# MeshAI

**An LLM-powered assistant for LoRa mesh networks — on Meshtastic *and* MeshCore, at the same time.**

MeshAI connects to your mesh, watches network health and the world around it in real time, answers questions over the air, and broadcasts the alerts that matter — weather, wildfire, road, seismic, RF, and mesh-health — with a full web dashboard to drive it all.

> ### 🤖 Built with AI ("vibecoded")
> In the interest of transparency: **MeshAI was vibecoded** — designed, built, debugged, and documented in close collaboration with LLM coding assistants. The architecture, most of the implementation, and this README were produced that way. It's a real, running project on a live mesh, but expect the pragmatic style, opinionated shortcuts, and occasional rough edges that come with the territory. Issues and PRs are welcome.

## Highlights

- **Dual-transport** — runs on **Meshtastic** and **MeshCore** simultaneously. Each mesh is first-class: independent connection, routing, and behavior, one shared brain.
- **Conversational bot** — DM it "how's the mesh?" or ask about weather, fires, roads, or a specific node, and get a data-driven answer over LoRa. The reply goes back on whichever mesh you asked from.
- **Per-mesh awareness** — it watches chat on each mesh separately (rolling short-term memory), so "what's happening on the mesh?" answers about *your* mesh. Private DMs stay private; curated knowledge stays separate.
- **Broadcast intelligence** — weather alerts, wildfire updates, road/traffic, seismic, RF/band conditions, and mesh-health notifications, formatted to fit LoRa and routed per-mesh, per-family.
- **Mesh health** — a 5-pillar health score with per-region breakdowns, infrastructure monitoring, coverage-gap analysis, and battery/solar tracking (Meshtastic).
- **Web dashboard** — a clean React UI to configure every transport, route every message type, watch a live activity feed, browse contacts, and tune the bot — no config-file spelunking required.
- **Knowledge base (RAG)** — optional hybrid retrieval over a large curated vector store for survival/comms/technical Q&A.
- **Multi-backend LLM** — Google Gemini, OpenAI, Anthropic, or any OpenAI-compatible local model (Ollama, LiteLLM, etc.).

## The dashboard

Everything is driven from the web UI, organized into **General**, **Meshtastic**, and **MeshCore** sections — each mesh mirrors the other so there's nothing to relearn when you add the second transport.

**Live activity log** — every broadcast, on both meshes, with per-mesh badges and Sent/Skip status:

![Activity Log](https://raw.githubusercontent.com/zvx-echo6/meshai/main/docs/images/activity.png)

**Per-family routing** — decide exactly where each message type goes: broadcast vs. DM, which channel, which recipients — independently for each mesh:

![Routing](https://raw.githubusercontent.com/zvx-echo6/meshai/main/docs/images/mt-routing.png)

**MeshCore contacts & companion** — the live roster from your MeshCore companion node, with names, types, last-heard, position, and optional telemetry polling:

**Data feeds** — turn environmental sources on/off and tune thresholds in one place:

**Nodes & health** — per-node infrastructure detail: battery, utilization, coverage, neighbors, hardware:

## Quick start

```bash
git clone https://github.com/zvx-echo6/meshai.git
cd meshai
pip install -e .
meshai --config     # interactive setup TUI
meshai
```

Or with Docker:

```bash
mkdir -p meshai/data && cd meshai
curl -O https://raw.githubusercontent.com/zvx-echo6/meshai/main/docker-compose.yml
curl -o data/config.yaml https://raw.githubusercontent.com/zvx-echo6/meshai/main/config.example.yaml
# edit data/config.yaml, then:
docker compose up -d
```

The dashboard comes up on `http://localhost:8080`.

## Transports

MeshAI speaks two mesh protocols. **Meshtastic is always the base transport.** **MeshCore turns on automatically the moment you set a MeshCore host** — there's no separate on/off toggle to forget.

