@davepeck now here is an idea! Indeed the air quality monitor is not directly accessible from the public internet. I guess I need to unpack some network debug tools, and seriously rethink just how “private” a #safari #private tab is if it moves local traffic that only traverses my house LAN to the public internet, and I don’t care how encrypted it is.
@J12t @davepeck my best guess is that it would forward anything through the gateway's known MAC to avoid someone on the LAN from snooping on you through ARP-based attacks.
One way to test could be to add a static ARP entry for your device's IP pointing at your router's MAC and see if it replicates the before you're seeing...
EDIT: I missed "iPad". Packet dump from your router if that's possible...
