Companion — Presentation Commander Server
The Presentation Commander server on a Stream Deck

What it does
A Bitfocus Companion module for the Presentation Commander server, for driving a running master server from a Stream Deck or any other Companion surface.
It talks to the server's existing JSON-RPC automation API on port 9700 over plain HTTP, so there's nothing extra to install on the server.
- Actions: route output, blackout output, recall scene to output, send a note to stage, next and previous slide
- Every output, scene, source and client dropdown is populated live from the server's current state, so the lists always match what is actually configured
- No hand-typed ids anywhere
- The API has no authentication and binds loopback by default — reach it across machines through an SSH tunnel or an authenticating reverse proxy
Where it stands
Released. It isn't in the official Companion module store, so install it as a developer module.
