@Macstered - I'm hoping you have provided product feedback via the Deco App you use to manage your devices.  If the TP-Link receives many requests via that route, then perhaps utilisation reports by device (e.g. last minute, last five minutes, last hour, last day, last week, last month, user-defined range) may be more likely to appear in the future.

  @RiBr I have no idea where to do that in app. I was under the impression using this forum was where the request should go. Also this has been requested for YEARS it seems. If this (VERY common) functionality is a blind spot to TP-Link then shame on their product managers. 

  @ShaGo - it was under "support center" from the hamburger menu, but I've checked just now and the ability to submit a feature request (or contact support) seems to have gone away - it is now just full of FAQs.  If you search for "utilisation", it says "no results found" and suggests contacting technical support - but doesn't provide an option of how.

Perhaps I need to try again during US business hours to see if I get a different result.  That said, the response I got from my feature request was from support.uk@tp-link.com with a ticket number and the following text:
