Create binaire variable

App version: 2.26.0
Phone OS: Android

I have a little question. I tested Olisto a few months ago. I resume my tests to see the evolution, however previously I had created variables with a name: “variable_example”
Then I came to give it a value of 0 or 1.

I could then recover the value as a condition in my triggs. For example: I am on vacation 0 -> No / 1 -> Yes.
Then I made a daily scenario, and in my conditions I added a variable:

  • If the sun is up
  • If variable_example = 0
    Then …

How can I do the same today?
Thank you very much for your reply.
