Omatach

Open Source

Version 1.0.0

A tachometer for your terminal. Omatach turns any Linux terminal into a live view of your car. Plug in an OBDLink adapter, pick it from the list, and the dashboard comes up with your engine's RPM on a dial, your speed, coolant, throttle and whatever else your car reports, updating many times a second.

Tested on Omarchy.

Requirements

Linux, and an OBDLink adapter for live data. No adapter yet? The built-in demo adapter lets you try everything first.

Features

Dashboard

A dashboard of live gauges in the style you prefer, from a braille dial to a bar with its recent history to big readable digits.

Vehicle Info

A vehicle info page with the VIN, protocol, and every module that answered.

Trouble Codes

Reads stored, pending and permanent faults and explains them in plain text from the Ford, GM, FCA and generic libraries built in, with the ability to clear codes.

Bring Your Own PIDs

Drop Torque-format CSV files in a folder and they appear in the picker, including computed values that combine other readings.

Record a Session

Press R to record a session as a CSV that opens straight in RevOBD2's chart view.

Demo Adapter

The built-in demo adapter drives a simulated car through a full drive cycle so you can try everything before you buy one.

Omatach is open source under the MIT license. Built on the same engine as RevOBD2. Issues and pull requests are welcome on GitHub.
