Documents the three new site options added in evcc-io/evcc#31072 (feature request: evcc-io/evcc#31071).

Draft — pairs with the code PR; will finalize once that lands.

Adds priorityStrategy (none/soc/deficit), priorityBasis (percent/energy) and priorityHysteresis to the site configuration reference, right after priority, with semantics, defaults (backward-compatible none/percent/0), and a YAML example.

Also documents:

  • the experimental flag: the Priority dialog (🧪) only appears with experimental features enabled, while the YAML config works regardless
  • heating loadpoints are excluded from the priority sub-ordering entirely (they always keep plain priority-tier ranking and don't force the energy-basis fallback)

English and German. English source only.

Add a priorityBasis section covering the percent (default) and energy
bases for the soc/deficit priority strategies, including the capacity
fallback, and note that the priorityHysteresis unit follows the basis
(soc-% or kWh).

priorityStrategy, priorityBasis and priorityHysteresis are now global
site options in evcc-io/evcc#31072 instead of per-loadpoint options.
Move their reference sections from loadpoints.md to site.mdx, rename
the default strategy from 'static' to 'none', and leave a pointer in
the loadpoint priority section.

…trategy

- priorityStrategy/priorityBasis/priorityHysteresis are experimental (UI gated by experimental mode, config works without it)
- heating loadpoints are excluded from priority sub-ordering entirely (EN + DE)
- heating loadpoints don't force the energy basis fallback (EN + DE)
Heating loadpoints and loadpoints without a known vehicle charge level keep
their plain priority rank. naltatis asked for the heating behaviour to be
written down when he excluded it in 60314ef; the unknown-soc case follows the
same code path. Also notes that the energy basis saturates above 99 kWh.
The energy basis is vetoed by any loadpoint that reports a charge level
without a known vehicle capacity, which includes chargers reporting soc
themselves, not only loadpoints without a vehicle. evcc now logs that and
publishes the basis in use, so document the fallback and that the deadband
is then read in soc-%.

Drops the 99 kWh saturation note: the gap is normalised against the largest
capacity in scope, so it no longer saturates. Folds the duplicated heating
wording into the existing note and mirrors everything into the German page.

The evcc implementation dropped the evcc.yaml fields (priorityStrategy,
priorityBasis, priorityHysteresis) in favor of UI/API-only settings.
Remove the yaml reference sections from site.mdx (en/de) and document
the feature where it semantically belongs: the loadpoints priority
section (en/de). Covers the experimental Priorities dialog, strategy
(none/soc/deficit), basis (percent/energy) with fallback behavior,
hysteresis deadband, heating exclusion, unknown-soc handling, and the
API/MQTT surface.
