Hi folks. I am the design engineer of the Lighthouse Controller and will try and answer your question.
There is no alarm or cell phone calling feature as you describe. However, in Version 2.0 you can access a raw data dump of every parameter in the controller like current ph, light status, history, etc. If you have your own server or are internet savvy, you could write a server-side script to get this data and do anything you need to do with it (like send emails out on certain values, dial phone numbers, or whatever).
