Intelligent door lock system with faceplate and/or ring electrically isolated from circuit

An intelligent door lock system at a dwelling, comprising:

• a position sensing device configured to be coupled to a drive shaft of a lock device, the position sensing device sensing position of the drive shaft to assist in locking and unlocking a lock of a lock device;
• an engine with a memory coupled to the position sensing device, the engine configured to execute software instructions relative to the positioning sensing device;
• a circuit that electrically couples the position sensing device to the engine;
• a faceplate and a ring, with the lock device at least partially positioned in an interior defined by the faceplate and, wherein at least one of the ring and the faceplate is electrically isolated from a circuit;
• an energy source coupled to the circuit;
• a device that converts energy into mechanical energy coupled to the circuit, position sensing device and the drive shaft, the device that converts energy being coupled to the energy source to receive energy from the energy source, wherein the circuit electrically couples the device that converts energy into mechanical energy to the position sensing device;
• and
• wherein a mobile device at an interior or exterior of the dwelling configured to provide locking or unlocking of the lock, the intelligent door lock system configured to allow controlled access to the dwelling that includes an occupant of the dwelling as well as a designated third person granted access rights by the occupant.
