Terrible app, need to get new developers that know what they are doing! Have had this system for over 4 years and never had good experience with it. It's mostly good except for the connectivity problem which makes the product useless, if you could resolve the problem with the app connecting to the controller you would have a great product. When I started up the system this year I have not been able to connect the app with the controller as usual so I have decided to go with a different product, I really liked the app when it worked but to much work and time to get it to work!
