Pironman5 Path to the Oled Script

devstef · August 28, 2024, 8:11am

Hello,

In the instructions it says to edit the display on the OLED display I would like the script under: sudo nano /opt/pironman/main.py this file no longer exists.
Can someone tell me the correct path?
Or is this only for the Version 2

Thanks

To modify the OLED display of Pironman5:

1.The main code for controlling the OLED display and other functions is located in the pm_auto library’s pm_auto.py file:

github.com

sunfounder/pm_auto/blob/main/pm_auto/pm_auto.py

import time
import threading
import logging
from sf_rpi_status import \
    get_cpu_temperature, \
    get_cpu_percent, \
    get_memory_info, \
    get_disk_info, \
    get_ips, \
    shutdown

from .utils import format_bytes, has_common_items, log_error

from .fan_control import FanControl, FANS

app_name = 'pm_auto'

DEFAULT_CONFIG = {
    'rgb_led_count': 4,
    'rgb_enable': True,

This file has been truncated. show original

2.You need to clone the repository and modify the oled_handler() function in the pm_auto.py file:

github.com

sunfounder/pm_auto/blob/main/pm_auto/pm_auto.py#L191


      
                  'memory_used': memory_info.used,
                  'memory_percent': memory_info.percent,
                  'disk_total': disk_info.total,
                  'disk_used': disk_info.used,
                  'disk_percent': disk_info.percent,
                  'ips': list(ips.values())
              }
              return data
          
          @log_error
          def handle_oled(self, data):
              if self.oled is None or not self.oled.is_ready():
                  return
              
              # Get system status data
              cpu_temp_c = data['cpu_temperature']
              cpu_temp_f = cpu_temp_c * 9 / 5 + 32
              cpu_usage = data['cpu_percent']
              memory_total, memory_unit = format_bytes(data['memory_total'])
              memory_used = format_bytes(data['memory_used'], memory_unit)
              memory_percent = data['memory_percent']

3.After making your changes, reinstall pm_auto in the virtual environment:
cd ~/pm_auto
/opt/pironman5/venv/bin/pip3 install ./
4.Then restart the Pironman5 service:
sudo systemctl restart pironman5.service

Hi,

any advise how I can change the Units in the OLED display under home assistant ?

I use a small 128GB nvme, currently it show 0.0 / 0.1TB which is not useful, better would be in GB for me.

I already installed the addon which is working fine but I could not find a way to change the units there

louyo · December 7, 2025, 6:46pm

Well, AFAIK, you can get what you want but only if you hack the oled.py file. I did and now see 16/459 GB as opposed to 0/.4TB.

merlinfive · December 9, 2025, 9:49am

that’s what I thought but were can I find the oled.py /pm_auto.py file in home assistant ?

that’s the question

louyo · December 9, 2025, 10:34am

Well, I don’t run home assistant, but if runs on Linux, I would start with:
sudo apt install locate
sudo apt updatedb
locate oled.py
(that is what I did on Debian).

louyo · December 9, 2025, 10:49am

merlinfive · December 9, 2025, 3:11pm

yes under a linux distribution I found it too but home Assistant is quite different

that’s why I was hoping someone knows where to look

At the risk of stating the obvious, perhaps you forgot an /?

This works for me:

sudo find / | grep oled.py

nope but thanks for your effort , as I sad home assistant is quite different

Spf650 · December 10, 2025, 9:36am

Are you running HA inside a VM container or as a native OS?

louyo · December 10, 2025, 5:31pm

Good question. To satisfy curiosity, I installed the OS downloaded from raspberrypi. AFAICT, all is in docker container/images and the Pironman5 is an addin image. That would pretty much eliminate any hacking. Not sure.

Spf650 · December 10, 2025, 6:40pm

If I’ve understood your configuration correctly, but probably not, that would place your system files either side of that docker container, would it not? Possibly why you can’t find them, as you’re at the wrong side?

merlinfive · December 11, 2025, 8:58am

yes probably, that’s why I asked how to find the files

louyo · December 11, 2025, 12:36pm

If one pursues further by cloning the addon and reading the dockerfile, one sees that it clones https://github.com/pironman5.git and runs it. I suppose one could clone, edit the oled.py file and then create their own repository, etc. Probably an exercise in learning docker as well as a black hole to throw time. I am not a home assistant user, but would probably try the option of installing Debian, add the Pironman stuff and then install home assistant. Thanks for the lesson
