Interesting. The Wyze app on my iPad shows me the MAC addresses of all my cameras, which correspond to the MAC addresses I view using FING on Android phone or browsing my router using Safari and Firefox on my Mac desktop.
I think what you’re reading is Apple blocking the MAC address of their devices on the internet, which can be used for tracking. In the iOS WiFi settings there is an option to generate a “private” address to fool trackers. Turning it on can also block the device from your local network if you use MAC filtering on your router. FING and my router report the correct MAC for my iThings as I don’t have the privacy option flipped when I’m connected to my home network.
chrisjost answered my original question, FING is trying to figure out what type of device is being monitored using their own LUT. I was concerned that maybe Wyze was up to something with Google, but apparently not.
