working mode on reduced speed esp32 on esphome

d32_1.yaml

###  config template for deep sleeping esp32 devices
###  This is modelled on lolin32 D32 ( not pro )

#  uses gpio pin visible to rtc to wake up on motion
#  uses mt3608 step-up dc-dc converter to power rcwl-0916 microwave sensor
#    > 11 volts is way more sensitive than 3 or 5 volts for microwave
# using hourly wakeup just to keep up with battery life.
#  using 80Mhz clock / high wifi powersave to lower consumption
