Oooh, I've been wanting something like this for some time. Prior searches have only turned up systems far, far larger and more complex than a house needs.

I installed it last year. Very happy.

Looks nice, sad that there is no 3-phase version

I've been considering an Emporia Vue 2 for a while now. It would end up being about half the price of this. Does anyone know anything about it? I'd like to go open source, but my primary motivation is lowering power costs, so its hard to justify doubling my ROI time.

It works with three phase.

There are two ways to do it.

Either, one clamp, and it calculates the other two, or you can use three clamps.

InfluxDB integration? Mains, branches and my solar inverter? If I had 3-phase, it would do that too?!

Very slick! I've ordered one.

How many clamps are you using?

I'm not well-versed in this field but had heard of the Sense, and was almost going to buy one, except I detest that it's closed off to everything but the cloud. Furthermore, I've heard the mains-only monitoring it uses, while trying to divine the power sinks by their signature, leaves much to be desired. This looks like just the thing for me.
