I bought an RTL-SDR dongle years ago thinking I was going to do all sorts of awesome things with it. After my initial screwing around with it, it landed in a drawer for a few years.
Well a couple of months ago I found this[1] and hacked together my own daemon to read my power meter and publish the result via MQTT. I then wrote a couple of sensors in Home Assistant to estimate my upcoming electric bill and the instantaneous power draw of my house.
It's been rock solid so far. I've been surprised how much energy I use while sleeping in the middle of the night (something like 350W)
