SysResMon

System Resource Monitor

An easy way to monitor essential data from systems that are running "headless".

These systems, often Single Board Computers (SBCs) like the Raspberry Pi or home servers, are typically used for automation, media streaming, IoT purposes, or other continuous tasks. Since they run "headless," accessing their status or performance data can be more challenging compared to using traditional desktops.

For this project only few parts are needed.

Wemos D1 Mini

1.3" Oled Screen

Dupont cables

3D Printer

Using the your preferred filament color 3D print the case.

Case

Screen Clip

The source ino file is available here:

https://github.com/zangaby/SysResMon

Compile and upload the code using Arduino IDE.

Connect the screen to the Wemos as follows:

Place all the components in the case and close it.

The system_info.py is available in the project repository.

This script sends the data to the microcontroller.

Add a startup script to be loaded every time the system boots.

Allow the current user to access the USB device.

Create a service file /etc/systemd/system/sysresmon.service

Add a bash script that calls the python script

/etc/systemd/system/sysresmon.service

Update the permissions

Enable the service

Reboot to test

Few things that might be added to the project.

1. Add more monitored data;
2. Use different layout on the screen;
3. Add OTA update capabilities.
