Exposing AMD Ryzen sensors on Proxmox VE / Debian

Debian (and Proxmox VE, which is Debian-based) does not read out AMD Ryzen hardware sensors (temperatures, fan speeds, voltages) by default. Installing lm-sensors and running its detection wizard exposes them.

Prerequisites

• Root/sudo access on the Proxmox VE or Debian host.

Steps

1. Install lm-sensors and build dependencies

apt install lm-sensors bison flex librrd-dev

2. Run sensor detection

sensors-detect

Answer yes to every prompt — this loads all the kernel modules the wizard identifies as applicable for the hardware.

Verify

sensors

Should now list AMD Ryzen temperature/voltage/fan sensors.
