- Per-pin bar now scales against the 9.2 A per-pin rating (10 A full
scale, red at/over rating) instead of the 55 A total connector OCP
- Debounced app-wide warning banner (visible on all tabs) when the
current between two pins diverges by > 2 A for ~7 s - the signature
of a bad pin contact that can overheat and melt the 12VHPWR
connector; 5 s grace period after clearing
- New pin_imbalance_a sample field (max - min pin current) in both the
serial and hwmon sample builders, plus frontend type
- Docs: README + WireView.md cover the warning and threshold; fresh
screenshot with the new per-pin labels
- Tests: vitest setup + 9 unit tests for the debounce state machine;
3 new backend checks for pin_imbalance_a
A stale venv after a code update (editable install + git pull) left
pyserial out of the environment, and the hard module-level import in
wireview.py took the entire web server down — even on machines without
a WireView device.
Guard the import: without pyserial the serial transport is disabled
(one-time warning, connect fails, reads return None) while the rest of
the server keeps running. The hwmon transport is unaffected.
Also simplify the except clauses to OSError (SerialException is an
OSError subclass) so they no longer reference the possibly-None module.
Standalone support for the ThermalGrizzly WireView Pro II without
depending on the external wireview_reporter exporter:
- wireview.py: serial protocol (STX/ETX + 16-bit CRC16-CCITT) with
vendor-data product identification, config version, UID, build
string, screen layout, and temperature/power/current sensor reads;
hwmon fallback with per-channel index resolution; udev-based
detection (vendor 0x2560 / product 0x0101) with fallback port
probing; serial read timeout and watchdog reconnect
- server.py: startup detection (root only), 1 Hz poller gated on
subscribed clients, WS 'wireview' channel, GET /api/wireview,
rejected-product memoization, stale-read race guard
- frontend: WireView tab (visible when a device is detected) with
live temperature/power/current cards, sparkline history, and
device info; nullable temp channels
- tests: 76 tests covering parser, CRC, fault classification,
hwmon resolution, JSON safety, and the serial transport against
a pty-based fake device
Verified live: tab appears with the device connected, disappears
when unplugged, reconnects on re-plug, no serial traffic when idle.
