Experimental ceiling-light candidate
Exact source commit: 526379f. Packaged Home Assistant manifest: 7.8.1rc2; source manifest remains 7.8.0.
- H60A1/H60A6: power and write-only front-panel brightness; qualifying Pact or exact reporter hardware/firmware enables RGB and 14/13 segments. H60A6 Pact 1/1 stays restricted. Kelvin, rendered segment brightness, scenes, music and effects remain unavailable.
- H601C: app-derived power, brightness, whole-device RGB and 2700–6500 K in 100 K steps, with basic readback verification. No segments or effects. H601C is distinct from H60C1.
- Audits fixed production parser registration, brightness-only exposure, reconnect authorization, post-write state races, invalid-request side effects, off-grid Kelvin and companion validation. Added retained-only brightness recovery and fail-closed unsafe appearance restoration.
Validation
Final make check passed: 3279 Python tests (79 skipped), 271 frontend unit tests, 34 browser tests, lint/type checks and generated-output verification. make package passed; release workflow verifies deterministic build and checksum. Independent read-only original-app, integration and final-release audits completed.
Install and owner qualification
Enable HACS beta versions, select this exact release, install and restart Home Assistant. Manually add or Reconfigure the printed exact SKU. Try power/brightness, enabled RGB/segments and H601C Kelvin transitions; compare visible output with HA state, then test reconnect/restart and restore the starting state. After a failure provide immediate redacted diagnostics with exact release, Pact/hardware/firmware and expected/observed result. Do not share unique device identifiers.
All three models remain Experimental. H601C has static-derived software evidence without physical qualification; H60A reporter fixture attribution is partial. Companion RGB is decode-only and full app-emitter-state restoration is unqualified. No stable support promotion or merge is implied.
