On the configuration page, the middle entry can create an Argon Fan Speed entity in HA that you can show on a dashboard.
I have this in my configuration yaml file for the cpu temperature.
sensor:
- platform: systemmonitor
resources:
- type: disk_use_percent
arg: /config
- type: memory_free
- type: processor_use
- type: processor_temperature
I can see temperature of my Pi4, but the add-on log tells me Error: Write failed when it tries to write values to Fan speed. Am I missing something here? Your help would be greatly appreciated.
THANKS!!

Maybe this issue is linked with This entity does not have a unique ID?
Please note the picture below is an example because my HA interface is in french so I took a picture showing the same warning on This entity does not have a unique ID? - Home Assistant
Can anyone one help with this issue?
@ adamoutler Are you still working on your add-on?
Amazing! I just installed your Add-on as a Local Add-on and what a relief when my Argon One Fan finally stopped!! I’m so thankful Znany! Very thankful!! So I guess @adamoutler1 should look into it for a future update. Thanks again!!!
EDIT: I just realized @adamoutler1 profile has been suspended… I hope he can get back to this forum soon and update his add-on. This add-on is just amazing and it needs to be updated with yours @Znany
Happy to hear that it helped 
Unfortunately, I am not pro, I just found workaround for issue so if there is somebody who is more experienced in building add-ons - it just requires to add ability to pick i2c device on configuration panel and everythinkg should work for everyone
Today I saw this in the log:
The Raspberry Pi GPIO integration is deprecated and will be removed in Home Assistant Core 2022.6; this integration is removed under Architectural Decision Record 0019, more information can be found here: architecture/0019-GPIO.md at 780ea1b180263fce7b08805c019dd580f3db6fe2 · home-assistant/architecture · GitHub
14:27:49 – (WARNUNG) Raspberry Pi GPIO
Does this will let this integration to not work anymore?
I read the thread on it, and it does sound like we’ll lose the ability to control our cooling fans.
It sounds like you can extract the rpi_gpio folder from the code and place it under the custom_components directory for now. Removal of GPIO Support
I’ve downloaded the code for 2021.12.10 so I can have a copy of the last working version of it.
I’ll have to figure out how, or if, I’ll continue on with the setup I currently have if that’s the case.
I believe the Argon One Active Cooling Addon doesn’t use the GPIO integration. It is running in it’s own docker container and drives the GPIOs directly (well directly via I2C).
@adamoutler (the writer of this addon) has a suspended account so it may be hard to ask him, if you are unable to confirm this by checking the code on Github.
I took a backup of the rpo_gpio integration just in case but I didn’t put it in the custom components folder. I upgraded to 2022.2 and the addon and fan seems to still be working fine for me. I was under the impression that the gpio functionality in HA core was going to be removed so that would mean add-ons like this should not be affected (this seems to be true at least for now)
I bit the bullet and upgraded to 2022.02 and this has so far been a non-issue.
I’m using this addon on an Rpi4 with an Argon Fan hat.
As @zoogara noted, this addon is communicating with the fan hat using I2C communication even though the fan hat is mounted on the GPIO header.
I altered my configuration to change the lowrange value so the fan would come on, and it did.
The fan stopped running once the lowrange value was reached.
I appreciate ya’ll testing the upgrade and seemingly confirm it did NOT break this addon. I too am running an Argon One which has a GPIO fan and it is confusing what the impact may or might not be. I’m gonna sit a bit and see if any more issues arise or not.
This is expected behaviour.
If you read my message again, you would see that it will be deprecated beginning from the release of 2022.6 and not 2022.2!
But what will happen to the code for the Button of the Argon One case:
binary_sensor:
- platform: rpi_gpio
pull_mode: DOWN
ports:
4: Argon One Power Button
GPIO has been removed because it’s too geeky.
HA wants to compete with Google Home or Apple
Hello @Znany,
I have upgraded my setup to run from SSD instead of SD card on HassOS on my Raspberry Pi 4, and while this add on worked perfectly fine on SD card, it is no longer correctly detecting the Argon case on I2C, so I suspect there is a need to change this in the code. Would you be able to point me to the potential fix, please?
Thank you!

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.
Do you have done all the things that are written:

In the information screen of the I2C Addon there should be four switches, the lowest should be switched off.
You should perform a shutdown of the Pi and then switch it off completeley, eg. pull out the USB-C cable. Then switch it on again, wait until it is started and switch it back off.
Then you are ready.
This is documented in the I2C Addon.
Everything works
Thank you very much for your patience
And for the simple and precise explanation
Thank you
Benjamin
