GeoReaction was designed with Home Automation in mind. That isnt to say that you cannot use it for other specific needs. Most Home Automation systems allow access to the system via restful services. Using these restful services in combination with GeoReaction you give your home the ability to be location aware of its occupants. This means that you can setup multiple reactions to let your Home Automation unit know when you are headed home from the office, when you are so far from your home and when you arrive home so that you can make each step in that process have a purpose in your Home Automation setting. For instance, when you leave your home you can have a reaction that post your absence to the Home Automation system forcing your home to shut off any lights that were left on, or turn on your outside lights so you can see your home upon arrival, etc... The uses for this app are endless and there will be many more improvements to make this your most useful app you never touch because it just works behind the scenes. Additionally, you have full control of your GeoReactions with a swipe, perform a swipe on the cell and deactivate or activate a certain reaction on the fly.
