How is it working for Pi5?

bablokb commented 1 week ago

You don't need this project for a Pi5. The Pi5 has an internal RTC that will happily wake up the Pi5.

You can set the wakeup time with (execute as root):

date -d "+10 minutes" +'%s' > /sys/class/rtc/rtc0/wakealarm

The date command is very powerful, see the man-pages. You can pass relative times as in my example above, or absolute dates. Some more examples:

date -d tomorrow  +'%s' > /sys/class/rtc/rtc0/wakealarm
date -d "tomorrow 08:00" +'%s' > /sys/class/rtc/rtc0/wakealarm
date -d "next monday 08:00" +'%s' > /sys/class/rtc/rtc0/wakealarm
date -d "+5 minutes" +'%s' > /sys/class/rtc/rtc0/wakealarm
date -d "+5 hours" +'%s' > /sys/class/rtc/rtc0/wakealarm
date -d "22:30 2024-10-21" +'%s' > /sys/class/rtc/rtc0/wakealarm

Thanks just tested it, and it worked. But its still consuming 1.9 Watts in Sleep Mode. Any Idea?

Yes, you have to update your EEPROM-settings. You should add:

POWER_OFF_ON_HALT=1

Edit with:

sudo rpi-eeprom-config --edit

and reboot afterwards.
