Monitoring Home Power Consumption for less than $25

As I considered how I could accomplish this task, I came to a realization. At least where I live, I haven't seen a "meter reader" in at least a couple of decades. This meant at least once a month, the power company was somehow retrieving my usage in an automated fashion.

Some research told me that the power company accomplishes this via a simple radio broadcast on the 900Mhz spectrum. Once again, it was a task for the RTL-SDR that I use for a number of projects.

The RTL-SDR is just a cheap software-defined radio that can be had for less than $25 on Amazon with an antenna. It can used for everything from monitoring cheap temperature and humidity sensors, tracking airplanes, and apparently, reading my own power meter.

This is super cool and I might have to try this. I know our house has a wireless meter system, the electric company installed it several years ago. I've never looked into how it works but if it’s this easy this could be a great way to get much more detail on our power usage. If you can get hourly, daily reports on power you should be able to connect your activities close enough to make changes to reduce usage.

On almost a daily basis, I am bombarded with ads on Facebook for the Sense. This device allows you to monitor whole-home power consumption. I could probably find room for such a device in the budget, but I HATE electricity. Too many years of geeky endeavors have resulted in far

Not to mention, I always waste a ton of time fighting with Grafana trying to get it to even report "sane" numbers.
