# 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.
