Patrick Schurig eb7d727d17 docs(optimiseur): liens vers le moteur sur Gitea, plus de renvoi à INTERFACE.md, « optimizer » en anglais 
Le miroir GitHub n'est pas encore synchronisé : les liens pointent sur git.etm-powersync.fr.
INTERFACE.md n'est plus dans le dépôt public : la forme des méthodes NymeaEnergy.* se lit sur
la box (JSONRPC.Introspect) ; GetOptimizerStatus n'est pas réservée à l'administrateur.
Orthographe anglaise unifiée : optimizer, optimization.

Tariffs

Tariff entered by the installer BETA

The installer enters the site's electricity purchase tariff; the box stores it.

  • Single rate: one price, all day.
  • Peak / off-peak: one price per period. The engine accepts several time ranges per period (for example off-peak at night and in the early afternoon); the ranges must cover the 24 hours with no gap and no overlap.
  • Prices in euro cents per kWh, all taxes included — the full price paid. A feed-in tariff can be added (0 if not entered).
  • Times are those of the box (its time zone), not of the phone.

In the app, the Tariff screen enters a single rate or peak/off-peak with one off-peak range. A tariff with several ranges is shown there read-only.

!!! note "Exposed, not used to decide" The engine exposes the tariff (display, local recording); it does not decide with it. Without an optimizer, control stays rule-based — see PV production forecast.

Dynamic tariffs ROADMAP

Arbitration on national tariff signals — France: Tempo (blue/white/red), off-peak and peak hours, dynamic offers; CO₂ optimization from the RTE eco2mix signal. Germany: variable tariffs, spot offers (EPEX), grid-responsive control of controllable loads under §14a EnWG; CO₂ optimization from SMARD (Bundesnetzagentur).

!!! note "Roadmap" None of this is available yet — in either market. Tariff signals and grid rules are national: ETM builds per market rather than translating one model across. That is why this page differs by language instead of being a translation.
