I just have the bluetooth motor that came with the Powered Up Batmobile that I plan to put in the train.
I want to use IFTTT to either press a button or issue a voice command that will turn on all the christmas lights in the house, play a playlist on spotify and start the train.
It's easy to do the lights and music, the difficult be is finding a way to issue a command to establish a bluetooth connection (or wake it) and then set the train at a continuous speed until the button is pressed again.
