Oczywiście mam w domu zainstalowane panele fotowoltaiczne nad którymi panuje falownik firmy Sofar. Jest możliwość jego monitoringu poprzez oryginalny logger falownika i chmurę. Ja jednak preferuje uniezależnić się od dostępu do Internetu i skrócić komunikację z kilku tysięcy kilometrów (serwer gdzieś w Chinach) do kilu centymetrów bezpośredniego przewodu.
Tutaj też nie trzeba było za bardzo kombinować wystarczyło poszukać. Tu wyręczył mnie mój rodak i udostępnił wszystko na GitHub-ie1. Trzeba tylko buło połączyć dwa moduły i hula. Tym razem jest jeszcze prościej niż analogiczne podłączenie do Rekuperatora. Komunikacja jest po zwykłym RS232 protokołem MODBUS. Dlatego można było skorzystać z dodatku do HA jakim jest ESPHome.

A tutaj widać co uzyskujemy w HA.
Przy okazji wspomnę że HA ma specjalne usługi do przedstawiania dystrybucji energii w domu. Tutaj mamy grafikę przedstawiającą w jaki sposób ją przedstawia. Mamy tu ujęte m.i. informację uzyskane z falownika jeśli chodzi o produkcję energii. Energię Gazu uzyskany z pieca Vaillant. W następnych wpisach na moim blogu opiszę w jaki sposób mam dane do pozostałych elementów Sieć i Woda.
