ledtop

Like htop (CPU and memory usage), but for your case LEDs. 😄

In this setup, memory is the left strip, CPU is the right strip.

Install

1. Install OpenRGB.
2. Run: $ pip install ledtop

Run

1. Launch OpenRGB.
2. Click the tab SDK Server and the button Start Server.
3. Run: $ python -m ledtop

Configuration

The config file location is defined by appdirs (ex: ~/.config/ledtop/config.toml) based on your OS, in TOML format. If no config file exists, running python -m ledtop will tell you where it should be.

To see your detected devices, zones and sensors, run python -m ledtop --info. Example:

$ python ledtop.py --info
--------------
 LED Displays
--------------
Device: 'B550I AORUS PRO AX' (id:0)
 - zone: 'D_LED1' (id:0)
 - zone: 'Motherboard' (id:1)

---------------------
 Temperature Sensors
---------------------
Device: 'acpitz'
 - sensor: '' (17°C)
Device: 'nvme'
 - sensor: 'Composite' (44°C)
Device: 'k10temp'
 - sensor: 'Tctl' (34°C)
 - sensor: 'Tdie' (34°C)
 - sensor: 'Tccd1' (45°C)
 - sensor: 'Tccd2' (42°C)
Device: 'iwlwifi_1'
 - sensor: '' (36°C)

Example configuration file:

[cpu]
device = 'B550I AORUS PRO AX'
zone = 'D_LED1'
leds = '1-21'

[memory]
device = 'B550I AORUS PRO AX'
zone = 'D_LED1'
leds = '42-22'
brightness = 20

[temp.ssd]
device = 'B550I AORUS PRO AX'
zone = 'Motherboard'
component = 'nvme'
leds = '1-2'

[temp.cpu]
device = 'B550I AORUS PRO AX'
zone = 'Motherboard'
component = 'k10temp'
sensor = 'Tctl'
leds = '3-5'

There are three section types with the following options:

Section: cpu

Section: memory

Section: temp

If you want more than one display of each type, name them like:

[cpu.1]
...
[cpu.2]
...

Colors

Default LED colors are the same as htop. For CPU usage the color key is:

• Blue: low priority processes (nice > 0)
• Green: normal (user) processes.
• Red: kernel processes.
• Yellow: IRQ time.
• Magenta: Soft IRQ time.
• Grey: IO Wait time.

Memory:

• Green: Used memory pages.
• Blue: Buffer pages.
• Orange: Cache pages.
• Grey: Free (unused)
