Jak wykreślić w HA wykres funkcji obliczającej się w Node-RED?

Krzysztonek · 17 Sierpień 2023 20:40

Przede mną nie lada wyzwanie - na karcie w HA chcę wykreślić wartości funkcji Node-RED obliczającej biorytm.

W Node-RED jeden z nodów typu function wylicza mi wartości tej funkcji z parametrów typu data i zwraca 30-elementową tablicę jej wartości tab [0,…,29].:

tab[i] = Math.sin ( 2 * pi * (Math.round((new Date(dzien).getTime() - new Date(urodziny).getTime()) / doba) - 1) / 23)
# i - licznik pętli; dzien - kolejna data z zadanego przedziału czasu

Muszę teraz tę funkcję jakoś wykreślić na którejś z kart w HA (np. custom:mini-graph-card). Nie mam pojęcia w jaki sposób wartości tej funkcji wystawić na kartę nie mając żadnej dedykowanej encji, jedynie tablicę wynikową z funkcji w NodeRED…

Parametr wejściowy do funkcji jest jeden: data urodzin. Funkcja oblicza swoją wartość dla każdej daty w przedziale od (dziś-15dni) do (dziś+15dni), dlatego tablica wynikowa ma 30 elementów. Nawiasem mówiąc mam aż trzy takie tablice, osobne dla każdego z 3-ech cykli (P, E, I).
Pierwotnie cały algorytm obliczeniowy chciałem umieścić w templatce definiującej dedykowany sensor, ale niestety Jinja2 jest bardzo uboga w zaawansowane funkcje matematyczne (np. brak funkcji trygonometrycznych czy funkcji przeliczania dat), więc ten pomysł się nie sprawdził.
Stąd próba (całkiem udana) zapisu algorytmu w nodzie funkcyjnym NodeRED. Ale trzeba to teraz jakoś wydobyć z tablicy wynikowej i wywalić na ekran w postaci wykresu…
Pytanie do ekspertów w tej dziedzinie: Czy macie jakiś pomysł jak to zrobić?

może tak spróbuj po MQTT powinieneś otrzymać wartość z 1 tablicy, ale jak utkać całą tablicę w jeden sensor nie mam pojęcia, choć próbowałem się trochę pobawić, ani tablica ani string nie wchodzi.

Mógłbyś podesłać także flow.json? Chciałbym się temu przyjrzeć, bo nie bardzo qumam jak to działa.
No i jak to się dzieje, że na Twoim ekranie obok schematu pojawia się okienko do grafiki? Nigdy z tego nie korzystałem, nawet nie byłem świadom takich możliwości NR…

To jest tylko przykład nie i wiem czy zadziała to w twojej konfiguracji.
