The operating system for your building
One web portal for everything a building runs: the BMS, access, hospitality, residents, services, EV charging and users. Every module looks and works the same way, starts from the numbers that matter today, and works on a phone.

Monitor and control the building's infrastructure
Access activity, work time and door status
Reservations, rooms and guest services
Residential units, residents and their services
Guest services, room service and activity bookings
Charging stations, sessions and analytics
Building users, roles and permissions
One building, every system on one screen
The base of PIERRE OS. Lighting, HVAC, energy, consumption, shading, environment and security, live, with whatever needs attention first.
Every system at a glance
- Total, online and offline devices with a seven-day trend
- Indoor climate, power, energy and water as live tiles
- A card per system with its device count, one tap to its devices

Device lists
Every device, problems first: online, offline and not reporting, grouped by building part and controller.
Logs
What happened and what is still broken: connection problems, alerts and changes, grouped by day.
Device pages
Every thermostat, door, light, meter or charger with its live reading, settings and who can use it.
Controllers
Connection, uptime, firmware and wiring of every controller at a glance.
All systems, one layout
Lighting, energy, consumption, shading, environment and security each get the same dashboard, list, logs and analytics.
Thousands of devices
Lists built for buildings with nearly eight thousand devices, with filters by status, source and type.
Who is inside, right now
Every door, reader and app unlock of the building in one place, live and on the building's own clock.
Every door with its readers
- Locked state, readers and today's opens for every door
- Entry and exit readers and app unlocks, door by door
- A reader that has gone silent is flagged right away

Live dashboard
Inside now, opens today and the busiest reader as live tiles, with a link to share.
Work time
First entry to last exit per person on a 24-hour track, from real exit taps, never estimated.
Activity log
Every reader tap and app unlock, searchable by person, door and time.
Run the hotel from one screen
Front desk, rooms, rates, guests, messaging, online booking, payments and housekeeping, connected to the rooms' own doors and climate.
Rooms you can sell, rooms to clean
- Ready to sell, free but not yet cleaned, occupied and out of order at a glance
- One filter bar for floor, type, status and housekeeping, as a list or by floor
- Link each room to its door and climate devices from the BMS

Front desk
The day's exceptions first: arrivals without a room, overdue check-outs, rooms still to clean.
Calendar
Stays without a room wait in a tray: drag them onto a room, or let the desk assign them by type.
Guests
One profile per guest with stays, documents and preferences, with export and anonymisation built in.
Messaging
Booking.com, Airbnb and Expedia conversations next to the stay they belong to.
Booking widget
Your own booking engine on your website, with a live preview as you set it up.
Payments
Payment links and card payments through the gateways offered in your country.
Housekeeping
A board from dirty to clean, with staff, assignments and priorities, and an app for the housekeepers.
Charging that knows the building
Charging stations, sessions and energy in one view, with the grid, solar and the building's other loads in the same diagram.
Grid, solar and chargers in one diagram
- Charger state and readings straight from the chargers (OCPP)
- Energy groups, history, sources and analytics, one page each
- An energy balancer through the PIERRE gateway is on its way

For the people who live and stay there
PIERRE OS also serves the residents and guests of the building, not only the people who run it.
Resident Portal
Residential units, residents and their services in one place.
Services & Orders
Guest services, room service and activity bookings, ordered and followed through.
The right access for everyone
Users, roles and permissions per module, and an overview of every building for operators.
Users
PIERRE app users and portal users in one list, with their roles and access devices.
Portal roles
What each role can do in each module, and who holds it.
Administration
Every building, partner and module, sorted by what needs attention.
Audit log
Who did what and when, across the whole portal.
Every page works the same way
Learn one module and you know them all.
Today first
A short title and one line with the numbers that matter today.
Tiles that filter
Tiles count what needs attention; each opens the list already filtered.
Chips and views
One filter bar, counted chips and views of the same data: board, list, floors, calendar.
Clear panels
Facts as key and value rows, actions right where you need them.
Phone first
Every page works on a phone: tiles stack, lists scroll, dialogs become sheets.
Real data
Every number comes from the building's own live data.