### Meshtastic

Connect over TCP (recommended) or serial:

```yaml
connection:
  type: "tcp"           # or "serial"
  tcp_host: "192.168.1.100"
  tcp_port: 4403
  # serial_port: "/dev/ttyUSB0"
```

### MeshCore

MeshAI attaches to a MeshCore **companion** (the pyMC / MeshCore companion frame server) over TCP and acts as a node on the MeshCore mesh:

```yaml
connection:
  meshcore_host: "192.168.1.253"   # blank = MeshCore off
  meshcore_port: 5050
```

Once connected, MeshCore gets its own **Connection**, **Routing**, **Scheduled Broadcasts**, **Contacts & Companion**, and **Danger Zones** pages in the dashboard — the same capabilities as Meshtastic, using MeshCore's own idioms (channels by name, contacts by pubkey). Messages are sized to fit whichever mesh they go out on.

---

## The conversational bot

DM MeshAI on either mesh and it answers with the LLM, using live mesh data, environmental feeds, and (optionally) a knowledge base. A few things it's careful about:

- **Answers on the mesh you asked from.** A MeshCore DM gets a MeshCore reply; a Meshtastic DM gets a Meshtastic reply. Each mesh's "answer DMs" switch is independent.
- **Per-mesh chat memory.** It keeps a short rolling window of recent channel chatter *per mesh* (configurable retention, default 14 days) so "what's happening on the mesh?" reflects the mesh you're on. Ask about the other mesh by name to cross over.
- **Three separate lanes.** Shared channel context, your private DM history, and the curated knowledge base never bleed into each other.
- **LoRa-fit replies.** Responses are chunked to a per-mesh character budget with sentence-aware splitting and continuation prompts.

### Commands

Alongside natural-language questions, a set of `!` commands are available (all toggleable, so they can defer to another service like MeshMonitor):

| Category | Commands |
|----------|----------|
| Mesh | `!health` · `!mesh` · `!status` · `!region [name]` · `!neighbors [node]` |
| Weather / RF | `!wx-alerts` · `!solar` · `!hf` · `!satpass` |
| Fire | `!fire` · `!hotspots` · `!ignitions` |
| Hazards | `!avalanche` · `!roads` / `!traffic` · `!rivers` / `!gauges` |
| Utility | `!help` · `!clear` |

---

## Mesh intelligence (Meshtastic)

MeshAI continuously aggregates mesh data and computes a **5-pillar health score**:

| Pillar | Weight | Measures |
|--------|--------|----------|
| Infrastructure | 30% | Router/repeater uptime |
| Utilization | 25% | Channel busyness / RF congestion |
| Coverage | 20% | How many monitoring sources see each node |
| Behavior | 15% | Traffic patterns (noisy/misconfigured nodes) |
| Power | 10% | Battery health of infrastructure nodes |

Infrastructure nodes are tracked individually (battery, offline alerts, coverage, neighbors, hardware); client nodes coming and going is normal and ignored. Regions are fully configurable — local names, aliases, cities, and radius — with no hardcoded geography.

Data comes from one or more **Meshview** instances and a **MeshMonitor** instance, polled on a staggered schedule with built-in rate-limiting:

```yaml
mesh_sources:
  - name: "meshview"
    type: meshview
    url: "http://192.168.1.100:8080"
    enabled: true
  - name: "meshmonitor"
    type: meshmonitor
    url: "http://192.168.1.100:3333"
    api_token: "your-bearer-token"
    enabled: true
```

---

## Environmental & hazard feeds

MeshAI pulls real-time situational data and turns it into LoRa broadcasts and query answers. Sources include **NWS weather alerts**, **NIFC wildfire perimeters**, **NASA FIRMS satellite fire detections**, **USGS earthquakes**, **USGS stream gauges**, **road/traffic (511 / TomTom)**, **NOAA space weather**, and **avalanche/RF-propagation** feeds.

Everything is switched on/off and tuned from the dashboard's **Data Feeds** page — enable a source, set thresholds and geography, and route its output per-mesh on the **Routing** page. Broadcast wording is tightened to fit a single LoRa packet without dropping the important details (e.g. affected towns on a weather alert).

