Two layers, one confusing conversation

Protocol discussions go wrong because people compare things at different levels. It helps to separate them.

Network layers decide how devices physically talk: Wi-Fi, Thread, Zigbee and Z-Wave. They determine power consumption, range, whether you need a hub, and how many devices your network can carry.

Application standards decide what a device says: Matter is the important one here. It is a shared language that lets a device work in Apple Home, Google Home, Alexa and SmartThings at once, regardless of which network it uses.

So "Matter or Zigbee?" is not a real choice. Matter is what you want written on the box; Thread, Wi-Fi or Zigbee is how the device gets there.
