Area	What changed	PRs
Device fault repairs & ignored addresses	Actuator hardware anomalies surface as self-clearing Home Assistant repair issues (actuator_fault) and withdraw on recovery; ignored_addresses in the Options Flow silences faulty or unwanted devices and their repair issues.	#593, #611, #621

   • Translated Exceptions: All user-facing service and config exceptions (HomeAssistantError, ServiceValidationError) are mapped to translation keys under exceptions in strings.json and translations/en.json (feat: quality-scale Bronze + Gold (runtime_data, exception translations, stale devices, entity audit, docs); min core 2026.3 #321, fix(services): reject half-hour time zones in sync_time with a translated error #764).
   • Stale Device Management & Ignored Addresses: Cleanly prunes orphaned device entries at startup, supports user-initiated device removal via async_remove_config_entry_device (feat: quality-scale Bronze + Gold (runtime_data, exception translations, stale devices, entity audit, docs); min core 2026.3 #321), and allows silencing faulty or unwanted addresses via ignored_addresses (feat(options): silence faulty or unwanted devices via ignored_addresses option #611, fix(options): allow clearing ignored_addresses when omitted or empty in UI (#612) #666).

This integration is developed and maintained by the OpenWebNet-HA community.

Special thanks to:

• @anotherjulien for creating the original MyHOME integration and laying the protocol foundations.
• @GreenGrassBlueOcean for the v2 modernized architecture, gateway profiles, streaming proxy, and test suite.
• @xtimmy86x for crafting the frontend user experience, administration panel, cover calibration interfaces, and hardware diagnostics.
• @gdluck for outstanding engineering, invaluable ideas, and rigorous physical F461 plant measurements.
• @TheDarkWizard for crucial CEN+ wire address captures (KW8011), WHO 1001 diagnostics, and tireless real-world hardware testing across Living Now controls and MyHomeServer1 setups.
• @wave68runner for the authentic HL4684 touchscreen captures, BTicino 3550 thermoregulation sweeps, and tuner diagnostics.
• @Interstellar0verdrive for deep hardware actuator analysis, cover timing/concurrency mechanics, and platform extensions.
• @fedem95, @mantovanellimatteo, @lyubomirtraykov, and Cedric Rohou for key bugfixes, platform extensions, and community testing.
• @GianlucaCh for preserving and contributing the comprehensive 15-manual BTicino/Legrand specification archive (OWN DOC.zip), the official WHO_24.pdf Lighting Management specification, and CEN+ community automation references.
• @nicolacavallo84 for the iconic 70+ device plant captures and H4890 touchscreen multi-gateway traces that form our foundational CI replay fixtures.
• All community testers and trace providers whose real-world bus captures keep our test suite grounded in real hardware: "In traces we find the truth" — their traces prove again and again that we can only build reliable stuff when we get authentic user traces: @manfredgittmaier-afk, @eC0y0te, @simo72mast-lab, @lionelser, @caiosweet, @f18m, @marcob79, @xduss, @pakob81, @Depechie, @nce2704, @ricdijk, @imfreddie, @theveninjeremy, and @Yvan13120.

Finally had time to spin up that VM.
First impression is that what works works 😄
The transition covered everything, also all device names reverted to <device type> <APL>.

What does not work is:

• Advanced covers seem to be discovered as regular covers, even after seeing position aware OWN frames (I have Legrand 67557 everywhere)
• Dry contacts (I have a Legrand 3477 coupled with a mechanical lever to monitor if my garage door is open/closed)
• Lux Meters (I have a Legrand 048834 for motion/light sensing outdoors)
• The mechanism to lock/unlock APL endpoints (relies with WHO 14, I've used it occasionally but I'm not sure many people do)

With all that's been discussed today, I'm not sure what was supposed to make the cut at this stage though 😅
