[OMV-Extras] Request: openmediavault-pwmfan plugin inclusion

Hi OMV-Extras maintainers,

I’d like to request inclusion of my plugin “openmediavault-pwmfan” for OMV 8.x.

Repo:

GitHub - Ashcal9669/openmediavault-pwmfan: OpenMediaVault 7 PWM fan controller plugin for Raspberry Pi

OpenMediaVault 7 PWM fan controller plugin for Raspberry Pi - Ashcal9669/openmediavault-pwmfan

github.com

Package:

openmediavault-pwmfan 8.0.1-2 (arm64)

APT test repo:

deb [trusted=yes] https://ashcal9669.github.io/openmediavault-pwmfan ./

What it does:

PWM fan control via sysfs on Raspberry Pi; integrates with OMV Workbench UI and stores config in OMV confdb (with /etc/openmediavault/pwmfan.json for runtime).

Integration details:

- systemd unit: openmediavault-pwmfan.service

- OMV assets under usr/share/openmediavault/{confdb,datamodels,engined,workbench}

Hardware / Equipment used:

- PWM hub: Arctic Fan Hub

- GPIO pins: GPIO 32 = PWM, GPIO 34 = GND, GPIO 38 = TKG (tach)

- Fans: Arctic P8 PST PWM, Arctic P12 Max, Arctic P14 Max

- Power: dedicated 12V 1.5A supply to the hub/fans

Tested on:

8.0.6-2 (Synchrony), Raspberry Pi 5 Model B Rev 1.1, Linux 6.12.62+rpt-rpi-2712

If you need armhf builds, a signed Release, or packaging tweaks, I can add them.

Thanks,

Ashley Calili

Thanks for the feedback. It’s currently targeted at Raspberry Pi because it relies on PWM sysfs + tach

input that the RPi kernel exposes, but it’s not inherently RPi‑only — any system with /sys/class/pwm

(and a supported hwmon tach) would work.

That said, I agree it shouldn’t run on unsupported hardware. I can add guards so it’s safe on non‑RPi:

- systemd `ConditionPathExists=/sys/class/pwm` (and/or hwmon pwm/tach)

- runtime detection (exit cleanly if no PWM/tach is found)

- optional UI warning if hardware is missing

If you prefer to make it effectively RPi‑only, I can add a package dependency on the RPi kernel/

firmware package so it won’t install elsewhere.

Also yes, it’s built and tested on OMV 8 arm64 only.

Let me know your preference and I’ll update accordingly.

#Update

I’ve packaged this plugin as Architecture: all so it’s installable on amd64 + arm64. It works anywhere /sys/class/pwm exists; if PWM hardware isn’t present, systemd Conditions skip the service and the UI shows a warning. Current release: 8.0.1-4.1.

Update: openmediavault‑pwmfan 8.0.1‑5

This release expands temperature sourcing for systems that use NVMe storage instead of HDDs. The plugin can now base fan control on NVMe

SMART temperatures (and combinations with HDD and/or CPU), so NVMe‑only systems are fully supported.

New temperature source options:

- NVMe SMART (smartctl)

- NVMe + HDD (max)

- NVMe + CPU (max)

- NVMe + HDD + CPU (max)

A dedicated NVMe devices list is included (e.g., /dev/nvme0n1).

If PWM hardware is not present, systemd Conditions skip the service and the UI displays a warning.

Architecture: all (compatible with arm64 and amd64 on OMV8).
