Isolar SMR II 5.5KW communication rs232

[wincenty271]

Hello.
I’ve been trying to connect to my inverter for some time now (Isolar SMR II 5.5KW).
After many tries and reading guides, I was able to connect.
When uploading the test code for communication (esp8266-test-protocols.yaml) the inverter responds to everything.

please help what do I need to do for communication and reading to work properly.

Hi, have you solved it? Instead, I would like to find a guide to read the data of an smr II ALIL MIO HOMEASSIST FOR NOW I HAVE AN SMG II INVERTER AND IT WORKS VIA USB.
THE INVERTER I WOULD LIKE TO BUY WOULD BE AN SMR II 6KW 48V, COULD YOU SHARE THE TUTORIALS WITH ME, THANKS.
Ciao hai risolto ? Io invece vorrei trovare una guida per fare leggere i dati di un smr II ALIL MIO HOMEASSIST PER ORA HO UN INVERTER SMG II E FUNZIONA VIA USB .
LINVERTER CHE VORREI COMPRARE SAREBBE UN SMR II 6KW 48V , MI POTRESTI CONDIVIDERE I TUTORIAL GRAZIE.
