    Edit... I'm pretty sure something is miswired. Like, not only are the phases mixed up on the consumption CT's, but they are facing backwards or have the leads reversed, too.

    trouble with enphase envoy consumption measurements

    So I'm having a hell of a time with my enphase envoy consumption measurements. Specifically it has to do with the power factor. I've got the old (non-IQ) version of the envoy. My consumption only power-factor when I look at it from the installer toolkit says around 1.0, but the apparent power is nearly double the watt measurement which implies a pf of around 0.5. When I investigate the raw numbers from interrogating the envoy direcly it actually shows me the low power factor. There's simply no way I have a power factor of 0.52 in the house. I've tried switching polarity on the CTs, and moving them around, but I can't get it into a real range. I'm wondering if someone with a functioning pre-IQ envoy could browse the production json value and post your results. Here's what mine looks like:

    (browse to <envoyIP>/production.json )
