Hotfix for a regression introduced in 2026.9.5. Update if you are on it.
Fixed: a live power counted twice
2026.9.5 taught the card to read the live power sensor in all three shapes Home Assistant has used for it, so that a dashboard written in the newest one stopped reporting no sensor at all. It read them all at once, and that is wrong: the shapes are alternatives, not additions.
A source states its live power once. A dashboard that carries two of the shapes names those same watts twice, often under two different entity ids: a signed net sensor at the top of the source, and in power_config the from/to pair that net sensor is the sum of. Both were being summed, so a grid or a battery wired that way showed exactly double what was flowing (reported in #444).
The cascade is exclusive again, in the order each family has always had: a battery takes its directional pair over its net sensor, a grid and a solar source take their net sensor first, and the newest shape's array is read only by a source that states nothing at its top, which is the configuration 2026.9.5 set out to support. Several entries of that array are several meters and still add up.
Six tests pin it, five of which fail against 2026.9.5, and the fix was checked against a real dashboard carrying both shapes: three sensors were being summed where one describes the power.
Nothing else changed. Everything in 2026.9.5 is unchanged.
Thanks to @kotana for reporting it within hours of the release.
