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

Energy

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.

I’m curious how you got those plugs to show you power usage. I was able to add my plugs, but don’t see the A/W/kWh. Did I miss a step in the addition process? I’d appreciate any links/pointers on how to get those stats to show up. The plugs are on a separate LAN where they DO NOT have access to Kasa cloud, but I did use the Kasa app to set them up initially (without adding them to iHome).
