I nerded out on this a few years ago and ended up buying a not well known device called a rainforest automation eagle (https://www.rainforestautomation.com/rfa-z114-eagle-200-2/). Its a pretty straight forward little linux device that reads your smart meter (after being enrolled via your utility). It exposes an xml api that I bridge to Prometheus (https://github.com/kklipsch/reagle).

I also bridge my utility (ComEd's) pricing feed to prometheus (https://github.com/kklipsch/comed_exporter). Between those 2 I get pretty good whole home utilization and pricing info graphed into Prometheus (and thus into Grafana).

Could you share how do you combine the hourly cost with wattage readings?

kwh x $

Price is generally a dollar figure for 1000W per hour.

Thanks! Unfortunately all my data readings are in kW. I've been trying to figure out how to get hourly roll-up working and then multiply each hourly reading by price in Prometheus.
