1. A smart dehum circuit for powering a chime that outputs audio in response to detection of a trigger event by a video doorbell, the circuit comprising:
a detector circuit configured to generate a power signal in response to determining that an output voltage signal of a first circuit exceeds a threshold voltage; and
a microcontroller coupled to the detector circuit, the microcontroller being configured to:
generate a chime power signal based on the power signal of the detector circuit wherein the chime power signal is generated to power the chime in response to detection of the trigger event by the video doorbell; and
determine, based on a timing logic of the microcontroller, that the chime is an electronic chime in response to determining that the chime power signal satisfies a first time threshold.
