If the RTC can wake the system from hibernation, why can't it wake it from suspension?
The RTC wake powers on the system. But a suspended system is already powered up and kernel is in charge.
You need to use a systemd timer to schedule the wake up.
I've actually managed to get the RTC to work now (it needed another UEFI setting). I agree a systemd timer would be preferable in general, but I'm currently using suspend as a temporary substitute for hibernation until I get the latter to work (I have a separate thread on this).
