1. Rule driven - copy the required JSON content to any rule buffer preceded with ``rule3 on file#modbus do `` and
followed with `` endon``.
2. File system driven - if a file system is present (every ESP32) create a file called ``modbus.json`` and copy the required JSON
2. Script driven - copy the required JSON content to a script preceded with ``>y`` and
