Omni Console

The serial monitor that decodes industrial protocols.

Watch, decode and drive serial traffic in real time — Modbus, DLMS, M-Bus, IEC 62056-21 and MASS — with line sniffing, an online device library, Python flow automation and AI control. One fast desktop app for Windows & Linux.

Omni Console is a fast, cross-platform serial-port monitor and protocol decoder for engineers working with meters, drives, PLCs and field instruments. Capture or sniff a live line, decode a dozen industrial protocols into readable values, build and send valid frames, automate with Python-powered flows, and even hand the controls to an AI agent — all in one app, on Windows and Linux.

✨ Why Omni Console

Three things set it apart from a plain terminal or a single-protocol poller:

• ⚡ Real-time and byte-accurate. Coalesced RX with precise timestamps, pause/resume, RX/TX filtering and instant full-text search across the whole trace — backed by a fast SQLite store.
• 🔍 It decodes, it doesn't dump. Protocol-aware decoding turns raw bytes into readable frames — Modbus register maps, DLMS OBIS, M-Bus DIF/VIF, request ↔ response pairing and exception decoding.
• 🤖 Automate & integrate. Drive the bus with visual flows and Python, let an AI agent operate the app over MCP, or reach a remote edge device's serial port over SSH.

🧩 Protocol coverage

Twelve protocols decode automatically — point Omni Console at any line and read labelled frames instead of raw hex. Five go all the way to named, unit-aware engineering values, with command builders for three of them.

Full value parsing + frame builders

Protocol	Decode	Command builder	Value parsing
Modbus (RTU · ASCII · TCP)	✅	✅	✅
DLMS / COSEM (HDLC, OBIS, AES-GCM, HLS)	✅	✅	✅
M-Bus (self-describing DIF/VIF)	✅	✅	✅
IEC 62056-21 (Mode A–E sign-on)	✅	Quick-send	✅
MASS (Turkish metering standard)	✅	Quick-send	✅

Frame & field decoding — framing, addresses, function codes and CRC checked and labelled

📚 Online device library

Omni Console ships with an online Modbus device library. Browse it in-app, load a register map (fetched on demand and SHA-256 verified), and every register comes back named, typed, scaled and unit-aware — no more transcribing register tables out of a PDF.

The catalogue is open and lives in modbus-library/: 144 maps across 27 vendors, including Moxa, Advantech, Carlo Gavazzi, Entes, Eastron, Circutor, ABB, Lovato, Accuenergy, Janitza, Schneider, Socomec, Chint, Finder, Klemsan and more.

Map format & contributing a device

Each device is one plain-TOML file named <vendor>-<model>.toml:

vendor = "ABB"
model = "A43/A44"
description = "3-phase energy & power quality meter — per-phase V/I/P/Q/S/PF, frequency, 64-bit energy import/export (FC03, Big-Endian)."

[[registers]]
address = 23296        # raw Modbus register address (as on the wire)
type    = "u32"        # u16 · s16 · u32 · s32 · u64 · s64 · f32 …
name    = "Voltage L1-N"
unit    = "V"
scale   = 0.1          # engineering value = raw × scale

[[registers]]
address = 23340
type    = "u16"
name    = "Frequency"
unit    = "Hz"
scale   = 0.01

Add word_order = "little" on a register when a multi-word value isn't big-endian (MSW-first).

Add your device — the catalogue grows by pull request, and one map helps everyone decoding that meter:

1. Fork this repository.
2. Add modbus-library/<vendor>-<model>.toml (lowercase, hyphenated).
3. Fill in vendor, model, description and the [[registers]] table, citing your source datasheet in a top comment.
4. Open a pull request. Once merged, the map appears in-app for everyone.

🤖 AI control (MCP)

Omni Console embeds a local Model Context Protocol server, so an AI agent can operate the instrument alongside you — opening ports, sending frames, reading & decoding the trace, and building sequences, flows and device maps. The agent and the GUI share one port and one trace, so you both see every byte live.

Point any MCP client at the local endpoint:

{
  "mcpServers": {
    "omni-console": { "url": "http://127.0.0.1:9009/mcp" }
  }
}

• Bound to 127.0.0.1 only — no cloud, a single-user local control plane.
• MCP Streamable-HTTP transport · enabled by default (toggle in settings).

🚀 From install to decoded traffic in minutes

1. Download & open — install on Windows or Linux and launch. No account needed.
2. Connect a port — pick a port and baud (or auto-negotiate). Sniff a live line, or reach one over SSH.
3. Watch it decode — traffic streams in, decoded per protocol. Automate it with flows, or let an AI agent take the wheel.

Installed copies check for signed updates and refresh themselves in place — you're always on the latest build.
