Problem to conect whith ISolar_SMG_II_4KW_24V WiFi

[Sensorv]

Hello.
I have a problem.
I can't connect and configure my inverter ISolar_SMG_II_4KW_24V WiFi to Home Assistant.
I use the file esp32-example.yaml to configure

All sensors and switches are inactive and off.
I use esp32 wroom 32.

Help me figure out the settings and connection
I attach еhe log and yaml file.

Thanks

Let's ignore Home Assistant for now and let's focus on the ESPHome log. Please enable the debug output of the uart component:

I guess there is just outgoing (>>>) traffic but no incoming (<<<). If this is the case we have to check your wiring as next step.

Thank you. I solved the problem. There was no contact on the signal line from the inverter. Now everything works.
