OmenMon-Reborn

Welcome to OmenMon-Reborn — an active fork by seakyy, last updated May 2026.
The original OmenMon hardcoded the EC hardware layout for 2023 devices, causing severe issues (fans stuck at 100%, wrong temperatures) on newer and older HP Omen and Victus laptops.OmenMon-Reborn fixes this with a dynamic, XML-driven model database and a safe Heuristic Auto-Detector. If your laptop is unknown, it scans the hardware read-only and configures itself — no coding required.
What's new in Reborn?
| Feature | Description |
|---|---|
| Self-Healing | Unknown HP laptop? The Smart Fallback reads your EC registers safely and writes a working profile to OmenMon.xml. |
| Fan Bug Fixed | Ghost sensors TNT2–TNT5 that forced fans to 100% are now disabled by default for fan curves (still visible in the GUI). |
| Auto-Calibration Wizard | Click "Auto-Calibrate & Diagnose..." in the tray menu. OmenMon runs a guided 4-step fan stress sweep, scans the EC for fan-tachometer registers (16-bit LE, period-encoded, or direct-multiplier), applies the discovered layout to the live session, and copies a Markdown report to the clipboard for upstream contribution. The override survives a restart via a sidecar XML. |
-Probe CLI verb | OmenMon.exe -Probe generates a full WMI + BIOS + EC snapshot as Markdown — ideal for bug reports. |

OmenMon is a lightweight application that interacts with the Embedded Controller (EC) and WMI BIOS routines of an HP Omen laptop in order to access hardware settings, in particular to query temperature sensors and dynamically adjust fan speeds. It also helps you pick your favorite keyboard backlight colors and put the Omen key to better use.
OmenMon endeavors to replace all the useful functionality of the Omen Hub (a.k.a. Omen Control Center), the laptop manufacturer's application, without any of its numerous anti-features. It does not connect to the network at all, does not have advertising, built-in store, social-media integration and whatnot. It does only what you expect it to do and nothing else.
OmenMon is designed to run with minimal resource overhead. It comes with a clear and compact graphical interface, offering a great degree of configurability while also featuring an extensive command-line mode where various BIOS and EC read and write operations can be performed manually.
Most features are specific to HP devices with a compatible BIOS interface exposed by the ACPI\PNP0C14 driver but command-line Embedded Controller operations should work on all laptops.
