FS25 FarmMonitor gives your Farming Simulator 25 game a second screen. A lightweight Lua mod continuously exports silo levels, production chains, animal husbandries, goods, and field states as JSON, while a small Go server picks them up and pushes live updates to a dark-themed web dashboard via Server-Sent Events — no browser refresh needed. Keep an eye on your entire farm from a second monitor, a tablet on the desk, or any device on your local network.
The dashboard updates automatically every few seconds — no refresh needed. All views are accessible via the sidebar.
A quick summary of your entire farm at a glance: KPI tiles show how many silos are active, how many production chains are running, how many animal stalls need attention, and how many alerts are currently open. Below the tiles sits a prioritised alert list that surfaces the most urgent issues across all categories — so you always know what needs attention first without having to browse through individual views.
A weather widget shows the current in-game conditions — weather type, temperature, wind speed and direction, rain intensity and ground wetness — alongside an hourly forecast for the next 6 hours and a 7-day daily outlook. The current in-game time and season period are displayed as well.
Work in progress: The Overview is currently the least developed part of the dashboard. What is shown here will continue to change — additional widgets, rearranged layout, new summary information. The final scope of this view has not been decided yet.
Cards for every vehicle on your farm showing current speed, fuel, AdBlue and battery levels, damage status, assigned driver and total operating hours. Clicking a card opens the detail panel with a full breakdown of all tanks, attached implements, purchase price, working width and vehicle colour. The fleet view supports filtering by shop category, free-text search by name, status filters and a "last moved" sort mode that puts recently active vehicles at the top.
AutoDrive status is shown directly on each fleet card — current mode, destination, remaining drive time and detailed state badges for every situation (loading, unloading, waiting for combine, driving to refuel or park, blocked, error, …). The vehicle detail panel includes a full AutoDrive control tab where you can set the operating mode, assign departure and destination markers, select the commodity to transport, and start or stop the route — all from the browser, without switching back to the game.
Courseplay job type, current waypoint progress and estimated remaining time are displayed on the fleet card and in the detail panel alongside AutoDrive whenever both mods are active.
An interactive map built on the farm's overview image. Field outlines are drawn as accurate polygons with field numbers placed at the centre of each field. All map hotspots — selling stations, production buildings, fuel stations, the shop, animal pastures and more — appear as colour-coded pins with tooltips. Live vehicle positions are updated every two seconds with smooth movement and direction arrows so you can follow your fleet in real time.
The map also supports several overlay layers that can be toggled via the legend. Field polygons can be coloured by current growth stage to see at a glance which fields are ready to harvest, still growing or already cut. Seven individual soil condition overlays — weeds, stones, ploughing, fertilising, liming, mulching and rolling — can be enabled to show the density map values across all fields as a colour-coded layer directly on the map.
The map supports mouse wheel zoom, click-and-drag panning and pinch-to-zoom on touch devices. Most elements on the map are clickable and open a detail panel on the right side:
- Vehicle pins — opens the full vehicle detail panel including tanks, implements and AutoDrive controls, identical to clicking a card in the Fleet view
- Field polygons — opens the field detail card showing crop, growth stage, soil conditions and the seed calculator
- Production building pins — opens the production card with input/output bars and output mode controls
- Animal husbandry pins — opens the stall card with food, water, straw levels and outputs
- Selling station pins — shows the station name; no price detail data is available directly on the map
Per-field cards covering everything you need to plan your next farm run. Each card shows the current crop, growth stage with a visual progress bar, a harvest-ready badge when the time has come, and an estimated yield bonus based on your soil conditions. Seven soil condition bars — ploughing, fertilising, liming, mulching, rolling, weed coverage and stone coverage — give you a complete picture of field health at a glance.
An interactive seed calculator lets you select any crop per field and instantly shows you the required seed quantity in litres per hectare and as a total for that field. The same calculator covers lime, fertiliser and herbicide so you can plan your refill runs before you even get on the tractor. Your crop selection is saved in the browser so you don't lose it when switching views.
