+# POS-Automation Context
+
+## Overview
+POS-only daily news briefing for the **Epson TM-m30** receipt printer.
+Fetches unread articles from FreshRSS, selects and summarizes them via Ollama, then sends a native ESC/POS receipt over TCP to the printer. No PDF generation, no CUPS, no full-size printer support.
+
+Forked from `Seth/PrinterAutomation` on Gitea.
+
+## Components
+- `pos_briefing.py` — Main script. Run directly or via cron.
+- `config.json` — Credentials and endpoints (not committed).
+- `config.example.json` — Template for config.json.
+
+## How It Works
+1. Logs into FreshRSS (Google Reader API), fetches up to 100 unread items.
+2. Sends headlines to Ollama — Phase 1 selects top 5, Phase 2 summarizes each in 30-50 words.
+3. Collects dashboard data: weather (open-meteo), ZFS status (SSH to remote host), Grafana metrics, market data (yfinance), Uptime Kuma alerts (pct exec).
+4. Builds ESC/POS receipt bytes via `python-escpos` (Dummy printer).
+5. Sends raw bytes to printer via TCP socket on port 9100.
+6. Marks articles as read in FreshRSS.
+
+## Configuration (`config.json`)
+| Key | Description | Example |
+|---|---|---|
+| `freshrss_url` | FreshRSS base URL | `http://192.168.0.157` |
+| `freshrss_user` | FreshRSS username | `Admin` |
+| `freshrss_api_key` | FreshRSS API password | `seth123!` |
+| `ollama_url` | Ollama instance URL | `http://192.168.0.141:11434` |
+| `ollama_model` | Model name | `qwen2.5:1.5b` |
+| `yourls_url` | YOURLS API endpoint | `http://192.168.0.152:8080/yourls-api.php` |
+| `yourls_user` | YOURLS username | `admin` |
+| `yourls_pass` | YOURLS password | |
+| `grafana_url` | Grafana base URL | `https://monitor.atermiter-x79.xyz` |
+| `grafana_token` | Grafana service account token | `glsa_...` |
+| `remote_host` | Host to SSH into for ZFS status | `192.168.0.197` |
+| `remote_pass` | SSH password for remote_host | |
+| `printer_ip` | TM-m30 IP address | `192.168.0.137` |
+| `printer_port` | ESC/POS TCP port (default 9100) | `9100` |
+
+## Infrastructure
+- **Printer:** Epson TM-m30 at `192.168.0.137`, ESC/POS TCP port 9100.
+- **FreshRSS:** CT 120, `192.168.0.157` / `fresh.sethpc.xyz`.
+- **Ollama:** `192.168.0.141` (Gaming PC, `steel141`). Model: `qwen2.5:1.5b`.
+- **YOURLS:** `192.168.0.152:8080` — shortens article URLs printed on receipt.
+- **Grafana:** `monitor.atermiter-x79.xyz` — Proxmox node metrics (173, 112, 197).
+- **ZFS:** SSH to `192.168.0.197` (node-197) — queries `zpool list tank`.
+- **Uptime Kuma:** CT 147 — queried via `pct exec 147` (requires Proxmox host).
+- **This script runs on:** CT 166 (`192.168.0.175`, OpenClaw2).
+
+## Cron
+Runs daily at 04:30 via crontab on CT 166:
+```
+30 4 * * * python3 /root/bin/POS-Automation/pos_briefing.py >> /var/log/pos_briefing.log 2>&1
+```
+
+## Setup
+```bash
+pip3 install requests python-escpos yfinance qrcode
+apt install sshpass
+cp config.example.json config.json
+# Edit config.json with credentials
+python3 pos_briefing.py
+```
+
+## Known Issues / Notes
+- `pct exec 147` (Uptime Kuma check) only works on a Proxmox host, not inside a CT — silently returns None.
+- `printer_ip` direct access (`192.168.0.137`) may be unreachable from some CTs due to Proxmox bridge/firewall state; pinging first resolves intermittent ARP issues.
+- FreshRSS direct IP (`192.168.0.157`) can be intermittently unreachable from CT 166 — `fresh.sethpc.xyz` (via Caddy) works as fallback but adds latency.
+- yfinance ETH-USD occasionally fails with a NoneType error — non-fatal, other tickers still print.
