Keurig smart coffee maker reportedly uploaded 1TB over home Wi-Fi in 10 days
An IT professional reported that his parents’ Keurig K-Supreme SMART coffee maker transferred about 1TB over their home Wi-Fi in 10 days. A UniFi screenshot showed roughly 1,008GB uploaded and 9.94GB downloaded, which was enough to saturate an access point. He suspected a bug, and restarting the machine appeared to fix the problem.
The coffee maker was identified as a K-Supreme SMART with BrewID, a model that supports app-based remote brewing, scheduling, power control, and voice assistants. It connects over 2.4GHz Wi-Fi, which limits throughput but still can carry substantial traffic. The UniFi record showed about 9.94GB downloaded and 1,008.45GB uploaded across roughly ten days.
The person who reported it, an experienced IT specialist, noticed the issue after his parents reported slow network performance. He later concluded much of the traffic likely stayed local, rebooted the machine, and moved it to a segregated VLAN. He avoided packet capture and recommended Keurig address a possible network-stack flaw.
This incident may heighten concerns about always-connected appliances in homes. Households with smart coffee makers and similar gadgets could face unexplained bandwidth use, slower Wi-Fi, and privacy worries if devices transmit unexpectedly. Manufacturers may face pressure to improve diagnostics, default limits, and local-network controls. IT-savvy users might isolate such devices on separate networks, while less technical consumers could remain unaware until performance suffers. It could also prompt broader scrutiny of how much data everyday appliances generate.
