Anyone who builds dashboards knows the annoyance of a status card demanding attention even when nothing needs fixing. The answer in the M3 Cards suite is a windows and doors card that collapses to a single line once everything is shut, and the change animates rather than snapping. That is the kind of detail that makes a whole suite feel considered, and the maker has said the goal was to make that card as easy as possible to use.
Version 2.6 brings the collection to 51 Material 3 style cards for Home Assistant dashboards, with five new ones by one count and seven by another. The additions include a check-in card with a slide gesture and an integrated timer that tracks elapsed time since arrival, a remote card with a ring-shaped D-pad for TV control, and router cards for LTE and 5G covering signal quality, throughput, data usage, modem and CPU temperatures, plus a restart button.
The way it fits together stands out. Tapping a value opens its curve and statistics in a bottom sheet instead of the default more-info dialog, with graphs spanning one hour up to 30 days, and pop-ups can hold any cards without a second card library. Haptics on button presses are an optional per-tile setting on Android, and animations and blur effects can be switched off. Installation runs through HACS by searching for M3 Cards.
Not everything is settled: a vertical swipe starting on a slider moves the slider instead of scrolling the page, and there is no fix yet, though the maker intends to try.
