# Bug: supervisor_add_addon_repository redirect does not open pre-filled add repository dialog

[smcneece]

Description

The supervisor_add_addon_repository My Home Assistant redirect no longer triggers the pre-filled add repository dialog in the App Store. Clicking "Open link" on the my.home-assistant.io intermediate page opens the App Store correctly, but the add repository dialog does not appear and the repository_url parameter is silently ignored.

Steps to Reproduce

1. Click a badge link in the format:
   https://my.home-assistant.io/redirect/supervisor_add_addon_repository/?repository_url=https%3A%2F%2Fgithub.com%2Fsmcneece%2Fbattery-sentinel
2. The my.home-assistant.io intermediate page appears correctly — instance URL is shown, description reads "Show the add app repository dialog with a specific repository URL pre-filled in Home Assistant"
3. Click Open link

Expected Behavior

The Home Assistant App Store opens and a dialog appears with the repository URL pre-filled, ready for the user to confirm by clicking Add.

Actual Behavior

The Home Assistant App Store opens but no dialog appears. The repository_url parameter is not processed. The user has no indication that anything was supposed to happen.

Environment

Tested on two separate Home Assistant OS instances, both fully up to date:

	Production	Test VM
Browser	Firefox	Microsoft Edge
Installation	Home Assistant OS	Home Assistant OS
Core	2026.4.3	2026.4.3
Supervisor	2026.04.0	2026.04.0
Operating System	17.2	17.2
Frontend	20260325.7	20260325.7

Both instances have My Home Assistant configured. The intermediate redirect page displays correctly with the correct instance URL on both. Manual repository add via Settings → Apps → App Store → ⋮ → Repositories → + Add works correctly on both instances.

Notes

• The intermediate my.home-assistant.io page correctly describes the intended behavior, so the redirect type and repository_url parameter appear to be recognized by the service
• The failure occurs after "Open link" is clicked — the parameter is not passed through to or processed by the HA frontend
• This appears to be a regression; this redirect type has been used widely in add-on README badges and previously worked
