Modbus JSON configurations

Modbus JSON configuration data for use with generic Energy Modbus driver.

Options to select modbus JSON data

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

Notes

• To enter long rules using the serial console and solve error "Serial buffer overrun" you might need to enlarge the serial input buffer with command serialbuffer 800
• Changes to configurations are activated only after command restart
