Hey RyanPaesschesooneVintecc - oakctl doesn’t currently expose CPU, memory, or disk usage; for those you’d need to connect through SSH/ADB and inspect the device directly.
For networking, oakctl device setup can configure this during setup, but for an already configured device the supported route is agentconfd on the device: agentconfd configure <ip>,<netmask>,<gateway> for static IP, or agentconfd configure dhcp to revert to DHCP. Please avoid changing the NetworkManager profile manually.
The link-local address is the expected fallback when no DHCP server is available. We have also fixed an IPv4LL issue in newer OS releases; if you are on OS 1.20.5, please update before setting a static IP.

Thanks,
