Hi Sebastian,
I'm new to home assistant and Esphome.
Easun Hybrid Inverter SV IV 11.2KW = 2PCSSV IV 5.6KW +2PCSParellel Kit. I try to receive data from them (for now only from one)
I have a D1 mini with RS232-to-TTL ... in my opinion correctly connected to one inverter.
This is a log. file.

I don't get data in HA

I also tried the protocol test configuration.
This is also his log. file.

Where am I wrong?

It looks like you have attached the inverter to GPIO1/GPIO3. The logger writes to the same GPIOs per default. Please set the baud_rate: 0 of the logger to 0 and try the protocol test again.

Yes, Inverter is connected to GPIO1/GPIO3
If I have to move it to GPIO4/GPIO5

Please use GPIO4/GPIO5 or disable the serial output of the logger:

logger
  baud_rate: 0

You cannot have both on the same GPIOs.

Your inverter responds to all requests (different protocols) with NAK (no acknowledgement). That's strange.

I talked to the seller, he gave me this protocol, but the title shows that he is for the old model. who has protocol Pi18

That I think is the correct answer

Good catch! Yes, this looks like a valid response. But this protocol isn't supported by the pipsolar component yet.

Hello again ,
I put the new supplement for Pi18, but I think it doesn't work correctly. This is my protocol. Here you talk about the same protocol as mine.
#48
My knowledge is not enough to do it myself
I see that here they are doing something like that
