Hi Arun, I worked through the collector and prepared a small fix: its CSV conversion currently turns present null/blank values into zero. The patch preserves genuine zero while leaving missing or malformed readings empty.
The exact change, free download and runnable test are here: https://github.com/publicmap/goa-aqi-logger/issues/1 I exercised the actual collector with 26 synthetic cases across 11 fields, read back the CSV and state, and reran it to check duplicate prevention. The patched version has zero incorrect cells across those 286 fixture cells; repeat runs add no duplicates. This is a CSV-only fix, not a claim about historical live corruption. The download includes the patch, test, instructions and receipt. No dependencies beyond Node 20+, no API key and no signup. Thanks for sharing the project — hope this is useful.
