This is a universal tutorial about setting the time of use billing template in the Home Assistant. It does not ask to use a specific brand of energy meter.

Very interesting! Can I use an energy meter connected directly to an outlet as well? I want to see individual devices giving readings of power and energy.

Of course, this tutorial does not ask to use a specific brand device,what you need to do is just replace the hardware in tutorial with yours

Could you give me an example of a zigbee or z-wave energy meter (connected to an outlet) that could be used? These systems seems to be mostly available here in Sweden where I live.
