Man there are way too many IoT standards. What's the difference between these two? How do they each compare to Matter?
An important difference between thread and zigbee/wi-fi I'm not seeing mentioned is that all thread devices automesh in a hub/spoke model as long as they're not battery powered. So your light bulbs, plugs, etc all become extenders and part of a self healing mesh network without a single point of failure. For me it works better than Zigbee for this reason.
Zigbee does that too tho, right?
The wiki on zigbee says so at least
Yes, Thread serves similar functionality to Zigbee, to the extent that some people describe it as Zigbee 2.0.
However it’s a new protocol for a new standard, that has backing from all the big names in home automation, including Apple, Amazon, Google.
Zigbee is a great protocol. Thread will bring better connectivity for the future (we hope)
Pretty sure than an underlying feature of both zigbee and zwave.
They're different in their implementation. Zigbee automesh is more of a centralized router-hub model with self healing relying on routing tables. This caused significant issues for me. Thread is true automesh with all devices acting as a hub in a hub/spoke model, so there's no centralized routing table to act as a single point of failure.
