Summary

• Disable the current date and current date/time setting entities by default using EPC 0x97 and 0x98 in the shared entity description helper.
• Other entities remain enabled by default.
• Fixes 1分ごとに現在時刻設定が行われる? #141.

Validation

• Core: tests/components/echonet_lite/test_const.py passed (13 tests).
• Core: targeted prek passed.
• HACS: compileall, JSON validation, and git diff --check passed.
• Core Home Assistant 2026.11.0 started in normal mode, initialized, and returned HTTP 200. It was stopped cleanly. The default-disabled behavior could not be visually verified because existing entity-registry entries retain their current disabled_by state; the default applies to new entries. HACS runtime verification is deferred until release on a separate machine.
• A device manufacturer-code read warning (EPC 0x8A) occurred during startup and was accepted as unrelated.

Dependencies

• Core equivalent: sayurin/ha-core@7531a74 (hems-master; no Core PR).
• Tested with pyhems d580de95915188024b713d473cee51d47316ac00. No pyhems change is needed; versions and dependency pins are unchanged.
