Hi, new user here.
I was brought here after seeing the cost of the Smappee & Sense monitors only to see the price of an emonPi setup is pretty much the same, if not more. So I have of course now started looking at the DIY option.
I have read through most of the pages on learn.openenergymonitor.org now and using an arduino and sensors I should be able to get most of what I want or live energy monitoring. I dont need solar or temp monitoring etc, and this is all very low cost. So I’m confused as to where the Pi comes in on the EmonPi, do you really need a Pi? If it’s just for posting data via a network connection can you not use an ESP8266 based arduino?
Also, and I’m not bashing the price of the EmonPi as I’m sure its justified, but compared to an Arduino, Pi, and sensors it does seem pricey. What does the EmonPi PCB give you that that the home brewer cant do?
