Home / Platform / BMS and Adam

One BMS for the whole building, and every building you run

Heating plant, ventilation, rooms, lighting, access, meters and alarms in one cloud-native BMS at bisly.cloud, for one building or the whole portfolio, in any browser. Adam, the built-in AI assistant, watches every datapoint and tells your team what needs attention, in plain language.

Who works in the BMS, and what for

Each person gets the view and the rights their job needs. Access is per user and every action is logged with user and time.

Facility manager

Runs the building day to day: changes setpoints and schedules, answers alarms, finds the room behind a complaint, sets a unit to manual for maintenance and back to Auto afterwards.

Owner and asset manager

Compares energy, indoor air and open alarms per m² across buildings, and gets monthly energy and indoor-air reports as PDF, CSV or Excel without asking anyone for them.

Service partner

The certified partner who delivered the building services it in the same platform: sees the same live picture, fixes most faults remotely, and drives out only when hands are needed.

Tenants and residents

Adjust their own rooms within the limits the manager sets, on the Bisly Hub, the room controller or in the Bisly app, and see their own consumption from the first day of the tenancy.

Every screen, and what it is for

The modules follow the Building Management menu. Pick one for the screen and the goal behind it. Screens use sample data.

Devices. Every installed device with its status, type, unit and address, so a silent sensor shows up before a tenant calls. Sample data; names changed.

Adam finds the fault and tells you what to do

Adam is the AI assistant built into the Bisly BMS. Ask it a question in plain language ("Why is meeting room 3.14 cold?") and it reads the building's live data, trends and history to answer, propose a fix or carry out the command.

Sample conversation

Why is meeting room 3.14 cold?

The radiator valve in 3.14 has been fully open for 6 hours, but the room has stayed at 18.9 °C. Heating circuit 2 is delivering normal flow temperature to the other rooms on the floor, so the valve actuator is most likely stuck. I have flagged it to your service partner. Until it is fixed, I can raise the setpoint in 3.12 next door so the meeting can move there.

Do that, and tell the facility manager.

Done. 3.12 is heating to 21.5 °C and will be ready in about 40 minutes. The facility manager has been notified by e-mail.

Fault detection

Flags sensor drift, stuck actuators, short cycling and abnormal delta-T, with a building health score.

Anomaly detection

Catches rooms that miss their setpoint, open windows losing heat, consumption spikes and subsystems working against each other.

Acceptance and health tests

Runs the site acceptance test at handover and periodic state-of-health tests, with a report for the manager.

Energy optimiser

Reads day-ahead electricity prices and shifts setpoints inside comfort limits: pre-heating and pre-cooling when energy is cheap, with demand-response and VPP interfaces.

Data you can go back to

Every datapoint is logged and kept, so a complaint, a bill or an audit always has the trend behind it.

What the EPBD asks of a BMS, and where it is in Bisly

Building automation required under the EPBD has to do more than switch plant on and off. These functions are standard in every Bisly BMS.

Requirement	Where it is in the Bisly BMS
Continuous monitoring	Every datapoint live in Overview, Equipment and Rooms, with alarms on any threshold
Logging and analysis	Trends kept up to 5 years, overlay and year-on-year comparison
Benchmarking	Energy and indoor air per m², compared month on month and across buildings
Detecting losses of efficiency	Adam's fault and anomaly detection, with the responsible person informed
Interoperability	Modbus, M-Bus, DALI-2, KNX via a KNX/IP gateway, and a documented REST API

How Bisly meets EN ISO 52120-1

EN ISO 52120-1 sets out what building automation must do for each efficiency class. This is where each capability sits in Bisly.

Capability	How Bisly meets it
Continuous energy monitoring	M-Bus and Modbus meters on heating, cooling, ventilation, lighting and submeters
Energy analysis and trends	Live dashboards in bisly.cloud, with CSV and API export
Building energy KPIs	kWh per m² a year, weather-normalised, plus COP, SFP and W/m² per system
Demand-based HVAC and lighting	Occupancy, CO₂, daylight and schedule per room and zone
Fault detection and alarms	Alarms on I/O points and Modbus registers, SMS and e-mail by severity, with an audit trail
Fault diagnostics	Automatic diagnosis reported to the facility manager
Functional testing at handover	Test protocols and handover documents from bisly.cloud
Energy efficiency class	Efficiency-class dashboard against the energy budget

Class B functions as standard, class A where you need it.

One platform for every building system

Every technical system on one platform

HVAC and air handling, heating plant, room climate, DALI-2 lighting and shading, access control, intercoms and cameras, lifts, fire panel, pumps, de-icing, leak detection and metering: one BMS, one alarm list, one login. Bisly supervises the plant's existing controllers.

BACS platform

A network of its own

The automation runs on a dedicated LAN behind a pre-configured Bisly router, physically separate from tenant and office IT. One uplink per panel, no riser or floor switches; topology, port status and device health are visible in the BMS.

Site networking

Run and supported from anywhere

Your facility team and your certified partner work on the building remotely, backed by Bisly support; most issues are solved without a site visit. The site talks to the cloud over outbound HTTPS only, and control keeps running locally in the controllers through an outage.

Remote access

Open to other systems

Modbus client for the plant, M-Bus for meters, DALI-2 for lighting, OSDP, SIP and ONVIF for access, intercoms and cameras; a documented REST API with role-based tokens.

Integrations

Built to run one building or hundreds

The Bisly BMS gives operators, facility managers and service partners one place to monitor, control and optimise non-residential buildings, with real-time data, long-term trends, energy optimisation and health checks behind it.

One environment

Every building system managed in a single environment.

Regulation-ready

Operation to EN ISO 52120-1 and to public-owner requirements such as those of Riigi Kinnisvara (RKAS), Estonia's state real-estate company.

Energy optimisation

Control that follows the day-ahead electricity price, inside comfort limits.

Portfolio oversight

Multi-building management, compared per m² across the portfolio.

Open to other systems

Modbus, the REST API and third-party integrations, with support.

AI-ready

Adam, the AI assistant, built in, on a platform ready for machine learning.

Built to be trusted with a building

Questions we get on the BMS

We already have a BMS. Do we have to replace it?

No. Bisly connects to existing head-ends over open protocols and APIs and automates the rest of the building, so you can modernise floor by floor and building by building.

Where is our data, and who can see it?

In Microsoft Azure, behind Cloudflare. The owner decides who has access; rights are per user, managers operate and administrators configure, and every action is logged.

What happens if the internet goes down?

Nothing in the rooms changes. The Bisly server in the building keeps running the last schedules and setpoints, and the BMS fills in the gap when the connection returns.

Is there a mobile app?

Yes, for tenants and residents: their own rooms and consumption in the Bisly app. The maintenance team gets alarms by SMS and e-mail, and overrides and status in the BMS, which works in any phone browser.

Can we get the data out?

Every view exports to Excel or CSV, reports can be scheduled as PDF, and the REST API feeds your own platforms.
