DSC-HUB 8.1.0

First full cut of the 8.x line after the v8.0.0-AlphaPi alpha — 102 commits.

Brain / SPA 8.1.0 · kit firmware train 8.0.0.0 (unchanged — no fleet reflash required by this release).

⚠️ Important: 8.0.0 AlphaPi cards cannot flash a kit

The 8.0.0 image shipped nine zero-byte kit firmware binaries. bake-firmware.sh falls back to writing empty placeholder .bin files when it cannot compile, and refuses to do so only under DSC_RELEASE=1 — which the 8.0.0 bake did not set. Anyone who flashed that card and ran the SPA USB-flash wizard got nothing flashable.

8.1.0 is the first image to carry real kit firmware. All eight roles are compiled from source and verified non-empty by a release guard that now aborts the bake if any binary is empty.

Role	Chip	Bytes
hub	esp32	1,283,136
control	esp32	1,381,600
pot1	esp32	1,134,704
pot2	esp32	1,134,688
heater	esp8266	476,960
heatmat	esp8266	476,960
humidifier	esp8266	476,976
dehumidifier	esp8266	476,976

Per-role sha256 provenance ships in kit-build.json on the card.

Build fixes behind this release

The kit firmware build had been dead for weeks — unnoticed, because the live hub firmware does not use the affected component and only the image bake exercises that path.

• dsc_fleet_setup did not compile on ESPHome 2026.6.5 — wifi::ScanResultsLock was removed upstream, WiFiScanResult::get_ssid() became a StringRef, and hub_mac_str() / panel_mac_str() were defined without header declarations.
• esp_http_client is excluded from ESP-IDF builds by default — so pure esp-idf targets (panel, probes) could not find the header while the arduino hub resolved it by accident. Now declared via include_builtin_idf_component().
• Kit binaries were located with a find -newer probe that assumed every compile relinks; a cached build is a success that rewrites nothing, so the bake aborted on valid binaries. Now scoped to the build path ESPHome itself reports.
• The thin-catalog cannalib service could not start on a card — neither its build context nor a prebuilt image shipped. Both now do.

Upgrade notes

• No fleet reflash is required. Expected firmware stays 8.0.0.0; the version only moves when the ESPHome source changes and a flash happens.
• Flash dsc-hub-8.1.0-arm64.img.xz with Raspberry Pi Imager (Use custom) for Pi 4 / Pi 5 aarch64, prefer Ethernet on first boot, then open #/setup.
• The thin catalog is opt-in: docker compose --profile thin-catalog up -d.

Assets

dsc-hub-8.1.0-arm64.img.xz is the flashable image. The uncompressed 2.6 GB .img is not attached — it exceeds GitHub's 2 GiB per-asset limit. Decompress the .xz, or rebuild with services/dsc-hub/image/bake-on-linux.sh.
