+# followspot-psn
+
+Solution for controlling followspots, and sending the position data to ma3 over
+[posistagenet (PSN)](https://posistage.net/). It uses
+[psn-py](https://github.com/vyv/psn-py) to do PSN stuff.
+
+### Deployment
+
+**TLDR**: `docker compose up --build` on a Linux machine.
+
+> [!NOTE]
+> Why Linux? This is because PSN uses multicast to transmit positional data to
+> ma3. On linux this is done using host networking driver. However the host
+> networking driver on macOS or windows will only allow broadcasting on the
+> docker linux VM. It could probably be done using some fancy routing/bridge
+> setup with the docker VM.
+
+This opens a webserver on port 8000 where you can control the PSN trackers. PSN
+data is multicasted on `236.10.10.10:56565`. Tracker positions can also be
+updated using OSC, by default OSC listens on port 9000. The OSC endpoint expects
+data on `/Tracker/{trackerid}` with three floats specifying x, y and z value.
+
+Currently all configuration is done in the source files, most notably in
+[psn_server.py](backend/psn_server.py).
+
+The rest of the functionality is documented in the code.
