Control Da-lite screen and Chief projector lift

[scotsman]

I am installing a Da-lite drop-down screen and a Chief SL236 projector lift in my ceiling.

I want to hit a button on my phone that would cause the screen to drop, the lift to drop and the projector to come on.
 
Looks like the Da-lite screen has a 110V connected to the up/down/stop switch. The Chief projector lift uses a low voltage wall switch.
 
Any suggestions? Thanks!
