ZigBee could definitely do it but as someone with a lot of smart wall plugs (I have a total of ~40 ZigBee devices in my house) that data is just not really useful because it's just a drop in the bucket compared to cooling/heating/hot water.
One thing that would be more useful and that I really want to get is one of those amp meter for the distribution panel to see my power consumption in realtime: https://www.aliexpress.com/item/1005007038134809.html but I didn't get around to it yet.
