Gammastep works and is the way to go for this functionality on Wayland as far as I know. There used to be a patched fork of Redshift to support Wayland, maybe Gammastep is even that fork with a new name.
Edit: I have only tried one shot mode on Arch Phosh which works. I haven't tried setting automatic temperature shifting.
