BTW, why do you need Tbps speed network for home automation, except for video surveillance? A QoS guarantee in the order of 10s or 100s of milliseconds in latency will suffice, right? That should be easily achievable with a relatively slow speed *dedicated* network with only sensors and switches. The google Nest Protect (smoke/CO alarm) is using such a dedicated network to talk with other monitors in house; interestingly even the wired version of Nest Protect is not using the common interconnect yellow wire.
