I've had a TED system for a while. I wanted something that had a few more features, like monitoring graphs that are more pleasing than the very aged TED options. I also wanted something that was more open. I know TED has some APIs that I could use but I liked the look of Open Energy Monitor as I was also building a Open EVSE too.
Anyway, I ordered the EmonPi and a EmonTx from the UK. I got mine and i've had to set it up a little different to the UK way.. since we are on two hots with 120V each in the US over the 240V single fashion in the UK, which the Op Ene Mon comes from. So I've had to use two CTs for the house usage and i've got 1 CT on the incoming solar and doubled it, not perfect until I get another CT to cover the two lines I have coming in from my array of 12 mirco-inverters.
I especially like the Solar usage app that is built in.
you can see the peaks.. during the day my wife plugs in her 6.6kW charging leaf and at night you can see my 3.3kW charging leaf. and I can see the fridge and freeze powering up patterns in there too. along with cooking and other activity.
i tried my hand at putting together some of my own. One thing I wanted to see was the balance between hot line 1 and 2 to see if one leg was getting more usage than the other. Over two days they are within 1.5 kWh. so i have more work do to but the wife has been using the microwave much more than usual over those days and I don't recall if the blender was on the same side as that. though they are short term usage. i did try to guess at balancing the loads between the two lines when I upgraded the panel. maybe a revisit is required?
