I am wondering whether anyone has implemented a fake code to disarm shm upon entry by recognizing a known sequence of button presses and/switch activations. The idea is - if door opens while SHM is set to arm you announce on a speaker that the person entering has 60 seconds to disarm the alarm… followed by a sequence of tones. Then WebCore or some other smartapp would check for a known button press (only if in shm disarm mode). Then it would check for next button press and so on. Upon getting the last one correct SHM would be disarmed and the beeps stopped. If a minute passes and that doesn’t happen then play a loud alarm on all speakers, flash the lights, and send a txt to the owner.
At present this is just an idea that I would like to implement because we never use our real alarm system. It doesn’t notify use remotely and is too prone to false alarms and quite frankly we forget to use it. With the above appproach the alarm would be set always when we are gone. Before proceeding I thought I would check to see if anything like this already exists.
