Unable to connect via Modbus TCP

[markhaines]

Am unable to connect to my FoxESS inverter using Wavshare Modbus adapter over TCP. I can access the same fine using the FoxESS Modbus integration (I have multi connections enabled on the device itself. IP & Port are correct, I can't see anywhere on the device that details a Slave ID though (am using the default). I can connect fine via the cloud connection but would prefer to have it configured locally. --> HACS installed Version 1.9.1, have also tried rolling back to earlier 1.8 version.

-->

Describe the bug

Unable to complete installation as integration will not communicate with Modbus device over TCP.
