Deep sleep for a specific time

I need to activate a peripheral for a specific time, then sleep for some time, and then deactivate the peripheral again.

I could do this with a simple sleep but that would keep my ESP32 awake and burn battery. Is there a way to go into deep sleep for the required time and then wake up again?

Ideally I would simple schedule to run a deactivate program after a certain duration.

What's the best way to do this?

Toit has the following example for putting an ESP32 into a deep sleep for 10 seconds.

import esp32

main:
  run_time ::= Duration --us=esp32.total_run_time
  sleep_time ::= Duration --us=esp32.total_deep_sleep_time
  print "Awake for $(run_time - sleep_time) so far"
  print "Slept for $sleep_time so far"
  esp32.deep_sleep (Duration --s=10)
