whenever they do reach the door, the code is ready, and Nuki Opener can buzz them into the building at 3am.
When do the first door codes go out?
On the day you pick. Our team connects your Nuki account, Keypads and Opener with you, adds your booking channels and writes the arrival steps for each building, and guests install nothing.
How much does a Nuki AI agent cost?
You pay for the MessageMind plan that suits you, with its own channels, monthly credits and team seats, and our pricing page sets the plans out side by side. Our team can help you choose one for the number of flats and Nuki locks you run.
Two doors, one message, and every guest inside.
The street door buzzes open, the keypad code works on time and the flat is ready for every guest.
