A Raspberry Pi command center stores incidents in SQLite, prioritizes them, recommends compatible resources and lets an operator authorize dispatch; the resource accepts and reports progress until the incident closes. An online replica (Vercel + Supabase) syncs pending events when internet returns but never executes critical actions.","demo_moment":"Not described publicly. The write-up lists LoRa messaging with acknowledgements between boards on real hardware, an offline dashboard, and an automatically verified flow from SOS through triage, dispatch, acceptance and resolution.","build_style":"hardware-software","tech":{"stack":["ttgo-lora32","esp32","lora","raspberry-pi","sqlite","python","captive-portal-wifi","vercel","supabase","3d-printing"],"ai_patterns":[]},"domains":["emergencies-disaster","robotics-hardware"],"analysis":{"why_it_stood_out":[{"claim":"Zero-install entry: a phone joins the node's Wi-Fi to report an emergency; delivery uses acknowledgements and retries over LoRa.","basis":"team-stated","source":0},{"claim":"Offline is the operational source of truth; the cloud hub only mirrors and syncs when the network returns, so a cloud failure never stops operations.","basis":"team-stated","source":0},{"claim":"Shipped beyond a slide: a public hub, an isolated demo command center, printable enclosures and a LoRa flow visualization.","basis":"team-stated","source":0},{"claim":"Entered the joint most crowded Bogotá track (7 of 24 submissions in Emergencies) with physical hardware and a one-line promise — works when the internet does not.","basis":"curator-inference","source":1}],"mechanisms":["physical-artifact","zero-install-channel","human-stakes","visible-engineering-depth","one-sentence-clarity"],"judging_lens":["technical-depth","impact","wow-factor"],"lessons":["State the failure condition the product survives (no internet) in the tagline; judges remember constraints.","Separate the operational path (local, authoritative) from the showcase path (cloud mirror) so the demo cannot be broken by venue Wi-Fi."],"confidence":"low"},"links":{"devpost":null,"repo":null,"demo":"https://woki-hub.vercel.app","video":null},"sources":[{"url":"https://hack.platan.us/26-co/vote/woki","kind":"voting-page","retrieved_at":"2026-09-14","note":"Team-written project page hosted by the organizer; no placement."},{"url":"data/hackathons/platanus-hack-26-bogota.json","kind":"voting-page","retrieved_at":"2026-09-14","note":"Track counts (full roster)."}],"curator_notes":"Placement unknown: official results pages returned server errors on 2026-09-14."}
