Hi,
i working with a UPS HAT v2 and i wanna know if when the DC power input is disconneted and the the power is just of the battery i can keep the system running and when the battery is low he just turn off safely.
I searching for the use of set_safe_shutdown_battery_level but i can’t use this i don’t know why, can be because of the firmware version? what is the newest?

the set_safe_shutdown_battery_level was removed? @ensar

Hi @falconeee ,

Yes, it was removed. All available functions are here: sixfab-power-python-api.power_api.power_api API documentation

Thanks for the answer! For the safe shutdown now i can use the power outage? When run_time come to the end the system shut down safely?

Yes, you can use it. Note that you need to enable the power outage event state.

Do you have an example for how to guarantee that the rPi is shut down when the battery reaches 3.1V or level==5% (I don’t care which of these two)? @ensar

from power_api import SixfabPower
import time

api = SixfabPower()

api.set_power_outage_event_status(2) #set power outage event

while True:
if api.get_battery_level() < 10: #if battery level below 10% shutdown
api.set_power_outage_event_status(1)
print(‘shutdown’)
else:
print(‘keep working’+ ’ ’ + str(api.get_battery_level()))

time.sleep(5)

Thanks! But if the rPi hangs for whatever reason then this ceases to work and the HAT won’t shut down at all.
