Interactive walkthrough of the move from hibernate/rtcwake scheduling to the per-minute trigger timer: why the old model broke when the PC stopped being shut down, the login-fire hole that came with it, the fire window and its catch-up, and the four-step alarm resolution chain. Includes a simulator that runs the real _decide() rule, so the window and the gate short-circuit can be poked at rather than just read about.

wake_alarm
A phone-driven wake alarm for an always-on PC. The alarm time is whatever the
companion phone app last synced (via the shared crdt_sync transport over a
private GitHub repo); a per-minute systemd user timer fires at exactly that
time, showing a fullscreen, challenge-dismissed alarm with fan ramp and
optional TP-Link Tapo P110 smart-plug control.
Change the alarm on the phone at any hour and the PC follows within ~5
minutes. If the PC does happen to be powered down, a shutdown wrapper
hibernates with rtcwake set to the same synced time, as a fallback.
Install
bash install.sh
This installs the package + dependencies into system Python's user
site-packages (the systemd units run /usr/bin/python directly, not a venv —
see CLAUDE.md), installs and enables the per-minute trigger timer, the
systemd-sleep resume hook, the shutdown wrapper that hibernates with
rtcwake as a fallback, the fan-ramp script, and (optionally) python-kasa
for smart-plug control.
Reading the phone's alarm needs a GitHub token with repo scope, at
~/.config/wake_alarm/sync.json as {"token": "..."}. If that file is
absent, a sibling app's ~/.config/{diet_guard,screen_locker}/sync_token is
used instead, so one token covers every app syncing through kuhyx/syncs.
Usage
python -m wake_alarm._alarm --demo # test the alarm window (safe, closeable)
python -m wake_alarm._sync --show # what alarm time the PC resolves
python -m wake_alarm._trigger --dry-run # what the next tick would do
journalctl --user -fu wake-alarm-trigger.service # watch it live
The alarm fires automatically once installed; no manual invocation is needed in normal operation.
Development
python -m venv .venv && .venv/bin/pip install -r requirements.txt
.venv/bin/pre-commit install && .venv/bin/pre-commit install --hook-type pre-push
.venv/bin/python -m pytest wake_alarm/tests/ --cov=wake_alarm --cov-branch --cov-fail-under=100
