System Requirements

Niagara 4 System Requirements

• Reflow requires Niagara 4.6 or later running on a Web Supervisor or JACE 8000 (or equivilent) hardware

• Reflow’s module size is approximately 8.5 MB. It is recommended to have 50 MB of free space on your station’s file system before installation, and keeping at least 40 MB of file space dedicated to Reflow during usage, this space is used to store configuration data.

• Reflow does not require additional memory or CPU upgrades and its impact on station memory, heap size, and CPU usage should be negligible. Please note that if your station is already at maximum memory or CPU capacity, adding any module, including Reflow, may be detrimental to your system.

Web Browser Support

• Reflow supports all modern “evergreen” web browsers including the latest versions of Chrome, Edge, Firefox and Safari.

• Specific browser version support includes the release up to two versions back from the time the Reflow version was released

• Reflow does not support Internet Explorer

• Reflow supports all iOS web browsers on iOS 14 or later

• Reflow supports Android web browsers which are compliant with Chrome 64 or later. It is recommended to use the latest release of Chrome on Android when possible

• Reflow does not support Internet Explorer

Security Considerations

• Reflow inherits the Niagara security model. You can control access to Reflow in the same way you can control access to any component in your station.

• Users/categories who do not have access to specific station components, points, devices, graphics, etc. will still not have access to these items in Reflow.

• Reflow uses Niagara’s built-in Web Service to serve all files and web requests. If HTTPS is enabled on the Web Service, requests will be served over HTTPS. If the WebService is disabled, Reflow will also be disabled.

Weather Data

• Reflow uses AerisWeather for weather data including current conditions, forecasts, and live precipitation maps.

• The Reflow module on the station will never directly connect to the weather data provider. This connection is made in the end user’s web browser and will have no impact on station performance.

• An internet connection from your station is not required to use these features, however end users who wish to see this data must have an active internet connection and be authorized to connect via HTTPS to weather.niagaramodules.com from their local network.

• The Reflow weather data provider caches weather station data for current conditions and forecasts for up to 15 minutes. Weather map images are cached for up to 30 minutes.

Map Data

• Reflow uses data and map tile images from MapBox to display interactive maps in on dashboards, building pages, and in the configuration.

• The Reflow module on the station will never directly connect to map data providers. This connection is made in the end user’s web browser and will have no impact on station performance.

• An internet connection from your station is not required to use these features, however end users who wish to see this data must have an active internet connection and be authorized to connect via HTTPS to mapbox.com and geocode.niagaramodules.com from their local network.

License System

• Site product licenses never expire and validate for all Host IDs. They are valid for all future versions of Reflow 1.x.

• Integrator Demo product licenses expire one year from their purchase date and validate for any Host ID with an expiration date not equal to “never” in its Niagara license file. Active licenses are valid for all versions future of Reflow 1.x.

• When an internet connection is available, the ReflowService will connect to the host api.niagaramodules.com over HTTPS to refresh its license file once every 24 hours. This will automatically push out the license file expiration date.

• If an internet connection is not available, license files can be installed manually.

• When the manual installation method is used or if an internet connection is no longer available, licenses with expiration dates will have to be updated manually when they expire.

• Legacy JACE and JACE Pro product licenses never expire and validate only supported Host IDs*. They are valid for all future versions of Reflow 1.x.

• Legacy Supervisor product licenses never expire and validate only for non-JACE/JACE Pro Host IDs* including WIN and LNX. They are valid for all future versions of Reflow 1.x.

• Valid JACE and JACE Pro Host IDs include those starting with QNX, LYX, WEBX, GC5, and PXC.
