PiRelay is an app with works with a Raspberry Pi running the PiRelay software to toggle the GPIO pins on up to 5 Raspberry Pi's for switching up to 100 Relays.

This is the v2 project of the massively popular 'Pi Relay Pro' app and v2 now comes as a Free Trial allowing you to have up to 10 App Launch's to try it out before you buy, with an in app purchase to remove the trial.

This app could be used to control virtually anything that requires an electronic switch to operate, such as to Switch On/Off Lights, Open/Close Electronic Garage Doors, Open/Close Gates, Heating, Cooling etc.. or anything else you can think of that you might want to control.

IMPORTANT NOTE: You must follow the instructions to install PiRelay onto your Raspberry Pi before this app will work for you.
