AquaLink v0.1.1

AquaLink v0.1.1

Changes since v0.1.0:

• tools: add scripts/release.py release pipeline + version.txt
• sensor: run DS18B20 at full 12-bit (0.0625 C); align threshold + docs
• test: add host-side pytest suite for the Python helpers
• scripts: drop PowerShell helpers, Python-only (verified on COM63)
• scripts: add cross-platform Python port-detect + serial monitor

Flash it (no build needed)

Prebuilt Thread firmware for the u-blox NORA-W40 (ESP32-C6). It's a single
merged image — flash it to offset 0x0 with esptool (pip install esptool):

esptool --chip esp32c6 write-flash 0x0 aqualink-thread-v0.1.1.bin

SHA256 (aqualink-thread-v0.1.1.bin):
5c08b8bb71ceebceb45e7eedd326ab055e6c6e2e4166965b82ee8f7c95483b73

Assets

• aqualink-thread-v0.1.1.bin — full flashable image (bootloader + partition
  table + otadata + app), Thread build. Flash to 0x0. This is the one most
  people want.
• aqualink-thread-v0.1.1.bin.sha256 — checksum sidecar.
• aqualink.bin — app-partition image only (for OTA / advanced use; not a
  from-scratch flash on a blank chip).

The Wi-Fi variant (--wifi) isn't prebuilt yet — build it from source
(see GETTING_STARTED.md).
Flashing the Thread image on a network without a Thread Border Router will
commission but not reach a controller — use the Wi-Fi build there.
