UniFi Dream Machine Pro: Fan control tool

udm-fan is a utility for interacting with the fans on a UDM-Pro over the network. It works by sending PWM fan control commands over the UDM's SSH management interface.

Installation

This crate can be installed via cargo with:

cargo install udm-fan

Usage

The following commands can be used to control the fans on a local UDM-Pro:

# Set the fans to half speed
udm-fan set 128

# Set the fans to full speed (with a custom IP address)
udm-fan set 255 --override-ip 172.16.11.5

# Bring the fans back to automatic control
udm-fan auto

Passwords can be provided through:

• The --ssh-password flag
• The UDM_SSH_PASS environment variable
• A .netrc entry with the hostname being the UDM's IP address
• The terminal at runtime
