Fixed: a negative cost rate no longer shades as if it stayed positive
The cost curve's filled area always closed at the bottom of the chart, so a
rate that dipped below zero (selling surplus back to the grid) kept shading
downward instead of shrinking toward zero, reading as if the cost stayed
positive the whole time. The fill now closes at zero itself, so the shaded
area actually shrinks as the rate crosses into negative and grows again on
the other side. Thanks to @TCWORLD (#411).
Fixed: the cost chip stays hidden when HA renamed its generated cost sensor
Home Assistant auto-generates a cost statistic named <meter>_cost when a price is
configured and no explicit one is set, and the card derived that same name to
read it. But that name is only a suggestion: the sensor's real identity is a
registry id, so re-registering the source meter (the integration re-added, a
device replaced) can leave the clean ..._cost id on a defunct entity while HA
quietly moves on to ..._cost_2 and keeps it there for good. The card now
prefers the exact mapping energy/info exposes (the same one HA's own frontend
reads), falling back to the derived name only when that map has nothing for a
given meter. Also: a dual-tariff grid whose flows share one live price entity
no longer reads as two prices and bails to "no price found", it dedupes to one
like it always should have. Thanks to the detailed write-up on #410.
Fixed: the home building now occludes correctly against its neighbours
The home prism always painted on top of every neighbouring building, whichever
was actually closer to the camera. Neighbours used to be pre-composited as one
faded group, entirely behind the home, so a neighbour genuinely standing between
the camera and the home still appeared behind it instead of correctly hiding
part of it. Every building now paints in one true depth order, home included, so
a nearer neighbour occludes the home exactly as it would occlude another
neighbour, and a farther one still sits behind it. Thanks to @vbtheory (#413).
How to test
Update to 2026.9.3-a2 (HACS pre-release) and check the card really shows a2 in HACS: a browser reload alone does not update the installed version.
- #411: a cost/hr curve that dips negative (selling surplus) should now shade toward zero instead of continuing to shade downward.
- #410: if your cost chip was hidden despite a price being configured in the Energy dashboard, check whether it now shows.
- #413: a neighbouring building genuinely between the camera and the home should now correctly occlude it when rotating.
