Lighting Tutorial - Controllers 

Part 10 in my series walking through various elements of my holiday lighting show and setup: here's how I control and run my show.
High level, it's all run off FPP (Falcon Pi Player) using the Master and Remote synchronization functionality. In the garage sits my main "Master" controller: a Raspberry Pi that contains all the music and full sequences. It pumps out the audio to a sound card and the FM transmitter (see "FM Audio" tutorial part) - and it also sends out timing for all the remote FPP's to synchronize their portion of the overall sequence. In the same box in the garage, I have a Kulp K40D-PB that is a "Differential Controller". Most of my lawn props are controlled via this.
The boxes throughout the yard (4-5 depending on the props) all contain "Differential Receivers" and receive signal from the main K40 via ethernet cabling. I chose this method to ensure an always-stable connection and not worry about exterior wifi.
My roofline I wanted a standalone box since I light my eaves other times throughout the year. So, this box contains a Kulp K8-PB. It can either run as Master (for single holidays during the year) or as Remote (for main holiday show at end of the year). This syncs via wifi (which I admittedly had to fiddle with router placement for an always-stable connection).
