I honestly haven't tried those products, but what I don't see is the ability to have remotes control switches (or plug-in lamp modules) without needing to use a controller. Caseta allows this because there is a pairing process that just involves the remote and the switch. I'm not aware of any similar Z-Wave or Zigbee thing, but it would certainly be cool if those existed and honestly would make me reconsider Z-Wave/Zigbee if I was redoing my system.
