#5490](https://github.com/springfall2008/batpred/issues/5490). +It provides no executable joint controller, regardless of where its shadow runs. + +The earlier import diagnostics remain a separate feature: +[PR #5486](https://github.com/springfall2008/batpred/pull/5486) neither implements +joint scheduling nor closes the new issue. + +## Implemented boundary + +This branch contains a bounded joint scheduler, synthetic regression cases, and +an opt-in **shadow** integration with native forecast data. It does not just report +an existing plan's excessive import: it searches different EV start/stop times +and home-battery demand/hold/charge sequences together. + +However, **it does not replace the executable native plan yet**. A fresh native +`Prediction` replays the candidate in both the central and PV10 scenarios. The +candidate is published only on the separate `predbat.joint_site_plan` entity; +`execution_enabled` and `enforced` are always `false`. The existing EV-slot signal, +inverter windows, active prediction object and kernel/cache are left untouched. + +This is intentional, not a claim of completed control integration. In particular, +the native executor joins adjacent charge windows even when their targets differ. +Prediction of a hold followed by charge is not enough to prove that the executor +will preserve that transition.

This PR can run without +the diagnostic PR: native replay then uses the upper rounding bound of saved +grid-power readings (0.5 W conservatism), not a claimed exact raw peak. No rate band is excluded +merely for being more expensive. A dated session expires: it is not a recurring +instruction to charge tomorrow regardless of the vehicle's whereabouts. + +Unknown options, non-finite inputs, missing forecasts and stale/future EV +observations are rejected. Arrival and departure are rounded inward to five-minute +steps, never granting energy before arrival or after departure. + +An arrival in the past means the expected availability interval has already begun; +the EV observation must still be fresh and the departure must still be future. +That remains an expectation, not confirmation of a connection. + +With `relay_entity`, the adapter reads the cached `on`/`off` value and its real +transition time. ON remains ON, even if it started recently; OFF time is elapsed +time rounded down, not cooldown remaining. A missing configured relay blocks the +calculation. Without this optional mapping the explicitly labelled legacy +assumption is OFF with minimum cooldown elapsed; it is never permission to energise. + +With `soc_entity`, a fresh cached observation replaces the dated SOC before checking +age. An unavailable configured entity does not fall back to stale dated data. +HA ISO timestamps and numeric strings are validated; unknown, non-finite, naive, +future and out-of-range data are rejected. The existing explicit EV manual SOC +setting retains precedence; it is not the domestic manual SOC target. Retaining +HA's `last_updated` separately from `last_changed` avoids equating an unchanged +value with an old observation. Cached HA freshness still does not prove physical +device freshness or connection, and no hardware refresh or service is requested. + +The initial integration supports one metered EV and one inverter, full-rate charge +and charge-freeze controls, no iBoost, and no manual mode/ceiling overrides. Domestic +manual minimum targets are retained as time-local SOC constraints and checked in +both the pure search and native replay; they are not converted to a permanent +reserve. Unsupported +cases have an explicit result rather than silently dropping the extra demand. +The solver uses an AC-equivalent model; hybrid PV conversion, power curves and +other native details can therefore reject a candidate during the independent +native replay. Such a rejection is **not** proof that no feasible plan exists. + +`control_model: deye_tou` is an explicit counterfactual scenario for commissioning: +it models full-rate charge, battery-first demand and hold with PV charging allowed +on an isolated copy. It does **not** change SK's capability flags or claim a hold +has been demonstrated on the installed firmware. Reports mark +`counterfactual_controls: true`, always keep `ready_to_activate: false`, and list +physical commissioning, coherent ToU configuration, executor equivalence and real +connection/permission as activation requirements. A successful hypothetical plan +is not evidence those requirements have been satisfied. + +The report separates `solver_grid_cost` from `solver_objective` (grid cost plus +the configured cycle-cost surrogate, less terminal stored-energy credit). +The terminal credit uses Predbat's existing battery value rate and scaling. +Native replay's `horizon_energy_cost` excludes wear, terminal credit and standing +charges, and reserves full EV power for every proposed on step, including the +final partly-filled step. These quantities are labelled in the configured minor +currency unit; subtracting one from another is **not** a measured saving. + +### Report states + +- `candidate`: a schedule was found and passed both native forecast checks; still + **not authorised or implemented for execution**. +- `native_rejected`: the candidate failed a native import, reserve or EV-threshold + check. Proposed windows are retained for analysis, never for control. +- `no_plan_found`: bounded search did not find a complete plan; not a mathematical + proof of infeasibility. +- `unsupported`, `invalid_input`, `error`: no candidate is published; any earlier + candidate is cleared. Raw configuration or exception values are not exposed. +- `disabled`: previously enabled shadow output is cleared on disabling the feature. +- `departure_passed`: the dated session is closed, with no automatic next-day + renewal. A later SOC observation is not proof the target was reached on time; + departure-time evidence must come from the recorded