To get the fans working on your Pironman 5 Pro Max under Home Assistant OS, please try the following steps:

In Home Assistant, go to Settings → MOUNT → edit config.txt.

Add the following lines to the config.txt file:

```auto
dtparam=cooling_fan=on
dtparam=fan_temp0=40000
dtparam=fan_temp0_hyst=10000
dtparam=fan_temp0_speed=125

```

Save the file.After rebooting, the fans should work properly in Home Assistant OS

The reason this configuration is not in the main documentation is that Home Assistant OS is a headless (no desktop) system, so the 4.3‑inch DSI screen cannot function properly under Home Assistant OS. Additionally, dual NVMe display is not supported in that environment.

For these reasons, we have not included the Pro Max setup in the main Home Assistant OS guide.

However, we are now preparing a FAQ section specifically for Pironman 5 Pro Max on Home Assistant OS.

Thank you for your feedback – it helps us improve our documentation!
