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.

(log from the not connected inverter to the panels and battery)

But when uploading the code to read the value (esp8266-example.yaml) and similar codes for HA it does not work :(
I get an error: "timeout command to poll: ... "

(log from the connected inverter to the panels and battery)
