@SteveH posted:As far as I'm aware, all Lion Chief locomotives when powered by the track will go into some kind of standby mode. The only ways I'm aware of to stop this are to either connect them to the remote/bluetooth app or disconnect track power. But, my personal experience does not extend to LC 2.0, so maybe there is a way to turn off smoke remotely, besides with the physical switch on the loco.
The Lionel BT app does have smoke control for the BT locomotives, it works fine for my LC+ 2.0 0-6-0T switchers.