history. + +No trustworthy connection sensor is invented by this feature. A future execution +path will need a separate real connection/session permission gate, including +staleness and disconnection handling. Expected arrival alone must never enable +the existing EV-slot signal. + +## Objective + +Choose EV charging and home-battery charging/holding/demand operation together, +using real household history, heating demand, solar forecasts and all eligible +tariff bands. The aim is a physically feasible, low-cost whole-site plan, not the +lowest import-price label for the car in isolation. + +Household demand is not silently shifted or shed. A fixed-rate EV remains an +on/off load at its actual rated power. The site import ceiling is distinct from +the inverter conversion, load-port and battery power limits. + +## Behaviour contract + +### Solar now, battery recovery later + +Given usable PV of 5 kW, household demand of 1 kW and a fixed 6.77 kW EV, +the planner may use approximately 2.77 kW of battery support when physically +available. It must account for subsequent PV recovery rather than insisting the +home battery be full before the car is allowed to charge. It must not pretend +the EV has modulated down to the PV surplus. + +### Night-time preparation and higher-price fallback + +Given insufficient PV, the planner may buy cheap electricity for the home battery +before the EV needs its support. Preparation must fit the real charging rate, +losses, available time, domestic reserve and import ceiling. + +When cheap hours alone cannot satisfy a departure target, the search includes +more expensive eligible hours before departure. Running out of cheap time is not +itself an unmet request. A genuine physical failure or a bounded search that finds +no plan must remain explicit; neither is repaired by clipping the import graph. + +### Household priority and battery hysteresis + +Given rising heating or household demand, the flexible EV/battery plan must adapt. +No household consumption disappears from the energy balance. Domestic reserve, +EV pause/restart thresholds and minimum off time are separate constraints, not +one arbitrary fixed reserve percentage. + +### Expected availability versus actual connection + +An expected arrival may establish a future EV energy need while the car is away. +It must not permit EV energy before arrival or authorise actual switching while +disconnected. Connection/session permission and expected availability are distinct +inputs. Unknown or stale EV state must not be silently treated as a confirmed +connection or a full battery. + +### Full-horizon accounting + +PV after a departure cannot meet an earlier EV deadline. It can affect the later +household battery value. Plans must preserve all energy, explicitly account for +losses and curtailment, and value terminal stored energy so a depleted battery +does not masquerade as a saving. + +## Physical and execution boundaries + +- Planning is not an instantaneous electrical protection mechanism. +- The inverter's actual demand/hold/charge behaviour matters. Do not assume a + battery-first inverter only supplies the portion above an import ceiling. +- A nominal inverter rating does not establish verified load-port, grid-passthrough, + battery/BMS or wiring capability. Those constraints need explicit configuration. +- No changes to hardware current limits, inverter mappings, polling frequency, + unrelated Home Assistant automations or protection settings are part of this fork. +- Native Predbat remains the planner, with the existing single EV executor. A + competing controller or an external solar-following service is not introduced. + +## Related upstream work + +- [#2449](https://github.com/springfall2008/batpred/issues/2449): import-limit modelling. +- [#5384](https://github.com/springfall2008/batpred/issues/5384): EV solar opportunity cost. +- [#5195](https://github.com/springfall2008/batpred/pull/5195): solar-led EV scheduling, + but its solar mode currently assumes charger modulation; it is not a drop-in + solution for a fixed-rate charger. +- [#3293](https://github.com/springfall2008/batpred/issues/3293): EV/battery concurrency. +- [#1199](https://github.com/springfall2008/batpred/issues/1199): rolling capacity + tariffs, a separate billing feature from a per-step site import ceiling. + +## Validation and release boundary + +Implementation and acceptance evidence must distinguish the isolated solver, +native prediction validation, HA publication and actual hardware execution. +Synthetic tests must include every case above plus reserve exhaustion, negative +prices, malformed inputs and disabled-feature regressions. A bounded search is +not a proof of global optimality or physical impossibility. + +The pure solver uses constant-power sub-intervals when a battery reaches its +reserve or capacity, or the EV reaches its requested energy or departure. +The EV is either off or at its configured fixed power in each sub-interval; +unused energy in a five-minute step is not fictitious power modulation. +The native replay deliberately reserves a whole on step, a conservative envelope +rather than a claim that its EV energy equals the solver's exact partial target. + +Run the focused tests from `coverage/` with the project's isolated Python: + +```bash +python ../apps/predbat/unit_test.py --test joint_site_core --test joint_site_native > joint-tests.log 2>&1 +``` + +The core tests check conservation independently of the solver's physics helpers +and compare tiny exhaustive cases against a separately written reference. +Native tests exercise a real `calculate_plan` call through the real solver and +replay, including positive candidates, native rejection, disabled operation, +error/publication isolation and untouched actuator signals. The 48-hour test +asserts a deterministic search-work bound and reports elapsed time; it does not +impose a machine-dependent wall-clock CI threshold.

