I have an Ecolink door and window sensor that I wired to the visitor led of a Mighty Mule driveway alarm, similar to this video https://youtu.be/8Mszg0qecgk
It works to send a notification each time the driveway sensor is tripped. The issue I am having is the idle state of the ecolink sensor alternates between open and closed each time the driveway alarm goes off - if the sensor shows closed and a vehicle trips driveway alarm, visitor led light flashes and ecolink alerts open. The ecolink will then show open until the next time a vehicle passes, when then tripped the visitor led flashes the sensor will change to showing closed. With the led flashes at each activation I am getting the notifications, but the way the idle state alternates each time I am not sure how I would ever use a driveway alert to then control an exterior light.
