The Niagara 4 Supervisor is an IoT (Internet of Things) software platform used in server-class applications. It makes managing all buildings at an enterprise level possible, giving facilities managers the ability to quickly respond to problems and insights to optimize their system. The Niagara 4 Supervisor allows multiple Niagara-based JACE® controllers, along with other IP-based controllers and field devices, to be networked together. It serves real-time graphical information to standard Web-browser clients and provides server-level functions. These functions include centralized data logging/trending, archiving to external databases, alarming, dashboarding, system navigation, master scheduling, database management, and integration with other enterprise software applications through an XML interface (oBIX standard). Also, it provides a comprehensive graphical engineering toolset for application development.


  • Centralized system management
  • Quickly navigate to individual buildings using tags to diagnose problems
  • Compare data between buildings
  • Export system data to external databases
  • Integrate BAS to other enterprise applications
  • Integrate to other applications, such as work order management, analytics, etc.
  • Single tool used to program JACE controllers and Supervisor
  • Remotely back up JACE applications to Supervisor
  • Batch provisioning of JACE firmware upgrades from Supervisor
  • Robust built-in analytic capabilities supported by standard Niagara components and visualizations
  • Compatibility with Niagara Analytics 2.0, adding data source, functional and mathematical programming blocks to enable sophisticated analytic algorithms

Supported drivers

Many open protocol drivers (optional) are included with Niagara 4:
Bacnet IP, LON IP, KNX IP, M-bus IP, Modbus TCP, oBiX, OpenADR, SNMP


Niagara Analytics version 2.0 is a data analytics extension to the Niagara Framework® available on Niagara 4 Supervisors and JACE® 8000 controllers. It gives Niagara 4 and JACE 8000 users the ability to apply a variety of analytic algorithms and diagnostics to both historical and real-time data available in Niagara. Users have the ability to discover and mitigate previously unknown operational issues, which helps to maximize their investment in Niagara Framework-based products. Niagara Analytics 2.0 is compatible with Niagara 4 version 4.2 and higher.
