This sounds like a good idea, especially as I run a pi zero 2, but then openplotter-i2c won't send any data.

Why do you say that? Where will it not send data to?

Here is how SignalK looks like normally:
And after disabling GUI/Autologin all data from i2c sources is missing:

I agree, you are quite right.
The I2C validation and consequently the data is missing. Maybe openplotter cannot start properly in this mode in which case my suggestion is worthless.

I encountered this as well. In my thinking, "headless" means the device does not run a desktop and that advantage of this is that you free up the resources that would normally be consumed by it. However, it appears that the I2C functionality will not run without a user being logged into the desktop.
I didn't start with the headless version of Openplotter, I just turned off the desktop through raspi-config. Does anyone know if the I2C will function with the headless version (and no desktop running)?
If the desktop is required, there is no headless operation IMHO.

As far as I remember, all the headless images do is proving an access point and several ways so log in. but the desktop is running in the background, and you can access it via vnc. And yes, i2c works.
