Working on integration for Hisense AEH-W4A1 module

Hi everybody! I have a couple of questions about the python integration here.
I have XMV.4.4.7. I’m having the same errors like this. Any idea how to solve it?
Do you know how to change the password of the aeh-w4a1 device?

Cheers

I use a normal rs232 rs485 converter attached to esp8266 serial port, you can deduce pinout and wiring from photo, for serial command i use documentation from github.
