Helix Fi 2 - Real time Usage Data monitoring

Hello,

I'm looking for a way to tell which device uses how much data at present time. I have over 20 devices at home with IoT, TV, Laptops, PC, etc... and even though I have 500mb internet, it slows down a lot sometimes. So I need to be able to tell which device I should "kick out". Any ideas how this is possible with Helix Fi 2?
