  • Decoding an alarm output flash pattern

    Hello All,
    I am using a Raspberry Pi connected to a gate opener. One of the inputs to the RPi is an alarm output from the gate opener that flashes a certain pattern to indicate the alarm type. I am using Spud's RPi plugin to read the inputs. The timer resolution in HS3 is only to the nearest second. I need better resolution to decode the pattern. For example, One alarm is 1 quick flash, and a pause. A different alarm might be two quick flashes and a pause. Another alarm might be 1 long flash and 3 quick flashes. Can this be done with a script instead of using the events in HS3? Thanks for your help.
