The Ark Core

② The Manifest

The parts list. Cores are what you actually need; “if you prefer” opens cheaper, local, or heritage swaps — never budget fallbacks, just other good ways.

③ The Sequence

1. 01Set up Pi20 min Install Raspberry Pi OS Lite. Connect to network or run standalone.
2. 02Install meshtasticd10 min pip install meshtastic. Configure USB serial to Heltec.
3. 03Verify mesh5 min Run meshtastic --listen. Confirm Sentry packets arriving.
4. 04Install logic layer30 min Install Home Assistant or write Python listener. Start with one alert rule.
5. 05Test command path10 min Send GPIO write to a remote Actuator. Confirm relay responds.
6. 06Build rulesongoing Add one rule at a time. Test each. Start passive (alerts), graduate to active (actuation).

How this rig connects to the rest of the Ark.

• ← community The License Rig Local HAM net check-ins, ARES emergency traffic, and weather reports feed situational awareness into the Ark Core
• ← information The Base Station Winlink email, HF net traffic, and propagation data feed long-range situational awareness into the Ark Core when internet-based sources are unavailable
• ← information The Gray Link Broadband internet feeds firmware updates, remote monitoring dashboards, weather data, and supply ordering into the Ark Core — the convenience layer that makes the brain smarter
• ← information The Whisper Node The Whisper Node is the user-facing entry point onto the mesh; the Ark Core is the automation brain that receives all mesh traffic. Human-typed messages, position pings, and forwarded sentry telemetry flow from the Whisper Node into Ark Core for processing, alerting, and rule-based response. The household interacts with the mesh through the Whisper Node app interface; Ark Core watches and acts on the data.
• ← information The Sentry The canonical destination for all Sentry telemetry and detection data. The Ark Core receives every Sentry packet on the mesh, applies rules, fires alerts, triggers Actuators when configured, and logs historical data for The Ledger. Without the Ark Core, individual Sentries broadcast into the void; with it, the Sentries become a coherent property nervous system.
• ← information The Relay Tower The Relay Tower's primary outbound function — forward distant Sentry telemetry, Whisper Node messages, and Actuator command-acks to the Ark Core. Without the relay, sensors at the property edge are out of reach of the Core; with it, the Core sees the entire property as one logical mesh. The relay is invisible to most of the data it carries — packets pass through transparently — but every long-distance flow on the property goes through it.
• → information The Watch Time sync, node registry, and shared channel config come IN from The Ark Core so every sensor node speaks the same mesh and logs to a common record.
