CLI

python -m wakepy [-h] [-s]

optional arguments:    
  -h, --help               show this help message and exit
  -s, --keep-screen-awake  Keep also the screen awake. On Linux, this flag is set on and cannot be disabled.

Set keepawake within a python script

from wakepy import set_keepawake, unset_keepawake

set_keepawake(keep_screen_awake=False)
# do stuff that takes long time
unset_keepawake()

Parameters

• keep_screen_awake can be used to keep also the screen awake. The default is False. On Linux, this is set to True and cannot be changed.

Details

Windows

The program simply calls the SetThreadExecutionState with the ES_SYSTEM_REQUIRED flag, when setting the keepawake, and removes flag when unsetting. The flag cannot prevent sleeping if

• User presses power button
• User selects Sleep from the Start menu.

Linux

The program uses the systemctl mask command to prevent all forms of sleep or hybernation when setting the keepawake, and unmasks the functions when unsetting keepawake. This command will remain active until keepawake is removed. The flag cannot prevent sleeping from user interaction. This action does require sudo privileges.

Darwin (macOS)

The program calls the caffeinate command when setting keepawake, and sends a break key-command when unsetting. The flag does not prevent the user from manually sleeping the system or terminating the caffeinate process.
