155 Holiday Automatic Power On/Off Solution

The server periodically determines holidays, uses WOL to power on and SSH to shut down, so the 155 computer runs on demand.

This project addresses the automation requirement for the .155 Windows computer to stay powered on during holidays/weekends and to be fully shut down after the holiday ends. Because the computer cannot sleep (the GPU light stays on), and a cold start of WeChat requires scanning a QR code with a phone, the decision logic is placed on the .223 server: the script windows155_period.py checks at 18:00 every day whether "tomorrow is a holiday and today is a workday"; if so, it sends a WOL magic packet to power on the computer. At 08:00 every day, it checks whether "yesterday was a holiday and today is a workday"; if so, it shuts down the computer remotely via SSH, and automatically skips if the computer is already powered on or already shut down. Holiday data comes from GitHub's holiday-cn, includes weekends and make-up workdays, and supports caching and daily updates; before 2027 data is released, it falls back to weekend determination. On the Windows side, automatic login, WeChat auto-start, and a Moments sync scheduled task are configured, so the computer stays online after booting, and shutdown is triggered uniformly by the server. The solution has completed dry-run and actual testing: weekend and National Day date determinations are correct, the computer boots about 25 seconds after WOL, and SSH becomes available in about 26 seconds.

Features

  • 按“节假日前一晚 18:00”自动 WOL 开机，假期期间保持开机
  • 按“节后首个工作日 08:00”SSH 远程关机，避免休眠
  • 基于 holiday-cn 自动判断周末/调休，缓存并每日更新
  • 已开机/已关机状态自动跳过，支持 --force 手动补发
  • Windows 端自动登录、微信自启与朋友圈同步计划任务
  • systemd timer 定时执行，旧周五唤醒定时器已禁用

  1. Prepare the environment: keep /opt/projects-site/scripts/windows155_period.py on the .223 server, and confirm that the WOL and SSH remote shutdown chain for the .155 Windows machine works.
  2. Configure timers: create and enable win155-period-wake.timer (daily at 18:00) and win155-period-shutdown.timer (daily at 08:00); after making changes, run systemd daemon-reload. The old blog-wake155.timer has been disabled.
  3. Configure Windows: enable automatic login and set WeChat to start automatically; create a logon-triggered scheduled task MomentsNightlySync, whose flow is to start WeChat, wait for QR code scanning (up to 6 hours), run nightly_sync.ps1 to sync Moments and keep the machine powered on; create MomentsDailySync for incremental sync every day at 02:00.
  4. Manual verification: on .223, run python3 /opt/projects-site/scripts/windows155_period.py --mode wake --force to test startup, and run --mode shutdown --force to test shutdown. Measured results show that after WOL the machine boots in about 25 seconds, and SSH becomes available in about 26 seconds.
  5. Daily use: no intervention is required; holiday data is pulled automatically, and after the 2027 schedule is published, the script will update automatically. To change the rules, modify the script or timer, then run daemon-reload.
