Going fobless is easy—here's how it works
Three steps, then you never think about the buzzer again.
Get your number
We provision a dedicated local number for your building's intercom to dial. Nothing to install.
Email your building
Send your property manager the new number to put on the intercom for your unit. Otto gives you a pre-written note — so it's one email, and one change.
Set your rules, and Otto answers
Arm it with a tap, a timer, a schedule, or "Hey Siri." Then Otto answers the buzz and plays the release tone — no call to pick up, nothing for your guest to download.
A peek inside the app
Everything runs from one simple screen on your phone — nothing for your guests to download.
One plan. Every feature.
No picking and choosing what you need. Everything a home needs is in the one plan.
Short-term rentals, on autopilot.
Host on Airbnb or Vrbo? Pro turns every check-in into something you never touch. Connect your calendar once — the door handles the rest, so you can truly set it and forget it.
Every booking, handled for you
Connect your Airbnb or Vrbo (beta) calendar and each reservation gets its own guest link — live from check-in, armed around your guest's arrival, and expired at checkout. No messages to send, no codes to rotate, no late-night "how do I get in?"
Your own guest page
Put one branded link — your-place.ottobuzzer.com — in your listing and check-in message, and never send another. Each guest just enters the last 4 digits of the phone they booked with, and they're in. No custom link per stay; guest names, early check-in approvals, and a full entry log are handled for you.
Smart locks, secured end to end
Not just buzzer buildings. Through Home Assistant or SmartThings, Pro hands out virtual keys to your smart door locks — issued per stay, revoked at checkout, and encrypted end-to-end. Put more than one door on the same guest link, so an arrival that needs the building entrance and the suite gets both, each named so your guest knows which is which.
Every guest goes to your own address — your-place.ottobuzzer.com — and lets themselves in with the last 4 digits of the phone they booked with.

Questions
What do I get for $5/month?
Everything a resident needs, at one flat price — no picking and choosing. A dedicated number, automatic door release, multiple call-forward numbers, activation timers, access schedules, virtual fobs and guest links, caller-ID filtering, email and push alerts, and smart-home control from Siri Shortcuts or Home Assistant. Cancel anytime.
Do guests need to download an app?
No. Guests just buzz your existing intercom like they always have — Otto answers on your side.
Where is Otto available?
The US and Canada, for now — we provision local US and Canadian numbers. More regions are on the way.
I run a short-term rental — what does Pro add?
Pro connects your Airbnb or Vrbo (beta) calendar and automates the whole check-in. You get a branded guest page at your-place.ottobuzzer.com — send that one link once and every guest lets themselves in with the last 4 digits of the phone they booked with, no custom link per stay. Behind the scenes, each reservation auto-arms around arrival and expires at checkout, guest names fill in from your booking emails, early check-ins are a one-tap approve, and every entry is logged. It's $12/month per property as an introductory rate — the price is heading to $15, but sign up now and you lock in $12 for as long as you stay subscribed.
Can it manage my smart lock, not just a buzzer?
Yes — with Home Assistant, Pro issues virtual keys to your smart door locks, per stay, revoked at checkout and secured end-to-end. So properties without a buzzer work too, and you manage every door from one place.
What happens if I forget to activate it?
The call forwards to your phone, just like today. Nothing breaks; the door just doesn't open automatically.
Do I need to install any hardware?
No. Otto works with your building's existing intercom over the phone line — there's nothing to wire up.
