- Sat May 30, 2015 5:40 am #18950 Hello,
I would like to implement an energy meter wifi low cost, to measure the electrical parameters as KWh,V,A,W,Hz,pf....
I attach the schematic my project, and datasheets of energy meter Modbus RTU.
You see in this small project the possibility of making bussines?
We want to implement this project together?

- Mon Jul 13, 2015 4:38 am #23122 @Aledav, have you got any update on this project? I would like to implement it with the Arduino-based IDE. But I have no previous experience with MODBUS/RS485.

Before shopping for the needed hardware I would appreciate a hint on go/nogo

Thanks.

I'll give you a hand to develop this if you give me the nod and some time to get the parts together. I can do the code if its doable.

Found nothing on ebay but maybe ali
This seems good for 240 Volt
