📝 WalkthroughWalkthroughCoreCommandsMixin adds methods to enable, disable, or set manual override state. The methods use firmware-specific commands and avoid legacy commands when the requested state is already active. Tests cover successful commands, idempotent behavior, and error cases.

Review comments at @openevsehttp/commands_core.py:
- Around line 204-213: In the legacy override enable and disable flows, refresh
the charger status with force_status=True before each cached state check so
stale state cannot skip the required command. Update the state-check paths
around the “Cannot enable override” check and the corresponding check in
disable_override().
Review comments at @tests/test_commands.py:
- Around line 315-338: Update the `set_manual_override` test so steps 3 and 4
clear `caplog` before calling the method, preventing earlier log messages from
satisfying these assertions. Also assert that the v4 path makes the expected
POST with state “active” and the expected DELETE request.

📋 Review Summary
Tip
Review Status: 🟢 APPROVED
Change Type: 🛠️ Refactor / ⚡ Performance
Review Effort: 🟢 Low
Core Impact: Adds three idempotent manual override control methods (enable_override, disable_override, set_manual_override) with firmware-aware behavior for both modern (≥4.0.1) and legacy (<4.0.1) OpenEVSE firmware. All 497 tests pass and all 12 CI checks are green.

enable_override()(lines 192–229)- Firmware ≥ 4.0.1: delegates to
set_override(state="active")via HTTP API - Legacy firmware (< 4.0.1): calls
update(force_status=True)to refresh state, then sends$FERAPI command only if charger is sleeping (state 254). Idempotently no-ops if already active. - Proper error handling: raises
UnknownStateErrorif state unknown,CommandFailedErroron RAPI failure - Updates local

disable_override()(lines 231–267)- Firmware ≥ 4.0.1: delegates to
clear_override()(DELETE /override) - Legacy firmware: refreshes state via
update(force_status=True), sends$FSonly if not sleeping (state != 254). Idempotently no-ops if already sleeping. - Proper error handling mirroring

Defensive patterns observed:
- All legacy paths call
await self.update(force_status=True)before state checks — prevents stale cache from skipping required RAPI commands - Uses
.get("state")for safe dictionary access with explicit"state" not in self._statusguard - Version gating via
self._version_check("4.0.1")consistent with existing codebase patterns - No blocking I/O in async methods — all HTTP/RAPI calls properly awaited
- All legacy paths call

🔍 Diagnostic Lens Evaluation
1. Home Assistant Architectural Compliance
N/A — This is a standalone Python library (python-openevse-http), not a Home Assistant integration. No HA-specific patterns (DataUpdateCoordinator, entity caching, async_on_unload) apply.
2. Python 3.14 Runtime & Asyncio Edge Cases
✅ Clean — No unawaited tasks, no synchronous I/O in async methods, all await properly placed. Uses force_status=True parameter correctly for cache-busting. No asyncio.create_task without tracking.
3. Defensive Data Validation & Dictionary Traps
✅ Robust — Explicit "state" not in self._status checks before access, .get() for safe reads, version-gated firmware paths. Error types (UnknownStateError, CommandFailedError) are specific and actionable.
4. CI Diagnostics
✅ All Green — 12/12 checks passing including Python 3.13 and 3.14 build matrices. CodeRabbit review completed (auto-review skipped per repo config, manual invocation possible).
5. Prior Feedback (CodeRabbit)
The CodeRabbit review identified two items:
- Refresh charger status with
force_status=Truebefore each cached state check — Already implemented in bothenable_override()(line 204) anddisable_override()(line 243). - Clear
caploginset_manual_overridetest steps 3 & 4 — Already implemented in test file (lines 316, 332 for v4; lines 412, 427 for v2).
Both concerns are resolved in the current diff.
