Is your feature request related to a problem? Please describe.
No

"I use the HomeWizard app to track the usage of a specific device. Now I actually want to rebuild this in Home Assistant. What I find particularly useful is the graph and the usage over a period of time. But at the bottom, you can adjust it per day/week/month/year and 'now'.

When I look in Home Assistant at the energy cards and this card, there are the energy date selection card and the device energy graph, but unfortunately, I can't link one device to it.

I can set a max device, but this only shows the largest consumer and therefore not a specific device."

I would love to see this added here...
So i can track one device... instead of all my energy