Input and output bars for every production chain on your farm, colour-coded by fill level so you can spot bottlenecks instantly. Each card shows whether the chain is currently running, idle or stopped, and lists all ingredients and products with their current stock and capacity. Clicking any input ingredient takes you directly to that commodity in the Goods view.
Beyond monitoring, you can control your productions directly from the dashboard: change the output mode for any product (auto-store, direct sale, or pallet output) without opening the game, and trigger the immediate ejection of a full pallet for any output — right from the browser. This works for any production building that supports pallet output, including mod productions. Individual production buildings can be hidden via the Edit view button; visibility is saved per savegame.
Per-stall cards showing current and maximum occupancy, all food groups with fill levels (with smart weighting for parallel feeders like pigs, where not every group is equally important), water and straw levels, average animal health and all outputs like milk, manure or eggs. Alert status is colour-coded — OK, Watch, Warning or Critical — and thresholds are fully configurable per resource type in the Settings view. Individual stalls can be hidden via the Edit view button; visibility is saved per savegame.
An aggregated overview of everything you own, sorted by commodity. Each row shows your total stock across all storage types on the farm, the current best selling price available at any station on the map, the seasonal maximum price and the best month to sell, the current trend (rising, falling or high demand), and a colour-coded rating of how the current price compares to the seasonal peak.
From the Goods view you can also act directly: for any commodity that is produced by one or more of your production buildings, you can change the output mode or trigger a pallet ejection across all relevant productions at once — without having to visit each production card individually.
Fill-level bars for every storage location on your farm — silos, silo extensions, bunker silos (with fermentation progress and compaction level), bale and pallet storage buildings, and manure heaps. Filter buttons at the top let you narrow the view to a specific storage type. Each entry shows its current fill levels by commodity so you always know what you have and how much space is left. Individual storage entries can be hidden via the Edit view button; visibility is saved per savegame so hiding a building on one map does not affect other saves.
The Alerts view consolidates every active warning and critical state across all categories — animals, productions, silos and fields — in one place, sorted by severity.
The Settings view is split into several sub-sections:
Server — adjust the HTTP port and listen address (changes take effect after a server restart), and override the data directory or mod folder path if auto-detection does not find the right location.
Detected mods — shows which optional mods are recognised by FarmMonitor (AutoDrive, Courseplay, ProductionStorageControl, EnhancedVehicle, VehicleInspector). Detection status updates when a savegame is loaded.
Mod configuration — configure export intervals for each data type (main export covering silos/productions/husbandries/goods, vehicles, fields, weather, IPC command polling), and tune the soil map overlay quality (grid resolution and rows sampled per game tick). A diagnostics section lets you enable performance logging to log.txt and export a full performance report.
Alert thresholds — Silos — set the warn and critical fill percentages for the silo quicknav dot indicators.
Alert thresholds — Husbandries — set separate warn/critical thresholds for inputs (food, water, straw), outputs (milk, eggs, manure, …), and stall occupancy (watch and warn levels).
Alert thresholds — Fields — set yellow and red thresholds for each soil condition: ploughing, fertilising, liming, mulching (all trigger below a percentage) and weeds and stones (trigger above a percentage).
Visibility — toggle individual silos, production buildings, animal stalls and fields on or off per savegame. Hidden entries are removed from all views and alerts. Visibility is stored per savegame so changes on one map do not affect other saves.
Multiplayer: every player runs the mod locally and sees their own farm's data. Singleplayer and player-hosted multiplayer are fully supported.
FarmMonitor has two independent parts that communicate through plain JSON files on disk — no network connection between them is required.
Inside the game (Lua mod)
A lightweight Lua mod runs inside Farming Simulator 25 and hooks into the game's update() loop. Every 10 seconds it reads live data from the game's internal APIs — silo fill levels, production chains, animal stalls, vehicle states, field conditions — and writes everything out as JSON files to the FS25 modSettings directory. Some data that rarely changes (fill type definitions, fruit type growth stages, animal food recipes) is written only once when the map is loaded. Field soil conditions are sampled every 60 seconds via low-level density map queries.
The mod never reads from or writes to the internet, never opens any ports, and never modifies any game state on its own.
