Examples

Library Usage

from datetime import time, datetime
from macpower import MacPower, PMSetting, PMScope, PMEventType, PMRepeatEvent, PMWeekday

pm = MacPower() # or: pm = MacPower(sudo=True)

source = pm.power_source
print(source) # e.g. PMPowerSource.ACPower

status = pm.battery_status()
print(status.source)          # Power Source Type
print(status.percent)         # Battery level (% as a int, e.g. 93)
print(status.state)           # charging / discharging / charged
print(status.time_remaining)  # timedelta or None
print(status.present)         # True / False / None

# Setting Management
pm.set_setting(PMSetting.DisplaySleep, 10) # Set the Display Sleep to 10 seconds for all Power Sources
pm.set_settings( # Change Multiple Settings in one call
    {
        PMSetting.DisplaySleep: 10, # Display Sleep to 10 seconds
        PMSetting.Sleep: 60, # System Sleep(Suspend) to 60 seconds
        PMSetting.PowerNap: 1 # Enable the PowerNap feature
    },
    scope=PMScope.All # Apply to all Power Sources
)
pm.set_setting("tcpkeepalive", 1, scope=PMScope.Battery) # You can also use string for Setting ID

# Create a One-time Schedule
when = datetime.now().replace(hour=9, minute=0, second=0) + timedelta(days=1)
pm.schedule(PMEventType.PowerOn, when)

# Create a Multiple-time Schedule (Repeat Event)
event = PMRepeatEvent(
    PMEventType.Shutdown,
    PMWeekday.M | PMWeekday.T | PMWeekday.W | PMWeekday.R | PMWeekday.F, # Monday ~ Friday
    time(23, 0) # 23:00
)
pm.repeat(event)

# Wake up after 10 seconds
pm.relative("wake", 10)

# Sleep now
pm.sleepnow()
