Recently had a solar array put in, and the information available is … lacking… I went looking for an energy monitor, and found several, but the one that caught my eye was eguage.net. Holy crap, $500 ??? Seems like a job for… Arduino!
I’ve seen a number of projects around this, but none seem to directly fit my needs. I think it’ll need to monitor voltage, and then (seperately) monitor current-transducers. Neither should be all that difficult as far as hardware goes. The software could simply post the data to Google Powermeter, or some other API… Ideally I want to monitor (with a seperate CT), every circuit in the house, plus the main, plus the solar production. But I’d be happy with seeing just the main and solar at this point.
Has anybody done something like this?
