I've had a string of in-home energy monitors, and I've turned on all the relevent features for this, but at this point, I have disconnected everything from the internet to stop it being enshittified, and my local incumbent energy transmission provider has left all the consumer-facing smart meter services rot on the vine while the state of Texas kneecaps all the legislation that made it possible in the first place.
In short, all the industry and government entities involved have given up on the consumer here and have pissed it all away, and it's a shame.
