ESPHOME c++ module for RS485 communication

I will commission the writing of a module (can be Modbus) for ESPhome software for modbus device connectivity.

The idea is to create Custom Components that will enable the networking of ESP32 devices.

One works as a Modbus master the rest as slaves, on the slave we click on a binary sensor and it transmits its state to the master.

Similarly for temperature and humidity sensors.

Also from the master we call the switch action and on the slave it changes the state of the switch.
