I am new to Smartthings and so far very impressed at the skill and knowledge across the community. I am in the middle of implementing a security system using ST with motion sensors and door switches. It seems to me some basic functionality might be in order for the Smartapp: Smart Home Monitor - Security in the following areas:
The smart app does not have the means to create a zone (or sensor) with a delay function. The delay function could be programable in seconds or minutes and would allow a person to either enter a particular zone (front door) and give them time to disable the alarm. Perhaps all the sensor types could have a delay option?
A delay zone mentioned above should also have something like a pre-alarm. On traditional alarm systems when someone enters a zone with a delay function a pre-alarm may sound immediately until the delay has expired and then the alarm siren sounds at that point. Often pre-alarms are built into a key pad and are something on the order of a piezo (not too loud but loud enough to wake you or be heard at the other end of the house).
The smart app Smart Home Monitor - Security has the ability to turn a light on. This might be the easiest place to plug in a Zigbee or Zwave outlet which for a simple example might have a wart type transformer and piezo wired to it used specifically for the pre-alarm sound. SO some functionality and timing parameters would have to be developed (turn it on, look for unarm command, otherwise count down and expire) at that point the siren would be enabled but as you can see some orchestration is needed between these functionalities.
I would love to continue the dialogue here to see where this might go. At the same time if I missed something of significance (it exists already dummy, wrong thread or otherwise I apologize profusely)
