26a dont work. 26b WORKING! Thank!
Up and working again with v26b 
Thanks a lot for your support 
I’ve followed the official instructions Common Tasks - Operating System - Home Assistant to enable I2C but the module is not loaded on boot. No matter what I try. Any idea whats wrong? Versions are:
- Home Assistant Core 2022.6.6
- Home Assistant Supervisor 2022.05.3
- Home Assistant OS 8.2
@adamoutler1 While trying to run version 27, I still get that log:

But while running @Znany version, it runs fine.
Please try version edited by me for i2c-3: Dropbox - argonOne_edited.zip - Simplify your life (just add as local addon)
Do you have any idea why Version 27 would not run on my system? I’m running HA in Debian 11 as a Supervised Version. I activated i2C The official way.
Hi @adamoutler / @adamoutler1 !
at first thank you for this tremendous great support on this Pi case. I like it, very useful!
But dumb question still I have: why for fan you implemented the option to create an entity but for temperature only push it to the log? Why not also provide the option to create a sensor in HA? Then you´d (we´d) also have the case temperature value in same monitoring like where we have all already anyway all temperature values (maybe even also the ones from the Pi´s processor).
BR, Jochen

I don’t see I2C.

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 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.
