I have installed Openhab in raspberrypi and loaded open energy monitoring sketch to arduino UNO.Now,I want to monitor energy in EMONCMS.How to interface serially arduino UNO with raspberry pi so,that without using Ethernet shield I want to transfer my sensors data to EMONCMS
My data flow will be like
SENSORS —> ARDUINO UNO —> RASPBERRY PI ----> EMONCMS.
How to do above data flow in hardware as well in software
Do i need to install EMONCMS in raspberry pi?
