If your meter broadcasts your household energy usage, you may be able to use a ~$20 SDR dongle hooked up to a Raspberry Pi to read the kWh of the whole house several times per minute.
There are some little tools that make this easy: https://github.com/bemasher/rtlamr https://github.com/bemasher/rtlamr
You'll need to do a little detective work to separate yours out from the neighbors' but it's not hard.
For my house, I can also read water usage and natural gas the same way by alternating through the relevant frequencies.
