Smart Building Systems Integration for Energy Management and Automation
Ficode built the AWS-based integration layer using interfaces including BACnet controllers and MQTT devices. Alongside reading data and system states, supported connections allow the platform to issue authorised commands and check the value or state the equipment reports afterwards.
The project in context
In large commercial buildings, energy meters, HVAC equipment, lighting and management networks often use different interfaces. The client operated an energy intelligence platform that needed to bring these systems together for monitoring, analysis and configured actions. The integration work also covered third-party APIs, tenant systems, document storage and notification services.
Different building systems. Restricted commands. Results that need checking.
The client needed one platform to handle readings from equipment with different protocols, data formats and permissions. Reading telemetry was only part of the work. For systems that permit it, the platform also needed a controlled route for operator-initiated or rule-driven commands, followed by a check of the reported result.
The challenge Before
Different interfaces
Building systems expose different protocolsCommand restrictions
Not every system permits a write actionUncertain response
A command alone does not confirm the reported stateWith Ficode Connected Approach
Connect sources
Map supported systems into the platformAuthorised actions
Use permitted commands and configured rulesCheck read-back
Compare reported states after a commandConnect the interfaces. Apply the rules. Check the response.
Connect
Ficode established integration paths for BACnet controllers, MQTT devices and third-party APIs, alongside relevant tenant, document and notification services.
Evaluate
Processed readings can be checked against rules, schedules, thresholds and sensor values set by engineers.
Act
Supported integrations allow authorised setpoint changes, on/off actions, connected-system alarms and email notifications.
Verify
After a command, the platform reads the relevant reported value or state back and checks it against the requested action.

Map data and evaluate conditionsSupported commands
Operator or rule-triggered actionsCONNECTED OUTCOME
Read-back and configured follow-up. Check the equipment’s reported value or state; apply the configured action when an anomaly resolves or persists.
A platform that can monitor, respond and check
Connected building information
BACnet, MQTT and other supported interfaces bring readings and states from different systems into the energy platform.
Configured operating responses
Engineer-defined conditions and operator instructions can trigger supported actions such as setpoint changes, equipment switching, alarms and email notifications.
Read-back after commands
Following a supported command, the system reads the reported value or state back so the platform can check whether it matches the requested action.
Respect for system boundaries
Write access depends on each integration’s capabilities and permissions. Fire alarm and other life-safety interfaces remain subject to documented safety and operational restrictions.
Confirmed technology and implementation scope
AWS integration layer; BACnet, MQTT and third-party APIs; tenant systems, document storage and notifications.
