Walkthrough

The integration now links inverter child devices through inverter identifiers instead of registry IDs. The changes also update meter and battery diagnostic redaction, adjust device-registry tests, and revise the declared Home Assistant and test environment versions.

Changes: Device Relationships and Compatibility

Layer / File(s)	Summary
Use identifiers for device relationships custom_components/solaredge_modbus_multi/hub.py	Inverter registration and registry-ID lookups are removed. Meter, battery, and MMPPT parent relationships use the inverter identifier.
Update redaction and device tests custom_components/solaredge_modbus_multi/diagnostics.py, tests/test_der_storage.py, tests/test_hub_inverter_registration.py	Meter and battery diagnostics redact via_device. Device lookup assertions use identifier sets, and the inverter registration failure test is removed.
Update compatibility declarations README.md, hacs.json, .github/workflows/tests.yml, requirements-test.txt	The minimum Home Assistant version changes to 2025.9.0. The workflow uses Python 3.13, and the minimum test dependency version is lowered.

Possibly related issues

• WillCodeForCats/solaredge-modbus-multi#1166: The diagnostic redaction changes include parent-device identifiers for meters and batteries, which relates to the issue’s question about user data in diagnostics.

Possibly related PRs

• WillCodeForCats/solaredge-modbus-multi#1072: Both PRs change how child devices identify their inverter parent and whether the inverter is registered.
• WillCodeForCats/solaredge-modbus-multi#1165: Both PRs change inverter registration and parent relationships for meters and batteries.
• WillCodeForCats/solaredge-modbus-multi#1146: That PR requires Home Assistant 2026.10, while this PR changes the declared minimum to 2025.9.0.

The compatibility claim lacks guaranteed coverage on Home Assistant 2025.9.0. A minimum-version test is a useful follow-up.

Add a test job for Home Assistant 2025.9.0.

The current pytest job installs an unpinned pytest-homeassistant-custom-component range, so its resolved Home Assistant version is not fixed to the declared 2025.9.0 minimum. Add a job pinned to the plugin release for Home Assistant 2025.9.0. This adds compatibility coverage; it does not indicate a current production failure.
