###Actually, isn’t it the other way around???
A keypad, like the IRIS keypad, that is able to arm or disarm the home, is generally kept inside.
Therefore, such a keypad is pretty much useless without a Grace-Periods (i.e., delay detection of intrusions and alarming) for both exiting after inputting the arming code, and after entering before inputting the dis-arming code.
BTW: ActionTiles now has a PIN Protected Tile option, including on our SHM control Tile, but also on Lock, Garage, and even just Switches, in case you’re using a Virtual Switch to control a non-SHM based Alarm, or the Switch is security sensitive for any reason. This makes ActionTiles a “perfect” keypad; except – still need those arm/disarm grace-delays for SHM, please!
And… admittedly, an official ZigBee based keypad would be great if it was supported for fully local (cloud-independent) operation.
