HyperHDR integration broken after Home Assistant Core 2025.6.1 update #38

After updating to Home Assistant Core 2025.6.1, the HyperHDR integration no longer works.

Problem Description
• The integration shows a warning icon (!) and is unavailable.
• Removing and re-adding the integration via ip_address:19444 results in: “No devices found”
• HyperHDR is still running correctly on the Raspberry Pi and fully functional via its web interface.
• No changes were made to the HyperHDR configuration or network.
• This issue started immediately after the 2025.6.1 core update.

Troubleshooting Performed
• Restarted both Home Assistant and the Raspberry Pi running HyperHDR — no effect.
• Verified that port 19444 is reachable and the API is responsive.
• Reinstalled the integration — still no devices found.
• Restored a full backup of Home Assistant from before the 2025.6.1 update, and everything works again — HyperHDR is detected and controllable.

System Information
• Home Assistant Core Version: 2025.6.1 (broken)
• Home Assistant Core Version (working): 2025.5.x

Expected Behavior

The integration should detect and connect to the running HyperHDR instance like it did before the update.

Additional Notes

It seems something introduced in Home Assistant Core 2025.6.1 is breaking the discovery or communication with HyperHDR. Since rolling back fixes it immediately, it’s likely a regression or breaking change.

Please advise.
