AIRjordan mentioned this in another board. It would be really good to have an add on that would enable an outdoor simple magnetic sensor to be added to the Ring Alarm system. Then offer a Chime/Alarm mode option in the software. I am sure a number of homes and also shops and small commercial properties would appreciate a chime mode for all door sensors and having a waterproof one would be ideal for gates. Range may be a problem but surely Z-Wave with an extender mounted inside the house - maybe near a window - as close as possible should stretch to a front gate.
