There are a couple of features I'd like to see that would greatly enhance setup and trouble shooting. First, during setup or test, there should be a mode where the base can report on the strength of cell signal. If it would simply count out a number from 1 to 5, representing signal strength bars, I could find the optimal placement for the base. Second, I frequently get "door or window open" messages when arming the system. Usually, opening and closing the offending door a time or two clears the error, but to find out which door is the problem I have to log into my online account and refresh my system settings to see which door the base thinks is open. Why not show which doors are open on the keypad?
Bonus suggestion for SS3: Separate the light and speaker function from the base station/cell phone or enable a secondary light/speaker with the option to silence the base. I'd like to put the base upstairs where the signal would be strongest, but we'd never see or hear alerts.
