So the problem as I have an ADT model is that arming and disarming from the panel or the ADT FOB only arms and disarms the ADT sensors, which I have found to be problematic on several levels. the front panel, nor the FOB arm and disarm the SHM part of smartthings.
First the ADT sensors, if they go offline, even at 2 in the morning cause the ADT hub to sit there and beep until you resolve the problem. Bypassing the sensor at the hub does not stop the beep for long.
Second I am finding that the ADT sensors kill batteries rather quickly. I have had to replace batteries in two motion sensors already, one of them twice since bringing the system online just a few months ago.
This makes me want to get away from the ADT part of smartthings and use the sensors of my choice, which I am already using in the form of smoke, and water sensors.
