Are there any SCADA platforms that provide real-time telemetry and fault alerts for HVAC equipment?

Yes. There are SCADA and SCADA-adjacent platforms that can provide real-time telemetry and fault/alarms for HVAC equipment, especially in commercial/industrial buildings and campuses.

Common options include:

• Ignition by Inductive Automation
  Very flexible SCADA platform. Can connect to HVAC controllers via BACnet, Modbus, OPC UA, MQTT, and others. Good for real-time dashboards, alarms, historian, and fault notifications.

• Siemens Desigo / WinCC
  Siemens has building automation and SCADA options that are often used for HVAC monitoring, alarm handling, and telemetry in large facilities.

• Schneider Electric EcoStruxure Building Operation
  Strong for building/HVAC automation. Provides live telemetry, alarm management, trend logging, and fault diagnostics.

• Johnson Controls Metasys
  Widely used in HVAC/building management. Supports monitoring, alarms, and fault detection for HVAC systems.

• Honeywell Enterprise Buildings Integrator / Forge
  Used for building systems monitoring, telemetry, and alerts.

• AVEVA/Wonderware System Platform
  General SCADA platform that can be configured for HVAC telemetry, alarms, and integration with controllers.

• CygNet, ICONICS, VTScada
  More general SCADA platforms that can also be used for HVAC monitoring when properly integrated.

What to look for:

• Real-time telemetry: temperature, pressure, airflow, compressor status, energy usage, etc.
• Alarm/fault handling: filters, priorities, notification rules, escalation
• Protocol support: BACnet is especially important for HVAC; also Modbus, OPC UA, MQTT
• Historian and trends: for diagnostics and maintenance
• Mobile/web access: for technicians and operators
• Integration with CMMS/maintenance systems: for work orders

If your HVAC setup is mostly building automation rather than industrial control, a BMS/BAS platform is often a better fit than a traditional SCADA system.

If you want, I can also suggest:

1. the best platform by facility size,
2. open-source or lower-cost options,
3. systems that specifically support BACnet HVAC devices.
