auto-temp-gpiod-ctrl 0.1.0

Automatic temperature-based GPIO control for any libgpiod 2.x device.

Auto Temp GPIOd Control

Automatic temperature-based GPIO control for any device with libgpiod 2.x support.

Features

• Monitors all available temperature sensors using psutil
• Controls a GPIO pin based on user-defined temperature thresholds
• Displays a live, aligned temperature table in the terminal
• Optional test mode to simulate CPU load for thermal testing
• Clean startup/shutdown: always resets GPIO to OFF on exit

Requirements

• Python 3.7+
• libgpiod 2.x and its Python bindings
• psutil

Installation

Install via pip (recommended):

pip install auto-temp-gpiod-ctrl

Or from source:

git clone https://github.com/Anthony-s-Personal-Projects/orange-pi-zero-auto-temp-ctrl.git
cd orange-pi-zero-auto-temp-ctrl
pip install .

Usage

Run the controller with your desired parameters:

python -m auto_temp_gpiod_ctrl --on-temp 50 --off-temp 45 --soc-pin PH2

Or, if installed as a script:

auto-temp-gpiod-ctrl --on-temp 50 --off-temp 45 --soc-pin PH2

Parameters

• -i, --interval : Seconds between temperature checks and table refresh (default: 5.0)
• --soc-pin : SoC pin spec to control (e.g. H2, PH2)
• -c, --chip : GPIO chip device (e.g. gpiochip0 or /dev/gpiochip1, default: gpiochip0)
• --on-temp : Threshold to turn ON GPIO (≥ this temperature, required)
• --off-temp : Threshold to turn OFF GPIO (≤ this temperature, required)
• --test-mode : Enable heavy calculation simulation (for testing only)

Example

python -m auto_temp_gpiod_ctrl --on-temp 60 --off-temp 50 --soc-pin PH2 --test-mode

How it works

• Reads all temperature sensors and displays a live table
• Monitors the maximum temperature
• Sends GPIO output HIGH when max_temp ≥ on_temp, LOW when max_temp ≤ off_temp
• Optionally simulates CPU load if --test-mode is enabled
• Always resets GPIO to OFF on exit