### Native adapters vs. Central

Each hazard feed can get its data one of two ways, chosen per-feed with a `feed_source` switch:

- **`native`** — MeshAI fetches the source's public API **directly** (api.weather.gov, NIFC, USGS, NOAA SWPC, NASA FIRMS, TomTom, 511, avalanche centers). Self-contained — no extra infrastructure. This is the default and the original data path.
- **`central`** — MeshAI subscribes to **Central**, a companion service that pre-aggregates the same hazard data and republishes it as a **NATS JetStream** firehose, so many bots/nodes can share one set of upstream API calls and geo/severity filtering instead of each hammering the source APIs.

```yaml
environmental:
  central:
    enabled: true
    url: "nats://central.echo6.mesh:4222"   # NATS server (tailnet-gated, no auth)
    durable: "meshai-consumer"              # durable consumer name prefix
    region: "us.id"                         # server-side subject filtering
    connect_timeout: 10
  nws:   { feed_source: central }           # this feed comes from Central …
  fires: { feed_source: native }            # … this one is fetched directly
  # …one feed_source per hazard adapter
```

Native and Central are **mutually exclusive per feed** — flip any adapter between them independently. Two special cases: **`satpass`** is Central-only (there's no native predictor), and **`ducting`** (VHF tropo) is native-only (no Central equivalent). MeshAI keeps running whether or not Central is up: a **runtime** drop auto-reconnects (durable consumers resume where they left off), and a **startup** outage is logged and retried in the background rather than blocking boot — the LLM bot, both transports, mesh-health, and any `native` feeds all come up regardless; only the Central-sourced hazard feeds wait for Central to return. Feeds set to `native` don't depend on Central at all.

## Knowledge base (RAG)

Optional hybrid retrieval for survival, comms, medical, and technical Q&A.

- **Primary** — queries a **Qdrant** hybrid store (dense `bge-m3` + sparse, Reciprocal Rank Fusion) over a large curated vector set, via a networked TEI embedding service. Nothing is copied locally.
- **Fallback** — a local **SQLite** knowledge base (FTS5 keyword + `bge-small-en-v1.5` vectors) if the vector service is unreachable.

```yaml
knowledge:
  enabled: true
  backend: auto          # qdrant | sqlite | auto
  qdrant_host: "192.168.1.150"
  qdrant_port: 6333
  qdrant_collection: "recon_knowledge_hybrid"
  tei_host: "192.168.1.150"
  tei_port: 8090
  top_k: 5
```

The curated channel chatter your bot observes is used only as short-term *context* — it is never written into the knowledge base.

---

## LLM configuration

```yaml
llm:
  backend: "google"          # google | openai | anthropic
  api_key: "your-api-key"
  model: "gemini-2.5-flash"
```

Any OpenAI-compatible endpoint works for local models — point `base_url` at Ollama (`http://localhost:11434/v1`), LiteLLM (`http://localhost:4000/v1`), or Open WebUI.

## Running as a service

```ini
# /etc/systemd/system/meshai.service
[Unit]
Description=MeshAI
After=network.target

[Service]
Type=simple
User=your-user
WorkingDirectory=/path/to/meshai
ExecStart=/usr/bin/python3 -m meshai
Restart=always
RestartSec=10

[Install]
WantedBy=multi-user.target
```

```bash
sudo systemctl daemon-reload
sudo systemctl enable --now meshai
```

Every deployment is designed to survive a reboot; the dashboard's connection settings drive both transports.

---

## Playing nice with other services

- **advBBS** — MeshAI coexists on the same Meshtastic node; BBS protocol traffic (sync, RAP, mail) is auto-filtered (`bot.filter_bbs_protocols: true`).
- **MeshMonitor** — MeshAI reads MeshMonitor's auto-responder patterns to avoid duplicate replies, and uses its API as a mesh-intelligence data source.
- **MeshCore companion** — MeshAI attaches as its own companion identity so it can share the radio without evicting other companion clients.
