Why the value of variables is not coherent (see the screenshot). The value on the variable finder is the correct value. But If I add a timeline advise and insert the variable, it show an previous value of the variable.
Not sure how to interpret your question. The tag you are hovering over with your mouse, on the right hand side of your screenshot, is the date tag, which shows today’s date: 20-4-2026. Why is that not correct?
The variable ‘Luz_dia_consultado’ at the left pane shows real value: 2026-04-26 but in the left pane, over the message I try to send to the timeline shows: 2026-04-20. That is the previous value of the variable, not the last.
When it shows previous values when using that notification card, most probably the calculations aren’t completed yet.
In case you send it per notification card right after the actual calculation (guessumption, as can’t see that on your screenshot…) add one or a few seconds delay to it. This allows calculations to complete first, before you send them elsewhere.
Just to double check: the date tag you were hovering over in your screenshot, is that the built-in date tag provided by Homey (that was my understanding). If so: you cannot change the value of that tag; it is determined by Homey and shows today’s date. But maybe you were hovering over a different tag.
If you were referring to the calculated variable then I misunderstood you and than indeed, as @Peter_Kawa indicated, there might be a slight delay in the updates.
No, the screenshot is not of the system variable “date”. It’s of a variable I created, updated by a script that runs once a day. As the screenshot shows, the variables window indicates that the variable has the correct value; however, the variable ‘within’ the card displays an outdated value.
