Did anyone install it themselves? I'm not an electrician, but one of my barriers to entry is wiring this in the electrical box. I know the clamps are easy enough to put in there, but I imagine something needs to get power. Anyway, thoughts, suggestions on if this can be done by a non-electrician?
It isn't difficult to install. The most important thing to remember is, TURN OFF THE MAIN BREAKER TO THE PANEL YOU ARE INSTALLING IT IN. If you try to connect the current transformers (CTs) while the circuit is energized you could damage the devices and/or hurt yourself.
They do not have a local API. I don't ever expect them to provide a local API. They are building additional revenue streams by private labeling their products. This is targeted to electrical and mechanical service companies. Keeping the API private and cloud-based allows them to supply that directly to and on behalf of these service companies.
Here is a post from one of the Emporia Energy staff on the subject of local API avilability.
I own a Gen 1 Vue, and I do like the product. I just wish it had a local API. Without a local API its just an interesting toy.
FYI, someone has written a python library to interface with the cloud service. It's called PyemVue. Some others are experimenting with MTTQ connections to the cloud service.
