Smart meeting room displays.
No enterprise nonsense.

Lobby connects to your Google Calendar or Microsoft 365 calendar and shows real-time room availability — on purpose-built e-ink hardware, in any browser tab, or on a single overview screen for the whole office. Setup takes 10 minutes & the price won’t need a budget meeting.

Sound familiar?

Your meeting rooms are a mess. Not because of the people. Because of the process.

Two teams, one room.

Someone books a room in Google Calendar. Someone else walks in anyway. No one wins. The meeting doesn’t start on time. Everyone’s annoyed.

Booked. Empty. Locked.

The room shows as taken for an hour. But nobody’s there. The meeting was cancelled at 7am and nobody updated the calendar. That room was wasted.

Is this room free? Who knows.

You walk up to a meeting room. You’re not sure if it’s available. You knock. You check your phone. You find another room. This is not what your team’s time is for.

Meet Lobby

Everything your team needs to know about the room. On the wall outside it.

Lobby is an e-ink meeting room display that pulls live data directly from your Google Calendar or Microsoft 365 calendar. It shows room name, current status, who has it, and what’s next — all on a crisp, paper-like screen that’s readable from across the corridor.

No new booking app. No training. No IT project. If your team already uses Google Calendar or Microsoft 365 for meetings, Lobby just works. The display hardware is TRMNL — an open-source e-ink device you buy once and own outright.

Hardware

Simple by design

Live in 3 steps.

01

Connect your calendar

Sign in with your Google Workspace or Microsoft 365 account. Authorise Lobby to read your room resources. Done.

02

Mount the display

Stick the magnetic mount next to your meeting room door. Hang the Lobby display. It connects to your WiFi and starts syncing immediately.

03

Walk in. Or walk past.

The display shows real-time availability. Green = free. The current meeting, the next meeting. That’s it.

Three ways to display

Physical, virtual, or an overview of the lot.

Same calendar sync, same dashboard, same pricing. Pick the surface that fits your space — or mix them.

Physical

Physical e-ink

Beside every meeting room door. Battery-powered TRMNL hardware. No glare, readable from 5 metres, charges once a year.

How the e-ink display works
Virtual

Virtual display

Same view, in a browser tab on any tablet, TV, or screen you already own. No hardware to ship, no mount, no pairing code — just open a URL.

How virtual displays work
Overview

Room overview

See every room at a glance, on a single screen. Perfect for lobbies and shared areas. Runs on e-ink or in a browser. Counts as one display.

How the overview works

Built for how real offices work.

Google Calendar and Microsoft 365 native

Pulls directly from your existing room resources in Google Workspace or Microsoft 365 — sign in with whichever you use. No duplicate system, no new calendar to manage. Bookings show on the display within seconds.

E-ink display — powered by TRMNL

Paper-like screen. No glare. Readable from 5 metres. Beautiful in any lighting. Built on TRMNL open-source hardware — you own the device outright. Consumes zero power when static.

Virtual display on any screen

Same room view, in a browser tab. Runs on any tablet, TV, or screen you already own. No shipping, no mount, no pairing — just a URL.

Room overview display

Every room, on one screen. Pick which rooms to include and point any browser or e-ink screen at the URL. Designed for lobbies, kitchens, and reception TVs.

Up to 12 months battery

No cable drilling. No power supply headaches. Magnetic wall mount. Charge once a year (or less). Just works.

Instant room status

Big, clear, colour-coded status: green for available, red for occupied. Visible from the corridor before you even walk up to the door.

Self-serve setup

No IT team required. No professional installation. No support ticket. A founder or office manager can set up an entire office in under an hour.

Honest pricing

Monthly or Yearly, you decide. One low fee for up to 100 screens. Cancel any time. No “contact sales” nonsense.

Teams who stopped the room chaos.

We had a 10-person office and others wanted $3,000 to get us started. Lobby cost us less than a desk lamp and it works perfectly.
