Dark mode is a new switch under Brightness on the screen's settings page, in
the Screen settings of ESP Screens and as switch.<screen>_dark_mode in Home
Assistant, so an automation can turn it on at bedtime. The screen changes
look at once, open cards and an alert included, and keeps it after a
restart. The design stays the same: a black page, graphite cards with a
hairline, soft white text, Home Assistant's state colours where they tell
something, and pastel card colours as deeper versions of themselves.
Every colour the firmware chooses now lives in components/smart_display/
theme.h: roles with a light and a dark value, the named card colours and
Home Assistant's state colours. The board profiles give widgets colourless
shared styles that theme.h fills, so a change of look refills those styles
and draws again what code painted by state. The light look is unchanged
apart from merges below one panel step. Dark mode costs 440 bytes of static
RAM on the CYD, and the LVGL tree of the host build is 416 bytes smaller; tests
keep colours out of every other file.
Comparing a screen that switched looks with one that booted in it also
found two older bugs, now fixed: a settings switch that was on showed its
knob at the left whenever its page was drawn, and the sun card's sunlit
area turned orange after a palette change. Firmware 0.2.54.

A binary sensor's tile and card now say what Home Assistant says for its
device class, such as Open or Closed for a door and Wet or Dry for a leak
sensor. The screen maps the class it already receives, with the same words
as the top bar and the history card; a test keeps both tables equal. A
history card still waiting for its answer no longer shows the previous
card's word.
Lights and binary sensors that are off turn grey, as in Home Assistant, and
a light without an icon of its own shows a crossed-out bulb while it is off,
on the tile and in the top bar. A chosen icon stays and turns grey.
