Add ModbusRTU

[pruwait]

Very good project!

Ideas to do:
Save/restore current color palette & effect in EEPROM
Now it works with web power button only. Need restore memory on start ESP8266.

Add ModbusRTU cotrol (WLED is modbus slave)

Hi!
Awesome, great that you like it!
Saving the current effect config is supported via presets (the 1-16 numbers in favorites tab)!
You can also set one of them to be applied on start with the "Boot preset" option in LED settings :)

Ok, I will think about Modbus. What controller are you interested in using together with WLED?

I use Mini NodeMcu like WLED controller + hassOS on odroid XU4 like modbus master+ XY-485 board.
