This python script calculates the sunrise and sunset times for given coordinates and updates the configuration of an Omlet Smart Automatic Chicken Coop Door.
The script is intended to be executed at least once daily to update the opening and closing times for the next open and close events, depending on the current time.
It can be used with Docker and scheduled to run regularly using a cron job, either by starting the container or by running the script directly.

Environment-Variables needed:

TIMEZONE="..."
COOP_LATITUDE=
COOP_LONGITUDE=
OMLET_API_TOKEN="..."
OMLET_DEVICE_ID="..."

import os
from datetime import date, datetime, timedelta
from dateutil import tz
from suntime import Sun
from smartcoop.client import SmartCoopClient

LATITUDE = float(os.environ.get('COOP_LATITUDE'))
LONGITUDE = float(os.environ.get('COOP_LONGITUDE'))
TIMEZONE = tz.gettz(os.environ.get('TIMEZONE'))
OMLET_TOKEN = os.environ.get('OMLET_API_TOKEN')
DEVICE_ID = os.environ.get('OMLET_DEVICE_ID')

sun = Sun(LATITUDE, LONGITUDE)
today = datetime.today()
tomorrow = today + timedelta(days=1)
now = datetime.now(TIMEZONE)

sunrise_today_utc = sun.get_sunrise_time(today)
sunset_today_utc = sun.get_sunset_time(today)
sunrise_tomorrow_utc = sun.get_sunrise_time(tomorrow)
sunset_tomorrow_utc = sun.get_sunset_time(tomorrow)

sunset_today = sunset_today_utc.astimezone(TIMEZONE)
sunrise_tomorrow = sunrise_tomorrow_utc.astimezone(TIMEZONE)
sunset_tomorrow = sunset_tomorrow_utc.astimezone(TIMEZONE)

print('Sunrise today:', sunrise_today)
print('Sunset today:', sunset_today)
print('Sunrise tomorrow:', sunrise_tomorrow)
print('Sunset tomorrow:', sunset_tomorrow)

if now > sunrise_today:
    open_time = sunrise_tomorrow
else:
    open_time = sunrise_today

if now > sunset_today:
    close_time = sunset_tomorrow

Added some limits (Environment-Variables😞

EARLIEST_OPEN_TIME="08:00"
LATEST_OPEN_TIME="10:00"
EARLIEST_CLOSE_TIME="18:00"
LATEST_CLOSE_TIME="20:00"

(edit: The function name p*****_optional_time is actually p a r s e_optional_time (without whitespaces) in the original, but it seems to be censored because "p a r s e" contains the word "a r s e".)
