Since Clightd 5.0, Dpms API exposes 3 different plugins (priority-listed below):

Xorg
Wl
Drm

The API is the same for any of those plugins; but first 2 input parameters ("ss") meaning changes:

Xorg

$DISPLAY
$XAUTHORITY

Wl

$WAYLAND_DISPLAY
$XDG_RUNTIME_DIR

Support on wayland requires the compositor to implement org_kde_kwin_dpms protocol.

Drm

card number (found through ls /dev/dri/card*)
unused

When first param is left empty, clightd will fallback to "0", making it try to use /dev/dri/card0.
