meshdb

A lightweight Python library for storing Meshtastic node, telemetry, and message data in per-node SQLite databases.

## Installation

You can install meshdb directly from PyPI using pip:

pip install meshdb

Or install from source within a virtual environment:

git clone https://github.com/pdxlocations/meshdb.git
cd meshdb
pip install -e .

Or install via Poetry:

poetry install

Quick Usage Example

Set a default database path and handle incoming packets:

from meshdb import handle_packet, set_default_db_path

set_default_db_path("./data")

packet = {
    "from": 12345678,
    "rxTime": 1700000000,
    "decoded": {
        "portnum": "NODEINFO_APP",
        "user": {"longName": "TestNode"}
    }
}

handle_packet(packet, node_database_number=12345678)

Network Connection Options (Serial/TCP/Virtual Node)

meshdb now includes a connection helper that supports:

serial (default)
tcp
udp virtual-node mode

import meshdb

conn = meshdb.connect(
    transport="udp",
    virtual_node=meshdb.VirtualNodeConfig(
        node_id="!89abcdef",
        long_name="MeshDB Virtual Node",
        short_name="MDB",
        channel="LongFast",
        key="AQ==",
        mcast_group="224.0.0.69",
        mcast_port=4403,
    ),
)
print(conn.transport, conn.owner_node_num)

When receiving packets from udp, use meshdb.normalize_packet(packet, "udp") before passing to meshdb.handle_packet(...).

CLI Listener

You can run:

meshdb
meshdb --db ./data --transport tcp --tcp-host 127.0.0.1:4403
meshdb --transport udp --node-id !89abcdef --channel LongFast

This connects to the mesh, listens for new packets, and persists them into the owner database until you stop it with Ctrl+C.

The CLI is configured with explicit arguments rather than environment variables. For udp transport, you can also pass:

--long-name
--short-name
--hw-model
--key
--mcast-group
--mcast-port

Owner Database

meshdb stores data per owner node. The owner_node_num value selects which owner's SQLite database and table set you are reading or writing.

That matters because the same remote node can appear differently depending on which local node observed it. Signal, last-heard time, hops, and even the available node list are owner-specific.

If you have a live Meshtastic interface and want to import its current NodeDB snapshot, you can do:

import meshdb

count = meshdb.sync_nodes_from_interface(owner_node_num, interface)
print(f"imported {count} nodes")

Lookups in Code

import meshdb

meshdb.set_default_db_path("./data")

node = meshdb.get_node(12345678, owner_node_num=12345678)
battery = meshdb.get_node_metric("TestNode", "battery_level", owner_node_num=12345678)
