GoKawiilSmart coffee maker found generating 1TB of local network traffic in 10 days
An IT professional named Nomad discovered his parents' smart coffee maker had generated 1TB of data traffic over 10 days while monitoring their home network remotely. Most of the traffic stayed within the home network rather than going out to the internet, but it was enough to overwhelm part of their Wi-Fi access point. Nomad attributed the issue to a likely bug in the device and decided to disconnect it rather than investigate further.
GoKawiil's interpretation of the reporting above, not reported fact.
The incident highlights how poorly-behaved IoT devices can silently strain home networks even without sending data externally, a risk many users would never notice without technical monitoring. It suggests smart appliances may ship with software bugs that go undetected because few owners inspect their network traffic, raising questions about quality control in connected home devices broadly.
- A smart coffee maker generated 1TB of traffic within a home network over 10 days.
- The traffic largely stayed local but still saturated the household's Wi-Fi access point.
- The owner decided to disconnect the device rather than investigate the suspected bug further.
