toUse a Rapberry Pi for your show and put it with your controller. You can then run the show on the Pi and access the Pi over wireless to manage the show. Lots of other ways as well. More than I want to cover in typing.
Put the Pi in bridge mode during the off-season and you can test sequences while creating them by sending E1.31 to the Pi. When ready to play on the Pi, put FPP back in standalone mode, upload your fseq files and play directly on the Pi.
