I know @Wotever wrote an amazing replacement for the Elgato Stream Deck software to turn it into a proper button box, but if you want to use your Stream Deck for multiple purposes I've made a plugin that will allow you to trigger any Simhub event using the SD with stock software. Just install the plugin, give your new button a name and press that button while in the "Controls and Events" section when creating or editing a trigger. That's it, nothing fancy but means you can now have a dedicated Sim profile while also using all of the other Stream Deck functionality.
