I really like the idea of an open, local standard for this stuff. I have been a little annoyed at the matter standards immaturity still. Two things I’ve noticed is that there’s not good support for very low power devices that use WiFi. What you’d like to do, for example for a battery powered sensor, is to go into deep sleep and disconnect from the WiFi and then wake up periodically and report the sensor reading. Unfo…
I've seen somebody on Reddit using LoRa stuff for the home. The problem with these wifi based sensors is that you eventually run out of IP addresses (yes you could get fancy with subnet setup but still). Another problem is that at some point you might want to swap routers -- I had to swap out a faulty Netgear router, and the re-set was a major PITA. For these reasons I've been moving to Zigbee.
Bandwidth and interference will likely be an issue far before ip scarcity.
