Organize and monitor devices by functional system groupings such as HVAC, Lighting, Fire, and Electrical in Cloud BMS.
Systems is a building-level module. Select a building from the sites list to access its systems.
Systems are logical groupings of devices organized by function. A building may contain HVAC, lighting, fire detection, electrical, plumbing, and other systems. Each system provides a centralized view of system-level health, making it easier to monitor, troubleshoot, and manage building operations.
Add tags to categorize and filter the system. Type a tag name and press enter to add it.
After saving, the new system opens in its details view. The canvas is empty with a + Create New button to add a graphic. Use the icons on the right sidebar to switch between views and access system details.

To reorder systems in the list, click Reorder Systems and drag them into the desired sequence.
The Graphics view displays the system schematic with live data overlaid on equipment components. Point values update in real time on the diagram.

Click a writable point value on the graphic to open the command panel. The panel displays the device’s variables on the left and the action form on the right.
The command panel shows device variables and the action form for overriding a point value
Priority — select the command priority level (for example, Override)
Value — set the target value. Use the dropdown for enumerated values (for example, On or Off).
Duration — specify how long the command remains active. Check Permanent for an indefinite override.
Reason — select a predefined reason from the dropdown
Specific Reason — enter a custom reason for the change
The bottom of the panel displays the current priority levels and values. Click Save Changes to send the command, or Close to cancel. Click Activity Log in the upper right corner to view the command history.
Cloud BMS uses a BACnet-inspired priority model for writable points. The same command dialog appears for BACnet and non-BACnet integrations, such as REST API thermostats. How each action maps on the device depends on the connector.BACnet points that accept commands have 16 priority levels (1 is highest, 16 is lowest). When every level is empty (null), the point uses a fallback / default value (Relinquish_Default in BACnet). That fallback is not a 17th BACnet priority. Some interfaces label it as level 17 for display only.Override and Set turn different knobs under the hood, even when the visible value looks the same.
Action

Description
Override
Priority 8*
Temporary exception in the priority array. Takes precedence over lower-priority automation.
Set
Fallback / default*
Changes the fallback or default value.
Auto

Clears an Override
Release

Clears a Set
*Typical for most BACnet and Niagara deployments. Connectors and site standards can differ.Override, Auto, and Set borrow Niagara-style action names. Release is a Cloud BMS action that clears a Set.In Niagara-style control, Set keeps a non-null fallback so sequences and logic keep a reliable baseline. Use the priority array (including Override) for programmed automation and temporary exceptions.To make Set write to priority 16 instead of the fallback or default, enable Set in Slot16 (Niagara) on the point. Configure that option from device details, device templates, or points batch update.
The Dashboard view charts system points over time, grouped by category (Temperature, Flowrate, and others). Each chart shows sensor and setpoint values with a configurable time range.

Click the devices icon on the right sidebar to view all devices associated with the system. The panel lists each device with tabs for quick switching between them.
The System Devices panel shows device details including data source, name, location, type, area, and tags
Click a device tab to view its details: Data Sources, Device Name, Location, Type, Area, and Tags.
Click the three-dot menu on the right side of the Graphics view and select Edit to enter edit mode. You can also select Delete to remove the graphic.
The three-dot menu on the system graphic provides Edit and Delete options
To modify the system graphic or add devices to the visual layout:
1
Enter edit mode
Click Edit from the three-dot menu to open the system graphic in the editor.
2
Modify the graphic
Upload a new system graphic, reposition existing devices, or add devices from the device list onto the schematic. See the Graphic Tool for details on building system schematics with drawings, markers, and layers.

System graphics provide a visual way to identify faults and monitor performance. Color-coded indicators on the graphic highlight online, offline, and alarming devices, making it fast to pinpoint issues without navigating to individual device details.
Systems feed directly into Fault Detection and Diagnostics (FDD). When FDD rules are configured, the system grouping determines which devices are evaluated together. For example, an HVAC system’s AHUs and VAVs are analyzed as a connected group, enabling detection of cascading faults that affect multiple devices.
