This is fantastic news. I’m currently using HomeKit + Homebridge for all my smarthome stuff but I have HA Core running on a Proxmox host in the event I need/want to migrate. Apple continues to let me down year after year with their minimal Home updates but convincing my family to switch is a hurdle I’m not ready to tackle yet.
The Fn and Carl keys can be switched in software. I have a work-issued Lenovo with a similar layout. They can be soft-swapped in the BIOS. There’s also a desktop utility to do the same but I don’t know if they have a Linux version of it. I totally agree, the physical layout is annoying but it has a simple fix.
