Keurig smart coffee maker generated 1 TB of traffic in 10 days on a home network

A user going by the nickname Nomad, who has worked in IT for more than ten years, discovered that his parents' smart coffee maker had generated 1 TB of traffic in 10 days. He shared the finding in a post on X on October 6, 2026, and the post quickly went viral.

The coffee maker belongs to his parents, and he does not track which devices they buy. Nomad only helps them remotely with their home network. While checking network activity, he saw that the appliance was using far more traffic than expected.

Traffic stayed on the home network

Most of that traffic stayed inside his parents' home network and did not go out to the internet by the terabyte. According to him, the device clogged his access point, and that was unpleasant.

Exactly what the coffee maker was transmitting remained unknown. Nomad suggested it was a bug in this particular unit and did not dig any deeper.

The decision about a new coffee maker

He disconnected the device from the network and did not want to keep an IoT gadget connected that was capable of malfunctioning like that and clogging the channel. In the end, Nomad decided to buy his parents a new coffee maker.
