Is it possible to build a modbus rtu gateway/multiplexer?

[tobox]

In several installations, there are several modbus masters that want to read the main power meter, e.g. electric car charger, heat pump, solar inverter, battery inverter... My electrician says I need separate modbus meters for each modbus master.

Would it be possible with this library to build a device with several modbus client ports, that would forward the requests over a single modbus server port to a physical modbus meter (and then send the responses back to the originating port)?

Sure. The library instances on single device is limited just by hardware. There is examples on how to build bridges.
