Adding dynamic property, using static or global vars?

I’d look to handling this in the code of the app rather than in the devise type.

What I would look at doing is subscribing to when the sensor is opened and closed. When it’s opened use change a state variable to false, and then when close run a procedure in a minute to change the state.

Something like this:

def doorSensorOpen(evt) {
     state.doorClosed = false
     }

When the door opens, we change the state variable to false.

def doorSensorsClose(evt) {
     runIn(60, closeState)
     }

def closeState() {
     state.doorClosed = true
     }

What this does is when the door closes, it schedule the ‘closeState’ procedure to run in 60 seconds. This gives a 1 minute for the accelerator time to stop moving.

Then in your procedure where you run the actions when acceleration happens, put in a conditional:

def accelerationCheck {
     if (state.doorClosed = true) {
          Insert you code to do stuff here
     }
}

That way you need acceleration AND the variable needs to say closed. And that won’t say closed until the door has been closed for at least a minute.
