Name your Commtel entry system such as "Front Gate" or "Rear Gate". Store multiple named Commtel entry systems in your smartphone and send each command SMS to the appropriate telephone number carrying the appropriate login code.
See what you are controlling at a glance by renaming your relays such as "Relay 1" to "Vehicle gate" and "Relay 2" to "Pedestrian gate", then have your smartphone translate and format those into the appropriate Commtel entry system SMS commands.
Pull in telephone numbers from your address book to use within command SMSes for the Call Buttons and Authorised Numbers of your Commtel entry system.
