I think I've just decided to leave DCS wifi out of my layout control system. I was headed that way. I have a relatively small layout--still not even 25% complete--in a 17x16 island-style design in a U shape. I won't be giving any tours or even having people over much. And I don't think anyone will be downloading even the free DCS app into their cell phones to run my trains.
I am running 3 TIUs and 2 remotes with 12 blocks of DCS or TMCC command control. I don't expect to run any conventional control trains. I am running TMCC and CAB1 because I don't expect to ever be able to afford a stable of Legacy engines. Since a DCS remote and a DCS WIU ave about the same street price, and since I need a WIU for every TIU, why bother? Why not just spend the money on another remote or two and call it done.
I think DCS wifi is like heated seats in your car. Nice fora couple days in the winter but....really?
