Which smart device is eating my home internet data?

Smart coffee machines, air conditioners and TVs quietly flood home networks with scans and tracking traffic, and ordinary households have no simple way to see which device is doing it or to stop it.

Who has it: Households with a growing pile of smart appliances, and the family member who ends up doing the tech support.

What nothing does yet

A plain language home network watchdog: identify each device by brand, explain in one sentence what it is sending and to whom, flag abnormal volume, and offer one tap fixes such as isolate to a guest network or block tracking only.

Tools that solve this

3 named so far, and where each one stops.

Router apps (Eero, Google Home, Asus)
Show per device usage on some models, rarely explain what the traffic is or block it cleanly.
Pi-hole and NextDNS
Block tracking domains well, but need setup most families will not do.
Firewalla
Strong per device control, but a dedicated box with a learning curve.

How you might build it

01Router integration or small plug in box
02Device fingerprinting
03DNS and flow analysis
04Anomaly detection
05Mobile app with one tap actions
