ffunes/Omnibattery v1.3.0b5 on GitHub

[1.3.0b5] - 2026-08-08

Three-phase protection status sensor: adds sensor.omnibattery_three_phase_protection_status with disabled, active, limiting and degraded states. Its attributes expose the protection flag, currently limited batteries and their requested/assigned power, unassigned batteries, degraded phases and detailed per-phase telemetry/budgets; the custom dashboard includes the sensor in its diagnostics view.
Per-battery manual mode: adds an independent manual-mode switch for each battery, with persisted ownership and software charge/discharge controls, so selected batteries can be operated manually while the rest of the fleet remains under automatic control. Dashboard, diagnostics, translations and documentation are included.

Marstek active balancing moved to a Home Assistant blueprint: the integrated per-battery Active Balance Mode, its runtime state and dashboard controls were removed. The new blueprints/marstek_active_balance_blueprint.yaml runs one battery at a time through Battery Manual Mode, validates and cleans up every path, and migrates interrupted legacy runs safely. Normal voltage tapering, weekly full charge and passive monitoring remain integrated.
Marstek force-mode option names are now consistent: v2, v3, Venus A, Venus D and ESPHome expose None, Charge and Discharge. Existing ESPHome entities using the former lowercase spellings remain readable and writable during migration.

Marstek Venus E v2/v3 power caps could be overwritten or displayed as 2500 W: writes now use the app-supported 800/2500 W hardware values while the integration preserves and displays the user's lower software limit.
Manual charge/discharge sliders could exceed their configured maximums: the setpoint sliders now follow the live max_charge_power / max_discharge_power limits, and direct/manual commands are capped at the same boundary.
Smart Pre-discharge could block battery self-consumption during negative-injection windows: the runtime now holds the net grid target at 0 W instead of blocking all discharge, while preserving safety floors and preventing deliberate export; plans are automatically rebuilt after material battery-headroom changes so morning charging is reflected without manual Dynamic Pricing reevaluation.
