Hello Juha Lempiainen,

First,
Thanks for coming here and asking a question.
Would you be so kind as to adjusting the format of your code so that we can read it properly & check the YAML spacing, etc. Editing your original is the preferred way. It is very hard for us to tell what is what when the text formatter jumbles everything like that.
You can use the </> button or this or…

Here is an example of how to fix it from the site FAQ Page.

Second, would the workday sensor help in any way?
