Comparing 2 dates

Hello all,

for the logic of a script managing my irrigation system I would like to do the following:

1. Each time the irrigation takes plays save the date in a variable
2. take the timestamp as a date of today.
3. tell me the amount of days between today and the lasst irrigation

To be honest: I was not able to write this simple script!

Best regards

As an alternative to storing all these variables and writing a script, you could consider using the Timers and Pesters https://wiki.indigodomo.com/doku.php?id=indigo_7_documentation:plugins:timersandpesters plugin to:

1. Start a timer when the first irrigation occurs
2. Reset the timer on each irrigation
3. Show your timer value on a control page, or Alexa, or however you want to find out the info

Thx, but I need a solution as described.

But thank you for help!

Code: Select all

import datetime as dt

#  date_1 = indigo.variables[12345].value()  # This is how you get the value of an Indigo variable
date_1 = "2021-08-09 12:34:30.12345"  # Indigo variables are strings, so they must be converted
date_2 = "2021-08-12 23:45:00.54321"

d1 = dt.datetime.strptime(date_1, "%Y-%m-%d %H:%M:%S.%f")  # This is how you convert the strings to date objects
d2 = dt.datetime.strptime(date_2, "%Y-%m-%d %H:%M:%S.%f")

diff = d2 - d1

indigo.server.log(str(diff.days))

If you want fractional days, the last line would require a bit more effort (but not a lot more effort).
