As a work around, I installed "Modbus TCP to Modbus RTU Gateway Add-on" and used the pymobus serial connection 

DEVICE: /dev/ttyUSB0
BAUDRATE: 9600
MODE: 8N1
TIMEOUT: 5
LOGLEVEL: 2
 

PORT: xx.xxx.xxx.xxx:502
DEVICE: /dev/serial/by-id/usb-1a86_USB2.0-Ser_-if00-port0
DRIVER: pymodbus

I've updated the fault finding section to include this. kellerza/sunsynk: Sunsynk Inverter Python library and Home Assistant OS Addon (github.com)

In your case, `DEVICE` is ignored, it uses `PORT` if it contains any value.

In all cases I would still use the umodbus driver, since it is much more reliable to reconnect. You can see from Jack's log pymodbus disconnected for some reason (last error in his log). 

I only use the pymodbus driver to do basic development work from windows, else I use umodbus. Will update the docs
