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

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.
