What's Changed

• fix(arch): ARM64 native runner — fix aarch64 Docker manifest, drop 32-bit by @atbore-phx in #141

ARM64/aarch64 Build Fix

The v2.0.0 release introduced an ARM64 regression where the Docker image was mislabeled as linux/amd64, preventing installation on ARM64 hardware (Raspberry Pi, ODROID, etc.). This was caused by the upgrade of the home-assistant/builder action to v2026.03.2, which no longer handles cross-platform manifest labeling.

The fix uses a native ARM64 GitHub Actions runner (ubuntu-24.04-arm) for aarch64 builds, ensuring the correct linux/arm64 platform manifest.

32-bit architecture support (i386, armv7) has been dropped — GitHub provides no native 32-bit runners, and the home assistant builder action cannot cross-compile because it doesn't rely on QEMU anymore.

Full Changelog: v2.0.0...v2.0.1

What's Changed

• Added support for cross-midnight charge (start_hr, end_hr) and reserve (batt_reserve_start_hr, batt_reserve_end_hr) windows, for example 23:00-05:00. Equal start and end values remain invalid.
• Added opt-in MQTT support to the add-on with configuration keys for broker, credentials, topic prefix, and Home Assistant discovery controls.
• Added MQTT runtime topics for availability, state snapshots, error reports, command intake, and per-command acknowledgement payloads.
• Added Home Assistant MQTT Discovery publication so sbam entities are created automatically when MQTT discovery is enabled.
• Added MQTT command handling for trigger_now, pause, resume, force_charge, and set_defaults.
• Added Home Assistant MQTT slider selectors for force-charge target and pause duration with explicit send-button actions, including an explicit uncapped full-charge override payload ({"target_pct":100,"ignore_max_charge":true}).
• Added serialized schedule execution through a single runner queue so cron ticks and MQTT command intents do not race each other.
• Added extensive tests across MQTT client behavior, command parsing, discovery payloads, schedule runner lifecycle, cron wiring, and config precedence.
• Changed add-on startup behavior to auto-fill MQTT broker host/port and optional credentials from Home Assistant service data only when MQTT is enabled and broker is not manually set.
• Changed precedence behavior so manually configured broker, username, and password are preserved over auto-filled Home Assistant service values.
• Changed documentation coverage with expanded add-on setup guidance, MQTT usage notes, topic and payload references, command examples, and migration notes.
• Enhanced non-blocking schedule execution in case of errors or long-running operations, with serialized command and cron execution through a single runner queue.
• Extracted and Improved Fronius decision/classification helper. Author: @mvanhorn
• Clarified release scope: set_reserve remains intentionally unsupported in v2.0.0.
