         | This apparently allows to have an RPi act like a lamp-type
         | device in that protocol, with control over the GPIOs

           | Matter came around after I left, but I believe it is the same
           | as CHIP: * IEEE 802.15.4 (2.4 GHz PHY/MAC) * 6LowPAN (IPv6
           | for constrained devies) * Thread (Mesh network layer) * UDP
           | or CoAP (CoAP is like http for connectionless networks)
           | 
           | You need a bridge to connect CHIP to the internet (e.g. Apple
           | Home). It was cool to route IP packets directly to lightbulbs
           | from aws, but we don't bridge the networks in practice and
           | all incoming/outgoing traffic goes through the bridge
           | application.

             | Matter is the protocol running on top of IP, so it runs
             | over Ethernet in the example (since the Pi doesn't speak
