v1.0.1

v1.0.1 - Sensor Accuracy and Stability Improvements

Version 1.0.1 focuses on reliability, register correctness, and better sensor coverage after the 1.0.0 architecture release.

🚀 New Features

⚡ PV and Current Monitoring Expansion (#118)

• Added combined PV sensors for easier at-a-glance solar production monitoring.
• Added per-string PV current sensors for deeper diagnostics and array balancing checks.

🔌 Grid Connected Binary Sensor (#121, #125)

• Added Grid Connected binary sensor derived from inverter/grid telemetry.
• Improved derivation logic to use grid input frequency for more reliable state detection.

🐛 Bug Fixes

• Fixed battery register read handling to prevent incorrect battery values (#126).
• Corrected byte order for Charge First SOC Limit register writes (#123).
• Aligned Charge First hold register constants to protocol naming:
  • H_CHARGE_FIRST_SOC_LIMIT_AND_START_TIME → H_CHARGE_FIRST_SOC_LIMIT (reg 75)
  • H_CHARGE_FIRST_START_MINUTE → H_CHARGE_FIRST_START_TIME (reg 76)
  • H_CHARGE_FIRST_START_MINUTE_1 → H_CHARGE_FIRST_START_TIME_1 (reg 78)
• Added missing PV Charge Priority time entities to complete all 3 start/end pairs:
  • Charge First Start Time (reg 76)
  • Charge First Start Time 1 (reg 78)
• Corrected Reboot Inverter button lambda signature (#127).
• Ensured signed value handling when preparing write packets (commit e8601c2).
• Updated device group mapping for AC Couple Power T-Phase and Power Factor sensors (commit 09aad95).

🛠️ Improvements

• Aligned switch entity names and device groups with LuxPower app naming for better consistency (#124).
