I’m looking for a very basic setup and have the following components.
I’ve built the EmonCMS and got it working on a RPI 3 just fine, and I was hoping I could just connect an optical sensor to the RJ45 jack in 2 locations.
My solar meter is in my basement next to the inverters. It is an Itron CL200 and I i confirmed it has a pulsing LED on top.
My net meter is outside (other side of the house) and is a GE Kv2c and again has a pulsing led.
My basic requirement is to just monitor both of these with optical pulse sensors; not looking to use CTs at this time.
Can I do that with just 2 raspberry pi 3’s talking over wifi and the pulse sensors or do I need to buy an emonpi (and / or other things?)
Down the road I might want to also tap into the api and figure out how to log my natural gas meter. It is an itron of some sort and I’ve been able to capture the rf signal for my unit with an rtl-sdr dongle and rtlamr.
