2026.6.2.b1 - Smart polling beta

This beta introduces a smarter Modbus polling strategy that reduces the number of requests by grouping contiguous registers into shared block reads.

Highlights

• Added smart polling for contiguous due registers
• Reduced unnecessary Modbus requests by reading grouped registers in shared blocks
• Kept single-read fallback behavior for robustness
• Improved debug logging for block reads, single reads, and failover reads
• Simplified polling configuration from four tiers to two:
  • high
  • low
• Added backward-compatible migration for existing polling settings
• Updated register definitions and translations to match the new polling model
• Improved coordinator resilience for unexpected total_increasing regressions
• Guarded number writes when coordinator data is still empty

Observed result

In runtime testing we observed:

• Full refresh cycle: due=54, requests=27
  • about 50% fewer Modbus requests
• Fast polling cycle: due=15, requests=9
  • about 40% fewer Modbus requests

The biggest gains come from grouping previously separate reads, especially for:

• battery-related sensors
• AC-related sensors
• schedule registers
• version information
• power-setting registers

Notes

This is a beta release intended for testing and validation before final release.
Feedback about stability, polling behavior, and device compatibility is very welcome.
