@pawell32 skopiuj tą scieżkę, wklej do notatnika i zobacz jak wygląda, potem musisz użyć funkcji żeby odpytać zmienną "radio" i zapsać do nowej zmiennej ten konkretny atrybut i dalej wysłać go jako payload. Pokazałem przykład już wcześniej tylko nie wiedziałem co chcesz zrobić z tym atrybutem title

@isom 

new_state.attributes.media_title

jak uzyć funkcję, nie kojarzę tu

@pawell32 nod funkcja, na poniższym foto zmienna przepust przechowuje pozycję przepustnicy kominka, kiedy zostanie wysłane polecenie ustaw na 40% nie chcę żeby przy kolejnym cyklu znów było wysłane do przepustnicy to polecenie, chyba że poziom jest inny niż 40%

 Jak widać GET odpytuje zmienną , potem zapis do var - poziom samego atrybutu position i prosty IF

Ty masz jeszcze łatwiej 

podmień swojego noda event

@mariusz-2 dziękuję i  poczytam jeszcze nt. To co mi podpowiedzieliście to działa, wymaga dopracowania, ale to po świętach. Na niektóeych wyświeltla mi np. tylko wykonawcę, tytuł jest po przecinku i tego już nie. Spoko i wesołych.
