Terrible app. We cannot connect this app to our iPhones. I have gone thru the directions multiple times & continue to get "error". Why is a sprinkler app harder to connect than the thermostat, stereo, car, doorbell or any appliance??? I keep getting various different error messages. Several times it states that the wifi signal is weak, do I want to go ahead. YES. Then it continues with error messages. I have looked at videos and read the trouble shooting page and no joy. Our router is on the wall inside where the railbird panel is outside. Why on earth would I reconfigure my router and add wifi boosters etc. for a sprinkler connection that should be easy? This is insane. The connection should be the easiest of the steps. This purchase was a waste of money. Why all the security steps? The thing need not be NASA secure. If security is an issue for the owner then add those once the app is connected. DO BETTER RAINBIRD
