Cześć, nie mogę się połączyć z R4DCB08 przez modbus który jest wbudowany na płycie KC868-E16S, Przez adapter usb i qmod master odczyt temperatur jest poprawny natomiast przez ESP nie mogę dostać się do konkretnych rejestrów.
Link do dokumentacji:

Pokaż co odczytałeś w qmod master a potem jak próbujesz to samo odczytać w ESPHome.

Kod jest dla dwóch modułów R4DCB08.
Ok udało się rozwiązać problem.
Jednak przewody modbus muszą być podłączone zgodnie z dokumentacją. Jak podłączyłem odwrotnie i mimo zmiany w kodzie nie przyniosło to efektu. Musiałem zmienić fizyczne podłączenie.
Kod jest poprawy i działa więc zostawię jak by ktoś potrzebował.
