//mod edit: Wątek zawierający bardzo cenne dane techniczne. **Integracja:** Sprawdzone kody dla Node-RED (Modbus RTU). **Sprzęt:** Wymagany konwerter RS232-USB (zalecany FT232 z separacją galwaniczną). Jak ktoś potrzebuje to pokonałem komunikację z falownikiem offgrid POWLAN. Obecnie po aktualizacji powstał problem z NODE RED i modułem modbus. Próbuje z aktualizacją ale komunikat brak internetu zatrzymuje proces. ---

Witam wszystkich Jestem tu nowy i dość zielony w temacie Potrzebuje pokonać komunikacje z falownikiem offgrid SML-III-3.5KW-WIFI (chinski dość popularny model). Dostałem w zestawie styk rj45 dwa kable rs232 i rs485, datalogger wifi na rs232. Mam takie 3 falowniki wiec sprawa jest trzykrotnie skomplikowana. Dodatkowo to jestem całkiem nowy w tym temacie. Szukałem jakiegoś konwertera z rs232 na zwykły lan rj45 i żeby po skrętce skomunikować to z HA. Moze da rade jakoś bezpośrednio z datalogger wifi. Utknąłem. Nie potrzebuje dostępu do ustawień falownika tylko do informacji o aktualnej produkcji stanie baterii itd., czyli wszystko co można użyć w energia. i później do sterowania obciążenia (inne urządzenia, nie inverter) Na ten moment nie mam pomysłu, gdzie szukać. Ma ktoś może jakiś pomysł jak to ogarnąć? ---

Jeśli jakieś urządzenie ma modbus i masz do niego prawidłowy wykaz rejestrów to musi działać … nawet bez żadnej wyszukanej integracji. Trzeba to robić sukcesywnie aby znaleźć źródło problemu. Na początek połacz się z kompa za pomocą jakiegoś programu pt. “Modbus master”. ---
