I need an end-to-end software layer that pulls live weight readings from our industrial scales, stores the data, and instantly publishes clean, branded PDF reports. The scales stream their output via RS-232/Modbus, so your solution must listen to that feed, validate each read, and write it to a small SQL or time-series store where we can query and display trends. The moment a new reading lands, an operator should be able to open a browser page and watch totals tick up in real time; at the same time, a “Generate Report” button must compile the latest data into a PDF that we can hand straight to QA or shipping without extra formatting. Key deliverables • A lightweight service (Python, Node, or similar) that consumes the scale signal and logs it reliably • Simple web dashboard showing live values and historical graphs • One-click, well-formatted PDF report with logo, timestamp, and batch metrics • Installer or clear setup script plus concise documentation Acceptance criteria 1. Live read appears on the dashboard within two seconds. 2. Generated PDF matches provided sample layout and opens on any standard viewer. 3. No lost data after 24-hour soak test. If you have experience with industrial equipment interfaces and PDF report generation libraries like JasperReports, ReportLab, or equivalent, I’d like to see it. Let’s keep the code modular so future exports to CSV or Excel remain an easy add-on.
