When an admin changes their password the first_login flag was never
cleared, so the UI would keep prompting for a password change on
every subsequent login.
Write KEY_ADMIN_FIRST_LOGIN = b"0" inside the same write transaction
before the password key to satisfy ekv's lexicographic ordering
requirement ("admin/first_login" < "u/…/pw").

The HLW8012 outputs two 50% duty-cycle square waves whose frequencies are proportional to active power (CF) and current/voltage RMS (CF1). Two RP2040 PIO state machines measure the HIGH half-period of each signal by counting down a 32-bit register at 2 clock cycles per loop iteration, then pushing the result to the RX FIFO asynchronously. The driver (Hlw8012Driver<'d>) ties to PIO0 SM0 (CF) and SM1 (CF1). Calibration multipliers are pre-computed from the datasheet §3.2 formulas using the µs/unit convention of the Arduino reference library: value = multiplier / T_half_µs / 2. Circuit defaults (config.rs): GPIO 8 = CF (active power) GPIO 9 = CF1 (current/voltage RMS) GPIO 10 = SEL (LOW = current mode, HIGH = voltage mode) R_sense = 1 mΩ, V_ratio = 1881 (4×470 kΩ + 1 kΩ divider) A minimum-frequency guard (0.1 Hz) clamps spurious no-load pulses to zero, matching behaviour observed in the Arduino reference implementation. Absolute accuracy is ±15% without calibration due to the chip's internal oscillator tolerance. Co-authored-by: Claude <noreply@anthropic.com>
Replace the stub voltage/current fields in SensorData with real
measurements from the HLW8012 driver:
- SensorData: remove current_a:[f32;8] stub; add voltage_v, current_total_a,
power_w (all driven by the HLW8012).
- sensor_task: add Hlw8012Driver<'static> parameter; measure power,
current, and voltage each cycle (voltage read toggles SEL and waits
2 s for stabilisation).
- main.rs: bind PIO0_IRQ_0, initialise Hlw8012Driver on GPIO 8/9/10,
pass it to sensor_task.
- GET /api/sensors: replace current_a array with current_total_a and
power_w fields.
- index.html: add Current and Power tiles to the sensor bar; remove
per-relay current stubs (HLW8012 measures total input only).

Five errors were reported by cargo deny: 1. 0BSD not in license allow-list: managed + smoltcp (both transitive deps of embassy-net) use this OSI-approved permissive license. Added "0BSD" to [licenses].allow. 2. CDLA-Permissive-2.0 not in allow-list: webpki-roots is pulled in only by ureq inside the host-only xtask crate. Added xtask to [graph].exclude so its host-only transitive deps are not audited against the embedded firmware license policy. 3. xtask unlicensed: added license = "Apache-2.0" to xtask/Cargo.toml. 4. RUSTSEC-2024-0436 (paste unmaintained): paste is a transitive build-time dep via pio-core -> pio -> embassy-rp. No safe upgrade path exists until pio-core migrates upstream. Added an [[advisories.ignore]] entry with a documented rationale. 5. keccak 0.1.5 yanked: bumped to 0.1.6 via cargo update -p keccak. This is a build-time dep (lalrpop -> sha3 -> keccak).
