A technology for configuring a lifestyle LED light with a tunable light color temperature is disclosed. The technology of tuning the light color temperature is made possible by blending two LED loads emitting light with different color temperatures thru a light diffuser with an arrangement that a first electric power delivered to a first LED load emitting light with a low color temperature and a second electric power delivered to a second LED load emitting light with a high color temperature are reversely and complementarily adjusted for tuning a diffused light color temperature such that a total light intensity generated by the LED light is kept essentially unchanged.

In one aspect, a method performed at a voice-assistant device includes: while operating in an assistant mode, receiving an occupant command to operate in a monitoring mode; in response to the command, transitioning to operating in the monitoring mode; while operating in the monitoring mode, detecting a sound; obtaining a determination as to whether the sound meets one or more monitoring criteria; and in accordance with a determination that the sound meets the one or more monitoring criteria: obtaining a classification of the sound; and generating an alert or notification in accordance with the classification of the sound.

Various arrangements for handling a potential security situation using a home automation system are presented. A biometric measurement of a user may be received. The biometric measurement of the user may exceed a defined threshold value for the biometric measurement. A security alert from a home automation device in wireless communication with the home automation host system may be received. If the biometric measurement is associated with the security alert, a security response action may be performed.

A two-level LED security light includes an LED load and a motion sensor. The LED load is activated at dusk and deactivated at dawn by a light sensing control unit. At night, the LED load is activated for performing a low level illumination to provide an evening aesthetic and a navigation capacity. When the motion sensor detects any intrusion, the LED load is switched from the low level illumination to a high level illumination for a short duration adjustable by a time setting unit and then returns to the low level illumination. The LED load is configured with one or a plurality of LEDs accommodating to a power source, wherein a voltage V across each LED is confined in a range V.sub.th<V<V.sub.max with V.sub.th being a threshold voltage to turn on the LED and V.sub.max a maximum voltage to avoid damaging the LED.

Techniques are described for enhanced interactions for a security automation system using a doorbell camera. One method includes detecting, by the doorbell camera, an object located within a pre-determined distance from the doorbell camera; identifying, by the doorbell camera, a suggested security action for the security and automation system to perform based at least in part on the detecting; transmitting the suggested action to the security and automation system based at least in part on the identifying; and transmitting, in response to identifying the suggested security action, a message to a user associated with the security automation system regarding the suggested security action.

Various arrangements for handling a potential security situation using a home automation system are presented. During a defined active monitoring time period, a biometric measurement of a user may be received. The biometric measurement of the user may exceed a defined threshold value for the biometric measurement. A security alert from a home automation device in wireless communication with the home automation host system may be received. If the time period between the biometric measurement is within a threshold time period of the security alert being received a security response action may be performed.
