Anybody using a whole-home energy monitor yet (Sense, CURB, etc)?

I remember Neurio was one of the first a few years back, and it was discussed here. It is now defunct, which is yet another example of how much disarray the smart home market is in and why it sucks that we usually have to rely on "the cloud" or some company to continue existing and supporting a product.

I just ran across IoTaWatt, which is an open platform that doesn't rely on any particular company or cloud service to operate. It logs data locally, so you can just use it standalone if you like. Looks like it can also send data to arbitrary time series database systems, local or cloud-based. It also has 14 channels, so you can monitor the mains and individual circuits, and it'll work with just about any off the shelf CT.

There's no machine learning, no cloud required (though you can set it up), nothing fancy. Just per-circuit usage data that you can do with as you want. I guess I would just want to set up a notification if my AC or fridge is doing anything abnormal, and then glance at a report every couple of weeks to see if anything crazy is happening with my non-AC power use. If I think of other things to automate down the road based on the data, I'd just add as I go. And not worry about yet another tech company going under and bricking it.
