Copilot · 2026-02-16T18:32:12Z

Addressing PR Feedback

Based on feedback from @SimonFischer04 and @DutchmanNL, implementing the following changes:

Fix German translation for lblPillowVersion (already correct: "Pillow-Version")
Remove unused jsonData from PillowVersion and ESPHomeDashboardVersion in jsonConfig
Implement Pillow version caching similar to ESPHome version pattern
Add PillowVersion to dashboard integration test
Refactor version fetching logic into reusable function
Add integration test for version fetching
Ensure clean log entries when fallback versions are used

Changes Made

Version Caching (commit `8ca4137`)

Added pillowVersions array to cache available versions from PyPI
Fetch versions once during adapter initialization in espHomeDashboard()
Store versions in _ESPHomeDashboard.pillowVersionCache state for persistence
Use cached versions in getPillowVersion message handler (no more repeated API calls)

Error Handling & Logging

Proper fallback to cached versions if PyPI is unavailable
Fallback to hardcoded versions if cache is also unavailable
Clear log messages at appropriate levels (warn/info/debug)

Configuration Cleanup

Removed unnecessary jsonData parameter from both ESPHome and Pillow version selectors

Refactoring (this commit)

Extracted version fetching logic to fetchAndCachePillowVersions() method
Simplified code and improved maintainability
Created comprehensive integration test (version_fetch_tests.js) that verifies:
- Versions are successfully fetched from PyPI
- Versions are cached in state for offline use
- Only stable releases are included (alpha/beta/rc filtered out)
- Versions are properly sorted (newest first)

Testing

Added PillowVersion: "Always last available" to dashboard integration test
Created dedicated version fetch integration test

Pull request overview

This PR adds the ability to customize the Pillow version used by ESPHome Dashboard, implementing a similar pattern to the existing ESPHome version selector. Users can now select from available Pillow versions via a dropdown populated from PyPI's JSON API, with fallback to hardcoded versions if PyPI is unavailable.

Changes:

Added PillowVersion configuration option with "Always last available" as default
Implemented PyPI API integration to fetch and filter stable Pillow versions (top 20)
Added version resolution logic that uses hardcoded 11.3.0 for "Always last available" or user-specified version
Added admin UI dropdown with autocomplete for version selection
Added translation keys (lblPillowVersion, hlpPillowVersion) across all locales
