SimHub Plugin

Overview

The MAIRA SimHub plugin gives SimHub access to some real-time MAIRA properties, so you can add stuff to your custom dashboards. This feature was added in v0.55 of MAIRA.

Installing

Installing the plugin is pretty straightforward. After you install MAIRA, there will be a file called MarvinsAIRASimHub.dll located at %USERPROFILE%\Documents\MarvinsAIRA, where %USERPROFILE% usually is C:\Users\{User}, with {User} being the name you use to log into Windows. Just drag and drop this file into your SimHub program files folder, which is usually at C:\Program Files (x86)\SimHub.

After copying the plugin into the SimHub folder, when you run SimHub it will ask you if you want to enable the plugin.

Click on the toggle switch to allow SimHub to enable the plugin and click on the Ok button.

Parameters

After you enable the plugin, a bunch of properties will become available to you to include in your SimHub dashboards. To find these properties you can click on available properties on the left side menu and type “Marvin” into the filter box.
