Update Feb 2019:
Glad to see everyone excited (and anxious) about this. I just ordered this. Going in vacation condo which will never get wired so mesh is my best bet to cover the dead spots. Have been using old ST Hub but only a few devices currently, and I just added about 10 more in a re-model including 6 nest protect and 5 Stelpro Z-Wave Plus KI STZW402WB+. So I will be ok starting from scratch.
Questions (I know, I already ordered the thing. . .!)
Big question (this will expose my IT ignorance. . .) Can I just plug the new Samsung network into my new Netgear CM500 modem and expect it to fire up as a router (i.e., I don’t need a router as well?)
Answer: With Plume app, this is possible.
And if I want to feed a gig switch, can I plug the switch into the one ethernet “out” port on the primary Samsung device that is plugged into the modem? The modem and primary Samsung device sit in an entertainment center which has multiple devices that would love a direct ethernet cable (Apple TV, Vizio TV, receiver, etc.) Am probably going to see how everything goes just over wireless first to avoid yet another device. But I can imagine that if the Apple TV is streaming a movie in 4K, someone in another part of the house might gripe that all the bandwidth is gone.
Answer: Feeding a switch from the ST hub is no trouble.
And finally, will the “ethernet out” port on the extension units feed a TV or other device as though it is wired directly to the network?
Answer: I haven’t tried this yet, but assume that’s how it will go. Although since the mesh network is so spectacularly good, I think you could probably use wifi for almost everything.
Thanks for the help. I will post the outcomes of this project in about a week. (update Feb 2019 - took a while to figure it all out!)
