Any way to get system information?

I’ll be adding a fan to my setup that will be controlled over canbus to an arduino, but would there be any way to get information like system temp from the OS into RealDash to output over canbus in Linux?

You mean like CPU temperature? Please be more specific with your requests.

Yes, cpu temp.

We generally try to avoid device inputs that are not available on all supported OS. While this could be implemented relatively easily for Windows and Linux, getting the CPU temp on Android and iOS reliably without rooting or jailbreaks is not generally achievable.
