An investigation by Gamers Nexus found LG smart TVs sweep local networks to map phones and nearby devices. Tests also showed the sets can capture microphone audio with the screen off — they then upload data once reconnected to the internet.

Yup, this can get used for very scary stuff. As you said it’s low bandwidth, but since edge devices are more powerful that’s less of a limitation than you might think. A TV could easily do speech to text, rough ACR, and device fingerprinting all locally without any internet connection, then summarize and compress that data for a daily or weekly upload. No need to send the large data itself, just a a small report that’s a few KB in size.
