+# Farm Aggregator
+
+A lightweight Node.js service that runs on the farm server. It pulls data from AG-Refine and Dropbox, synthesises it with Claude Haiku, and pushes summaries back to Dropbox and WhatsApp on a schedule.
+
+## Data flow
+
+```
+AG-Refine (Render) ─┐
+DairyComp logs     ──┤  Dropbox  ──→  farm-aggregator  ──→  Haiku  ──→  Dropbox /Summaries
+FeedLync files     ──┘                      │                              WhatsApp
+                                            │
+TomTom geofence webhooks  ────────────────→─┘
+```
+
+## Setup
+
+### 1. Install Node.js 20+
+Download from https://nodejs.org/
+
+### 2. Clone the repo and install dependencies
+```bat
+cd farm-aggregator
+npm install
+```
+
+### 3. Create your .env file
+```bat
+copy .env.example .env
+notepad .env
+```
+
+Fill in:
+- `ANTHROPIC_API_KEY` — your Anthropic key
+- `DROPBOX_*` — see Dropbox section below
+- `WHATSAPP_*` — optional, leave blank to skip
+
+### 4. Dropbox OAuth setup
+
+1. Go to https://www.dropbox.com/developers/apps and create an app
+2. Set permissions: `files.content.read`, `files.content.write`
+3. Generate an access token OR set up the refresh token flow
+4. Copy App Key, App Secret, and Refresh Token into `.env`
+
+### 5. Start the service
+```bat
+start.bat
+```
+
+Or to run as a Windows service (stays running after logout):
+```bat
+npm install -g node-windows
+node install-service.js
+```
+
+## Schedules
+
+| Job | Default | What it does |
+|-----|---------|--------------|
+| Pulse | Hourly | Quick snapshot — tickets, lab flags, ops |
+| Daily | 06:00 | Full daily digest pushed to Dropbox + WhatsApp |
+| Weekly | Mon 06:00 | Weekly summary (Sonnet, deeper analysis) |
+
+Change schedules in `.env` using cron syntax.
+
+## TomTom geofencing
+
+1. In TomTom Geofencing API, create fences for each field boundary
+2. Set webhook URL to `http://YOUR_SERVER_IP:3001/webhook/tomtom`
+3. Entry/exit events are logged to Dropbox and sent to WhatsApp
+
+## Manual triggers (testing)
+
+```bash
+curl -X POST http://localhost:3001/run/pulse
+curl -X POST http://localhost:3001/run/daily
+curl -X POST http://localhost:3001/run/weekly
+```
+
+## Planned integrations
+
+- **iyohtah / nTELL AI** — herd health data once API access is confirmed
+- **Daitrix** — AI camera feed events (scale automation, pen detection)
+- **Oracle Cloud** — heavy data processing offload