Outside the game (Go server)
A small Go binary (farmmonitor) watches the JSON files for changes using a file watcher. Whenever a file is updated the server parses it and immediately pushes the new data to all connected browser clients via Server-Sent Events (SSE). The dashboard HTML and all assets are embedded directly in the binary — there is no separate install step and no internet dependency. The server automatically detects the modSettings data directory — no configuration needed unless you want to override it.
In the browser (dashboard) The dashboard is a single-page app that opens a persistent SSE connection to the server and re-renders any section that received new data. Because SSE is a one-way push channel, the browser never has to poll — updates appear automatically as soon as the mod writes them.
FS25 (game process)
└── FarmMonitor.lua ← reads game APIs every 10 s
└── writes JSON files ← modSettings folder on disk
farmmonitor (Go binary)
└── watches JSON files ← file watcher, no polling delay
└── pushes SSE events ← to all open browser tabs
Browser (dashboard)
└── SSE connection ← persistent, automatic updates
IPC commands (AutoDrive control, production output mode changes, pallet ejection, player teleport) travel the same path in reverse: the dashboard sends an HTTP request to the Go server, which writes an XML command file to the modSettings folder, and the Lua mod reads and executes it on the next update tick.
The server persists two kinds of settings as plain JSON files in the platform config directory — no database required:
| Kind | API | File location |
|---|---|---|
| Global dashboard settings | GET/PUT /api/settings |
<configDir>/FS25_FarmMonitor/settings.json |
| Per-savegame placeable visibility | GET/PUT /api/savegame/{savegameId} |
<configDir>/FS25_FarmMonitor/savegames/<hash>.json |
Platform config directories:
- macOS:
~/Library/Application Support/ - Windows:
%APPDATA%\ - Linux:
~/.config/
Global settings include alert thresholds for all resource types. Placeable visibility is stored per savegame (identified by savegameId) so hiding a building on one map does not affect other saves.
All files are written to:
- macOS:
~/Library/Application Support/FarmingSimulator2025/modSettings/FS25_FarmMonitor/ - Windows:
Documents/My Games/FarmingSimulator2025/modSettings/FS25_FarmMonitor/
All JSON files include a savegameId field composed of mapId + "_" + creationDate (e.g. MapUS_2026-02-15). This uniquely identifies the active savegame and is used by the server to scope per-save settings.
All farm vehicles: position, heading, speed, fuel/AdBlue/battery/methane levels, damage, operating hours, assigned driver, engine state, attached implements, AutoDrive status (mode, destination, remaining time, state flags), Courseplay status (job type, waypoint progress, remaining time).

FarmMonitor integrates with FS25_AutoDrive by Stephan Schlosser (MIT License) to display AutoDrive status information and allow basic control from the dashboard.
FarmMonitor does not bundle or distribute any AutoDrive files.
If AutoDrive is installed, the FarmMonitor server reads FS25_AutoDrive.zip directly from the user's own FS25 mods folder at startup. Icons are extracted from that ZIP, recoloured in memory to match the dashboard's colour scheme, and cached for the current session only. Nothing is written to disk and nothing is redistributed. If AutoDrive is not installed, the integration is silently skipped.
The Lua side interacts with AutoDrive through two mechanisms:
vehicle.adStateModule API — reading vehicle state (stateModule:isActive(),stateModule:getMode(), marker names, remaining time, etc.) and sending control commands (sm:setMode(),sm:setFirstMarker(),currentMode:start(),vehicle:stopAutoDrive(), …). These are the methods documented in AutoDrive'sscripts/ExternalInterface.luaandscripts/Specialization.lua.AutoDriveUpdateSettingsEvent— changing AutoDrive settings (pipe offset, follow distance, corner speed, restrict-to-field, etc.) by firing the same internal network event that AutoDrive's own in-game UI uses. This is the only correct way to change settings and have them synced to all clients; direct field writes alone are not sufficient in multiplayer.vehicle.ad.settings[name]is also read directly to query the current value.
The full technical breakdown of both command paths (singleplayer, listen-server, dedicated server) is documented in ai/api_autodrive_commands.md.
