RMON – Raspberry Pi Terminal Monitor

RMON is a terminal-based system monitor for Raspberry Pi, inspired by nmon, with real-time display of CPU, memory, GPIO states, I2C devices, and more.

---

Features

• nmon-style system monitoring in the terminal (via curses)
• Per-core CPU usage and memory load shown with vertical bars
• Real-time status of GPIO pins (input mode, ON/OFF)
• I2C device detection using i2cdetect
• RaspMesh detection (checks for bat0 mesh interface)
• System metrics: CPU temperature, frequency, voltage

---

Requirements

• Raspberry Pi OS or similar (tested on Pi 3, 4, 5)
• Python 3.x
• Root privileges (sudo)
• Packages:
  • psutil
  • RPi.GPIO
  • curses (built-in)
  • i2cdetect from i2c-tools

---

Installation

sudo apt update
sudo apt install python3-pip i2c-tools
pip3 install psutil RPi.GPIO

Clone and run:

git clone https://github.com/aranbarri/rmon.git
cd rmon
sudo python3 rmon.py

sudo is required to access GPIO and I2C.

🔍 What It Monitors

Section	Metric
CPU	Per-core load with vertical bars
MEM	RAM usage percentage
DISK	Used and free disk space
NET	Sent/received bytes
SYS	CPU temp, frequency, voltage, mesh
I2C	Devices detected via i2cdetect
GPIO	States of GPIO pins (ON/OFF/N/A/RES)

GPIO pins monitored: BCM 4–27 (excluding 2 and 3, reserved for I2C)
