[RPi] Argon ONE V5 Case

Best to ask the add-on author via his GitHub repo, it's not something the core project created.

Have a look at the OLEDproc add-on:

OLEDproc Add-on

I just finished one little project. The work took me several weeks, but I believe it was worth it.

There are many OLED graphic displays on the market that are cheaper and look better than traditional (character) LCD displays.

I was sorry that so far these displays could not be used as a display for the Kodi multimedia center.

That is why I set myself the task of remedying this shortcoming. I am presenting the result of my work to you today.

The core of the solution is a new add-on called OLEDproc.…

So the first thing is activating the I2C interface. I think OLEDproc is adaptable for Argon ONE V5, but no noob solution.

Hey guys, I got the Argon ONE V5 case and OLED module today and had similar thoughts to OP (I also use the NVMe add-on but this just works straight out of the box). I got this working by using the Argon ONE Control add-on and Docker (add-on) with Python to run a script, where the I2C of the RPi5 is passed through to the Docker container (uses luma.oled).

1) Install Argon ONE Control add-on (enables I2C, fan, power button, temp controls)

In Kodi:

1. Add-ons → Install from repository → LibreELEC Add-ons → Program add-ons → Argon ONE Control → Install
2. Reboot to complete install

2) Verify I2C is enabled and can see the OLED module

SSH into LibreELEC and then run:

i2cdetect -y 1

You should see the OLED module at 0x3C

3) Install Docker Kodi add-on

In Kodi: Add-ons → Install from repository → LibreELEC Add-ons → Services → Docker → Install

4) Create the OLED script

Create a directory for the script and then create oled_stats.py:

mkdir -p /storage/oled
nano /storage/oled/oled_stats.py

Paste and save this:

# /storage/oled/oled_stats.py
import time, psutil, socket
from datetime import datetime
from luma.core.interface.serial import i2c
from luma.oled.device import ssd1306  # change to sh1106 if your panel uses that controller from PIL import Image, ImageDraw, ImageFont

# I2C bus 1, common OLED address 0x3C (change to your I2C address if not 0x3C)
serial = i2c(port=1, address=0x3C)
device = ssd1306(serial, rotate=0)
font = ImageFont.load_default()

def get_ip():
    # Works because the container uses --network host
    s = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
    try:
        s.connect(("8.8.8.8", 80))
        ip = s.getsockname()[0]
    except Exception:
        ip = "0.0.0.0"
    finally:
        s.close()
    return ip

def read_temp():
    with open('/sys/class/thermal/thermal_zone0/temp') as f:
        return int(f.read()) / 1000.0

while True:
    img = Image.new("1", device.size, 0)
    draw = ImageDraw.Draw(img)

    cpu = psutil.cpu_percent(interval=None)
    mem = psutil.virtual_memory().percent
    temp = read_temp()
    ip   = get_ip()
    now  = datetime.now().strftime("%H:%M:%S")

    lines = [
        f"Time: {now}",
        f"CPU: {cpu:4.1f}%",
        f"Mem: {mem:4.1f}%",
        f"Temp: {temp:4.1f}C",
        f"IP: {ip}",
    ]
    y = 0
    for line in lines:
        draw.text((0, y), line, font=font, fill=255)
        y += 12

    device.display(img)
    time.sleep(2)

5) Run the OLED container

Create and run the container by copying/pasting the below into your SSH session

docker run -d --name argon-oled \
  --restart=unless-stopped \
  --network host \
  --device /dev/i2c-1 \
  -v /storage/oled:/app \
  python:3.12-slim sh -c "
    apt-get update &&
    apt-get install -y --no-install-recommends libjpeg62-turbo-dev zlib1g-dev gcc python3-dev &&
    pip install --no-cache-dir pillow luma.oled psutil smbus2 &&
    python /app/oled_stats.py
  "

6) Interacting with the OLED container

• Container Logs: docker logs -f argon-oled
• Restart Container: docker restart argon-oled
• Stop/Start Container Manually: docker stop argon-oled / docker start argon-oled
• Remove Container: docker rm -f argon-oled

The --restart=unless-stopped flag makes the OLED container auto-start on every boot
The --network host flag is needed for the OLED screen to show the IP of the RPi5, and not the IP of the bridged docker network/container.

This is just very basic so I'm sure someone who actually knows what they're doing can create something more elegant.

The Argon ONE Control add-on is not required for the ONE V5 case, so you can skip this step. To enable the I2C bus, this line in the config.txt file is sufficient:

dtparam=i2c=on

Is it not needed at all? I never tested the power button on the V5 prior to installing the Argon One Control add-on but I was under the impression it was needed to allow the use of fan "curves" in relation to CPU and SSD/NVMe temps at the least. Does the ONE V5 fan turn on automatically based on some hardcoded temp value?

In any case its a lot of fun tinkering with the OLED screen to get it to display what I want it to:

not needed at all, because with V5

• IR receiver is not available
• FAN is controlled by kernel (connected to RPi5 fan connector) https://forums.raspberrypi.com/viewtopic.php?t=359778
• RPi5 power button is in use (no external MCU)

HarryH might be an idea to PR a correction to the add-on decription that indicates it's not required on v5.
