Question: QCells Integration not working- Error Message

[masterdot]

I have a QCells Inverter at home and did get it integrated with a Waveshare to TCP Adapter (Waveshare RS485 to RJ45 Ethernet Converter Module, Industrial Rail-Mount RS485 Serial Server,TCP/IP to Serial Module,300~115200 BPS Baudrate,10 / 100M Auto-Negotiation RJ45 Connector). Its integrated in Homeassistent with the HACS SolarX Component (SolaX Inverter Modbus) and it works just fine.

But I dont get it running in evcc, I did try every combination of all QCells and SolarX options. But I do get everytime a error message Teste die grid Konfiguration von Solax Hybrid X1/X3 G3/G4 ... Fehler: read failed: modbus: response transaction id '7' does not match request '6'
Any idea? Googling didnt help.

Looks like a wrong configuration of your converter or evcc.yaml.

Any Idea what may help?
Wähle ein PV System: Qcells Q.HOME ESS HYB-G3 Führe folgende Einstellungen durch: Wähle die ModBus Schnittstelle aus Serial (Ethernet-RS485 Adapter) Modbus ID 1 IP-Adresse oder Hostname 192.168.178.48 Port 4196 Teste die grid Konfiguration von Qcells Q.HOME ESS HYB-G3 ... Fehler: read failed: modbus: response transaction id '8' does not match request '7'

Normally that should be the right setup, right? The port is 4196, not 502 as ususal.

Work Mode: TCP Server
Device Port: 502

Check the serial port parameters again if it matches the settings of your device.

As you enabled the Modbus RTU to Modbus TCP protocol conversion you also need to adjust the evcc configuration to talk Modbus TCP to your converter.

Im currently "stuck" in the config creator. Is there any way to setup my stuff with the correct parameters? Or should I run the config and then edit the config manually afterwards?

This are the error messages now in evcc:

The waveshare is now configured like this here:

Thanks for your help! I really appreciate it!

Ok, I had some nerve to try and error my config.
Now its working.

meters:
- type: template
  template: solax 
  # RS485 via TCP/IP (Modbus RTU)
  modbus: tcpip
  id: 1
  host: 192.168.178.48 # Hostname
  port: 502 # Port
#  rtu: true  
  usage: grid 
  name: grid1

Maybe this would help others. My stuff is a qcells installation with:
Q.VOLT HYB-G3 8.0kW 3P
Q.SAVE MATEBOX-G3 3P
and the fitting Battery System.

This is my modbus/ tcp converter:

This are my settings:

Maybe this must be corrected/ added to the config.
If there are any questions, I'll help :)
