Was working on some older version but can’t remember the exact, any help is appreciated!
I don’t see I2C.
mount: permission denied (are you root?)
Detected Protection Mode is enabled. Disable Protection Mode in Info Screen.
no sda1 config found

This Configurator did it’s job. Perform a hard-power-off reboot now.
You will need to reboot twice total, once to place the files, and again to activate the I2C.
i have pulled the power from the plug many many times
I have enabled i2c with your addon, but the ArgonOne Active Linear Cooling addon is not working correctly. See logs below.

I don’t want to steal this thread too much but for anyone having problems feel free to try out my fork of the addon, i linked it further up the thread. Working fine for me.
Thanks for the tip! I am also seeing some strange things in the logs for your forked version:

How strange, it doesn’t see anything on your i2c bus at all. Are you sure the cables haven’t come loose?

Settings initialized. Argon One Detected. Beginning monitor..
2022-07-04_10:28:49: 40C - Level 2 - Fan 1% (Quiet Low)
This is my successful startup log, same versions as you
I reinstalled HA OS to my SSD, restored my previous backup, and re-enabled i2c. It is now working correctly.
I think something went wrong when attempting to enable port 22222 access using the HassOS SSH port 22222 Configurator add-on.
Couple silly questions. After enabling i2c, I installed this add-on and the fan went silent. Finally!
- Where is the config file that the settings are in? I don’t see it in my main configuration yaml.
- The add-on disappeared after I Started it. Is that expected? Now I can’t see its log or info.
Hi all,
I get the following error message when I want to check my configuration.yaml file.
Integration error: argon40 - Requirements for argon40 not found: [‘RPi.GPIO==0.7.1a4’].
What is wrong?
I got the active cooling addon working. Activated the I2C, rebooted twice. I can see that the fan is cooling.
But still this error message pops up.
having moved on to a mini pc I can no longer use this add-on…
I do wish we had something like this for an external fan though, as I see the need for that on my warmer attic in the summer 
however, I can not yet find a simple fan that allows me to switch in remotely, without having to also press a button on the actual fan itself…

I get this error in the log

I enabled i2C on my device, and I still get this error,
I would appreciate your help
I can see that the device is detected by the system, but some error occurred during communication. Try powering it off and back on. Not sure what the problem is, but it looks hardware related, not the software.
My installation is supervised
I removed your extension, and entered argonone-config in the terminal
I get an option to control the fan,
I tried uninstalling with the command
argonone-uninstall
But he writes to me that there is no argonone installation, but when I enter argonone-config I do get the option to control the fan, really strange…
It may be my problem with your extension, that this installation causes your extension to work incorrectly,
Do you have a solution how to remove it?
This will not work on debian.

What a disappointment 
Debian has support directly from Argon One.
True, but I want your extension that gives me an entity of the fan
