Abstract
Doors such as garage doors can be automated by pushing commands to a removable device attached to the garage door. The state of the door (e.g. whether the door is open or closed) may be obtained from a position sensor located within a removable device. An implementation may indicate, over a wireless network, the state of the door to a user. The user may send a command to a wireless transmitter located within the device to change the state of the door. An implementation may also send a signal to the door to change the state of the door.
