Device Power Meter feature - only in-app? Why suggested in web?

[SperlingJason]

I requested this in the Product Wish List, and was told it’s on the agenda for this year:

Add device metering on website

On the app, when I open the device there is a usage chart (showing usage by day/wk.month/yr) and a power meter chart (showing the second by second impact of the device on the power meter). Unfortunately, on the web app I am only seeing the usage chart and not the power meter chart. I would like to have the power meter chart included at the device level when I am logged into the web page on my computer.
