Issue: Add Repository button may not trigger pre-filled dialog on recent HA versions

Description

The Add repository to Home Assistant badge button in the README uses the supervisor_add_addon_repository My Home Assistant redirect with the repository_url parameter pre-filled. On recent HA versions this redirect opens the App Store correctly but does not show the add repository dialog with the URL pre-filled — the parameter appears to be silently ignored by the HA frontend.

This has been tested on two separate Home Assistant OS instances (Core 2026.4.3, Supervisor 2026.04.0, OS 17.2) using both Firefox and Microsoft Edge, with the same result on both.

A bug has been filed with Home Assistant: home-assistant/my.home-assistant.io#698

Workaround

Use the manual repository add method documented in the README:

1. Go to Settings → Apps → Install App
2. Click the ⋮ menu (top right) and select Repositories
3. Click + Add (bottom right corner)
4. Paste https://github.com/smcneece/battery-sentinel and click Add

Can you help?

If the badge button does work for you — opens the App Store AND shows the pre-filled add repository dialog — please comment below with your HA version. This will help us determine whether this is a version-specific regression or something broader.
