Accessing smart home devices using a fingerprint sensor on a doorbell device

A method comprising:

• detecting, by fingerprint sensor of a doorbell device, a touch input from a first digit of a first guest;
• capturing, by the fingerprint sensor, a representation of a fingerprint of the first digit of the first guest;
• in response to capturing the representation of the fingerprint of the first digit, transmitting, by the doorbell device, the representation of the fingerprint of the first digit to a server device;
• in response to receiving the representation of the fingerprint of the first digit, comparing, by the server device, the representation of the fingerprint of the first digit to one or more entries of a guest fingerprint database for a first user, wherein a profile of the first user includes an association with the doorbell device;
• in response to determining that representation of the fingerprint of the first digit substantially matches a first entry of the guest fingerprint database for the first user, sending an operational command to a smart home device separate from the doorbell device and located at a same premises as the doorbell device;
• and
• in response to receiving the operational command from the server device, performing, by the smart home device, an action corresponding to the operational command.

A non-transitory computer-readable storage medium comprising instructions that, when executed by one or more processors of a server device, cause the one or more processors to:

• receive, from a doorbell device comprising a fingerprint sensor, a representation of a fingerprint of a first digit of a first guest;
• in response to receiving the representation of the fingerprint of the first digit, compare the representation of the fingerprint of the first digit to one or more entries of a guest fingerprint database for a first user, wherein a profile of the first user includes an association with the doorbell device;
• and
• in response to determining that representation of the fingerprint of the first digit substantially matches a first entry of the guest fingerprint database for the first user, send an unlock command to a computerized locking mechanism.
