Argon One Active Cooling and Active Linear Cooling Addon

I’d need a unit to work with to support v5

I used to have the original case and loved your work. Just got a v5 and Pi5 and would really appreciate if you could help! Thanks in anticipation :slight_smile:

Welcome. Thanks. I don’t have a unit to work with. I wouldn’t mind supporting it but I won’t go out of my way to buy a unit just to add support.

My fan starts rattling really loud when below 10%, usually at 5%. Is there any way to implement a minimum fan speed? I’d like the fan to only start when the curve reaches 10%, and not try to run below that in order to avoid this excessive noise.

You have need of new fans. The fans shouldn’t rattle at all. Replace your fans. The lowest setting is barely audible.

Hi, thanks for your work.
I use from almost 2 years now.
I am migrating my installation of HomeAssistant from HAOS to docker on my rpi5.
There’s any way to install this addon as another container in docker?
thanks again

Yeah. You could repackage it. At the end of the day, just like the original argon one, it’s just a shell script. But you’d need to do it. I’m not supporting every configuration of hardware.

Can anyone help me:

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’m new to HA and struggling to get any of the options tow work on my RPi 5 / Argon One v5. The I2C configurator says that it’s done its job but I get errors when installing the cooling add-on. Here is what I get with the Argon One Active Cooling option (any ideas?):
