The future is open for business

Honeywell Optimizer Supervisor builds on the Niagara Framework™, using the freedom of a truly open platform to give your building tomorrow’s capabilities, today.

The open alternative: Honeywell Optimizer Supervisor

A truly open framework, Honeywell Optimizer Supervisor helps businesses take full advantage of the Internet of Things. The latest release, Niagara N4.13, includes a host of new features to support you as you distribute more control and management tasks to intelligent edge devices.
Improved security

Better authentication requires both strong credentials and encrypted data. “Role-based access control” (RBAC) makes user permissions easy to configure and less error-prone. All user actions and security-related events are recorded in the security log for traceability.

Easy conversion

The native Niagara Fox protocol will work between the Niagara AX and Niagara 4 software systems, and the Niagara 4 software will work with any currently available Honeywell Optimizer Suite controller. A station-conversion tool adapts Niagara AX stations to Niagara 4 stations.

Data that works for you

Easily conduct system-wide searches. Create customized charts with a simple drag and drop. No need to engineer new dashboards each time requirements change.

Faster, more powerful development

Developers will find improved documentation, a rich open API library, BajaScript 2.0, semantic data modeling via tags, and other readymade tools that speed and support development. New features and public APIs make it easier to extend, develop and build upon the framework.
