How to monitor energy over time with Kasa EP25P4? Only monitoring current usage right now

Hello all! I am brand new to Home Assistant, having just installed it a couple days ago. I have four TP-Link Kasa Smart WiFi Plug Slim EP25P4, and I have a dashboard set up to monitor the following on each plug:

  • Current (A), Current consumption (W), Today’s consumption (kWh), and Total consumption (kWh).

I have attached relevant screenshots.

But I’d like to actually be able to see these metrics over time. It would be nice to have something like this random Grafana dashboard I found where I could have a card representing each panel in that cool dashboard.

I’m also open to installing Grafana if there is a way “sync” Home Assistant entities to Grafana or something.

I also am totally in the dark on how to use the Energy thing in the sidebar. I don’t have any Shelly devices, but I’ve read that those may be what I want to use instead of these Kasa plugs. I also need to figure out:

  • How to make Home Assistant aware of my electricity charges. I have Evergy as my electricity provider, and they have different rates depending on the time of day. I am currently on their Default Time Based Plan (it’s a Missouri time-based rate plan). I can’t provide a link but it’s here: https://www.evergy.com/landing/missouri-rate-plans

I’m totally new to all of this stuff, so thank you for your patience!

This link to the screenshots shows my 4 x Kasa integration entities, my barebones dashboard showing some metrics from each plug, and this neat Grafana dashboard I found via a google search which is pretty much what I’m going for here.

After that, you might have a look at the PowerCalc integration in HACS, which does a lot of the heavy lifting for you. You don’t necessarily have to buy monitoring devices if the device power rating is known.
