Steps
Run Companion on a machine on the room's local network and note its IP and port (the same port Companion's web UI is served on)
Lay out a button grid (page/row/column) representing your room-reset and control actions inside the Companion configuration UI
Trigger a button programmatically by sending a POST request to /api/location/<page>/<row>/<column>/press from your automation/game-master tooling
Use the equivalent /down and /up paths instead of /press when you need to simulate a held button rather than a single tap
Update a button's displayed style (text/colors) via POST to /api/location/<page>/<row>/<column>/style to reflect room state on a control-room display
For device-specific actions beyond generic button presses, route requests through the relevant Companion module's own HTTP handler at /instance/<module-label>/<endpoint>
Known gotchas
Companion's HTTP API controls the button grid abstraction, not devices directly — you still need a configured module/connection per piece of hardware for a button press to do anything downstream
There is no authentication on the HTTP remote-control API by default, so exposing Companion's port beyond the local room network is a real risk
Endpoint paths and available verbs have changed across Companion major versions (e.g. v4.x docs differ from earlier ones) — match your commands to the installed Companion version's documentation
