Ability to add a external sensor!
Ability to add a external sensor such as door switch. That would be great for a boat. I heard vibration sensor is not sensitive enough to send an alert if someone climbs on my boat while on the trailer in a parking lot. Its hard to find a boat alarm with enough range for hotels. It would be a huge seller!!!
Bring back a device Similar to the HUG that has sensor to detect water or Fire in a boat.
