Glad to be here!
My goal is to build smart energy monitor, that can read real time data from energy meter via RS485 and send them thru ethernet to virtual cloud (emoncms.org), to store and show everything in graph.
I have Arduino UNO, ethernet shield, RS485, LCD display Serial IIC/I2C/TWI 2004 20X4 Character, RTC (real time clock) and eletricity meter DINmetering with impulse ports.
I have put them together and done some small projects but now I want to build energy monitor.
Have anyone written same code for this? Have same tips? Some projects are similar but they are slightly different.