The bound assumes +optimistic future charging and therefore only prunes states that cannot catch up; +it is not a replacement standing reserve. + +If a nominal candidate fails the two native checks, one additional bounded search +uses maximum nominal/PV10 load, minimum PV and PV10 charge-delivery assumptions. +Both native scenarios still check the resulting full-rate commands. Reports label +the chosen `solver_forecast_basis` and `search_attempts`; a conservative search +objective must not be presented as measured savings or a proof of global minimum. +This DEYE scenario assumes zero export and reports curtailment explicitly, without +changing the installation's export configuration. + +`proposed_discharge_power_limits` contains native DC-watt ceilings for limited +intervals; ordinary demand uses the existing full ceiling outside those intervals. +For these candidates, replay uses one fresh native Python `Prediction` per step, +setting its current-rate input while preserving the original SOC/temperature +curve maximum. The hot loop and kernel ABI are unchanged. The accumulated SOC +rounding bound is reported and considered at EV/manual thresholds. Existing +non-limited candidates still use whole-horizon native replay. + +With the separate local DEYE PR and a `deye_shadow` mapping installed, +`deye_command_check` also translates every candidate step through the real +inverter entry point against copied HA states. It reports table-repair and hold +commissioning hypotheses separately. Success proves only software translation +under those hypotheses: it does not confirm physical writes, current-limit +availability, firmware behaviour or automatic activation readiness. + The report separates `solver_grid_cost` from `solver_objective` (grid cost plus the configured cycle-cost surrogate, less terminal stored-energy credit). The terminal credit uses Predbat's existing battery value rate and scaling.

Native status-age watchdogs and electrical protections remain independent backstops. +#### Shared-template integration + +The combination of diagnostics, joint planning and the shared +`templates/deye_solarman.yaml` profile accepts `control_model: deye_solarman`. +It searches **only battery-first demand and full-rate charge**. Hold/freeze, +limited discharge, forced export, physical ToU-time and global-current writes +remain unsupported. Selecting this model does not turn those capabilities on. +The previous `deye_tou` counterfactual is still separate; its successful plan +cannot be applied through this template. + +In shadow, the actual custom `Inverter` profile, both verified source/SOC +sequences and all twelve cached control entities must validate before searching. +The model's capacity, reserve and raw power ceilings must match the actual +single-inverter inputs. Rate scaling must be 1.0 for this fixed-rate template; +it cannot execute a reduced or raised hardware rate merely because the model +was scaled. Non-matching inputs are rejected, not silently rewritten. +There is no fake DEYE object or `deye_local` fallback. The candidate passes both +native replays with the real no-freeze settings, retains manual domestic floors +and reserves full EV power per ON step. A bounded miss at a smaller beam may use +one reported retry at 512; this does not prove optimality or physical feasibility. +For capability subsets without hold, pruning retains both the cheapest and +highest-stored-energy label per EV-progress group within the same beam budget. +This avoids discarding the battery energy needed by a later fixed-power EV start. +The default all-mode search retains its existing ranking. + +Apply is still **default-off and independently commissioned**. Existing +`apply_verified` and `ev_executor_lease_verified` attestations, field-specific +180-second SOC/connection observations, exact permission/connection checks, +15%/25% hysteresis, configured OFF delay, read-only/calibration and competing +controller guards remain required. Installing this combination sets none of them. +Command validation rejects hold or power ceilings anywhere in the horizon, +including injected future actions. + +Dispatch uses the real `Inverter.adjust_charge_immediate` entry point and the +template's existing observed phase barriers. All six sources and six targets +must match before an EV lease is published. A rejected or partial service, +changed mapping, unavailable row or later observed-control drift revokes EV +authority without speculative recovery writes or falling through to legacy +execution.
