Config Flow does not open on HA 2026.6.2 - blank page when adding integration

[delatronfelix]

Home Assistant Version: 2026.6.2
AlphaESS Integration Version: 0.8.4
OS: Home Assistant OS 17.3

Description:
After installing the AlphaESS integration via HACS, the config flow does not open. When navigating to Settings → Devices & Services → Add Integration → Alpha ESS or directly via the URL http://homeassistant.local:8123/config/integrations/add?domain=alphaess, only a blank page is shown. No dialog appears.

Steps to reproduce:

1. Install AlphaESS integration via HACS
2. Restart Home Assistant
3. Navigate to Settings → Devices & Services → Add Integration
4. Search for "Alpha ESS"
5. Integration is not listed, or blank page appears when using direct URL

Investigation:
The custom_components/alphaess/ folder exists with all files present. The required dependency alphaessopenapi==0.0.17 was not found in HA's Python environment (/usr/local/lib/python3.14/site-packages/). Manual installation via pip install alphaessopenapi==0.0.17 did not resolve the issue as it installs to a different Python path than HA uses internally.

Logs:
No alphaess-related errors found in ha core logs. Only unrelated Apple TV errors present.

Expected behavior:
Config flow dialog should open and prompt for AppID and AppSecret.

Actual behavior:
Blank page, no dialog shown.

Heya @delatronfelix, are you able to delete and reinstall the integration via hacs and let me know if that fixes it?

the alphaessopenapi package should install on startup (when the hacs package is installed) but sometimes may fail todoso if pypi in unavailable or blocked

i dont seem to be having any issues, and i just uninstalled and reinstalled to test
