Test Compile - Build All Devices

Compile ESPHome firmware for every device in the repo using Docker. If a build fails, diagnose the error, fix the source YAML, and re-compile until all devices pass.

Workflow

Run all commands from the active repository worktree. Resolve its root once and use that path for Docker mounts; do not use a fixed machine-specific checkout path:

REPO_ROOT="$(git rev-parse --show-toplevel)"

1. Resolve the ESPHome Version

Use the ESPHome version pinned by the repository in .github/esphome.env. This is the same version used by CI and release builds; do not hard-code an older version in this skill.

ESPHOME_VERSION="$(sed -n 's/^ESPHOME_VERSION=//p' .github/esphome.env)"
test -n "$ESPHOME_VERSION"
ESPHOME_IMAGE="ghcr.io/esphome/esphome:${ESPHOME_VERSION}"

Keep these variables in the shell session used for the compile commands.

2. Compile Each Device

Run one Docker compile per device. Use builds/<slug>.factory.yaml, the same entry point CI uses, so the test matches what a release build would do.

docker run --rm \
  -v "$REPO_ROOT:/config" \
  "$ESPHOME_IMAGE" \
  compile /config/builds/<slug>.factory.yaml

Run devices sequentially because each compile is resource-intensive. Use a 10-minute timeout or block window when available so compiles are not treated as stalled too early. If a compile backgrounds, poll the terminal output until it finishes and read the result.

If the pinned image is missing, pull it first:

docker pull "$ESPHOME_IMAGE"

3. Interpret Results

• Success: output ends with Successfully compiled program or INFO Successfully compiled program.
• Failure: inspect ERROR lines and the file/line references around them.

Common failure categories:

• YAML syntax errors, including indentation and missing keys
• Missing !include targets or wrong relative paths
• Unknown component or platform
• Undefined substitution variables
• Type mismatches, such as a string where an integer is expected
• Missing packages: keys

4. Fix and Retry on Failure

When a device fails:

1. Read the full error output carefully.
2. Identify the failing file and line from the error message.
3. Open and read that file to understand context.
4. Fix the root cause in source YAML.
5. Re-run the same Docker compile command for that device.
6. Repeat until it succeeds, then move to the next device.

Do not skip a device or mark it as known broken. Every listed device must compile.

Fixes should target files under common/, devices/, or components/ when possible, not the builds/*.yaml wrappers because those are thin entry points.

5. Web UI Asset Note

The factory YAML bundles www.js via js_include. If the referenced JavaScript file is missing, compile will fail. Run this first when web UI assets may be out of date:

python3 scripts/build.py

6. Report

After all devices pass, summarize:

Compile results:
  guition-esp32-p4-jc1060p470  OK
  guition-esp32-p4-jc4880p443  OK
  guition-esp32-s3-4848s040    OK

Fixes applied:
  - <file>: <what was wrong and what was changed>

If no fixes were needed, show only the passing results.
