Abstract: This disclosure includes techniques for controlling smart home devices upon entering a home with a fingerprint sensor in a doorbell device. After capturing a fingerprint of a digit of a guest and sending the fingerprint to a server device, the server device matches the fingerprint of the digit to an entry in a guest fingerprint database for a first user. The server device sends an operational command to a smart home device separate from the doorbell device and located at a same premises as the doorbell device. In response to receiving the operational command from the server device, the smart home device performs an action corresponding to the operational command.

Abstract: In some examples, a device can control an HVAC system within a building. Includes an analog display including a set of markers, and where each marker of the set of markers corresponds to a respective parameter value of a parameter associated with the building; an electric motor; a pointer connected to the electric motor, where the electric motor is configured to rotate the pointer within a pointer range from a lower limit to an upper limit; and processing circuitry. The processing circuitry is configured to: determine a position of the electric motor while the pointer is positioned at one of the lower limit or the upper limit of the pointer range; and calibrate, a position function corresponding to the electric motor.
