Is your feature request related to a problem? Please describe.

There is a Modbus TCP-ready energy meter in the meter cabinet that I would like to integrate in order to control the output of the inverter.

Describe the solution you'd like

An option for open configuration of the Modbus TCP slave with IP address, Modbus ID and register to be polled.

Describe alternatives you've considered

while this is a great request, i guess it takes some time (and a motivated developer) to get integratet

in the meantime, you can use a tasmota device to read out your meter. tasmota SML supports modbus TCP and can publish your meter data via mqtt.
