Abstract
Methods and systems are described for determining operation of an openable barrier into a building. A method for determining a state of a barrier includes identifying, based at least in part on a barrier sensor, a first position of the barrier. In one embodiment, the barrier sensor may be positioned at a first side of the barrier, and a magnet may be positioned adjacent to the barrier sensor at the first side of the barrier. The magnet may be positioned at an angle with respect to the barrier sensor. The method may further include determining, based at least in part on the barrier sensor and the magnet, when the barrier changes position from the first position to a second position; and wirelessly transmitting data concerning the change in position of the barrier.
