I have no experience with SprinklerAce however my mobile app will work out of the box now. If you don’t wish to install the mobile app you can simply use the version hosted on Rays website (requires a port forward but gives you access anywhere) available here: http://rayshobby.net/apps/sprinklers/

If you want it running on your Pi (which brings extra features such as logging) you can follow the instructions on my Github page here: https://github.com/salbahra/OpenSprinkler-Controller
