ESPHome 2026.6.2 released on 20-06-2026
ESPHome 2026.6.2 is out now. It fixes esp-idf tools path resolution to remove unnormalized-path warnings and resolves an RMT5 interrupt-priority conflict in fastled_base, improving build reliability and LED timing on affected hardware.
See the ESPHome GitHub release notes for the full changelog and installation details.
What’s in this release
- Resolve esp-idf tools path to avoid unnormalized-path warnings (fixes spurious warnings and potential path-related build issues).
- Fix RMT5 interrupt-priority conflict in the fastled_base component (stability and timing improvements for LED strips on affected ESP boards).
- Mark packet_transport encryption key as a sensitive configuration value so secrets are not exposed, and tighten the Home Assistant add-on to expose the device-builder public port only when port 6052 is explicitly mapped.
- Bundled esphome-device-builder bumped to 1.0.12 (packaged device-builder includes the latest fixes).
Upgrade notes
- No breaking API changes are noted; if you use the Home Assistant add-on and require the device-builder public port, explicitly map port 6052 in your add-on configuration. Check any packet_transport keys have been moved into secrets or marked sensitive as appropriate.
- If you need to revert, downgrade to the previous release tag via your usual installation method (use your package manager, Docker image tag, or the GitHub releases page to select an earlier release).
Tell the project about your experience with the update — report any remaining warnings or regressions on the ESPHome GitHub so they can follow up.
