2. You hate hubs cluttering your good dwelling
Thread does not require a devoted hub. As a substitute, Thread makes use of border routers constructed into gadgets that collectively kind a self-healing mesh community.

Z-Wave is an older good dwelling radio that operates at 900 MHz. Zigbee and Thread function at 2.4GHz. Like Zigbee, Z-Wave gadgets require a devoted hub however are very dependable and expertise much less interference with different gadgets.
Because it does not require a cloud, Z-Wave is standard for totally native good dwelling setups and to run native automations, particularly within the Residence Assistant userbase.
Nevertheless, Matter does not run on Z-Wave, and there are fewer new Z-Wave gadgets in comparison with Thread and Matter.
