Live data with FRM

Live data with FRM (optional)

Without a mod, the map shows the state of the last autosave (usually 5 minutes old). With the mod FicsIt Remote Monitoring (FRM) it becomes live:

	save only	with FRM
Players, trains, trucks	every ~5 min, jumping	every 5 s, moving smoothly
"online" / follow mode	unknown	yes
Machines, power, item balance	every ~5 min	every minute
Stations, schedules, belts, foundations	from the save	from the save
Train throughput, round-trip times	–	yes

The top right always shows honestly where the data comes from: live (green) or save N min ago (yellow).

⚠ Know this first

• All players need the same mods (Satisfactory Mod Loader + FRM, same version). Without them, you can no longer join the server — the server log does not even show a connection attempt. FRM's description says "server-only", but in practice that is not true.
• Mods can break after game updates until they are updated. In that case, simply clear FRM_URL — the map keeps running from the save.

Setup

1. Clients: every player installs the Satisfactory Mod Manager and, in it, FicsIt Remote Monitoring (which brings the mod loader along).
2. Server: download SML + FRM in the server variant (LinuxServer / WindowsServer) from https://ficsit.app and install them:
   • .smod files are ZIP archives. Unpack SML to FactoryGame/Mods/SML/, FRM to FactoryGame/Mods/GameFeatures/FicsitRemoteMonitoring/ (not directly under Mods/ — otherwise the mod loads but does nothing).
   • Start the server once and stop it again.
   • In FactoryGame/Saved/Config/LinuxServer/GameUserSettings.ini (Windows: WindowsServer), replace the line mIntValues=() with mIntValues=(("FicsitRemoteMonitoring.Server.uWS.Autostart", 1),("FicsitRemoteMonitoring.Server.uWS.Port", 8080)) — only edit while the server is stopped, otherwise the game overwrites the file.
   • Start the server. LogHttpServer: Port 8080 unavailable in the log is normal.
   • Pterodactyl: the script tools/install_frm_pterodactyl.sh does all of this via SSH on the Wings host.
3. Map: set FRM_URL=http://<server>:8080 in .env and run docker compose up -d.
4. Check: curl http://<server>:8080/getSessionInfo returns JSON. Without Docker: FRM_URL=… python3 frm.py probe.

Keep port 8080 internal

The FRM port does not belong on the internet — the map queries it, visitors do not need it. If it is only available in a container network (Pterodactyl), an SSH tunnel on the map's machine helps:

ssh -N -L 18080:<container-ip>:8080 root@wings-host

and FRM_URL=http://127.0.0.1:18080 (with Docker: http://host.docker.internal:18080 with extra_hosts: ["host.docker.internal:host-gateway"] in docker-compose.yml).

Known issue: "World not ready" after a session restart

The dedicated server reloads the session regularly (Session Restart Time, at night by default). Afterwards, FRM sometimes keeps answering Blocked API call: World not ready. The map then shows "save N min ago" and keeps running from the save. Workaround: fully restart the server process once, shortly after the session restart (e.g. a Pterodactyl schedule "Power Action: restart", only when online).
