Abstract: Systems and techniques are described for alerting individuals of HVAC system issues in their home. In some implementations, a monitoring system monitors a property that includes sensors located throughout the property and generates sensor data. A monitor control unit receives thermostat data from a thermostat that indicates activity of the HVAC system and temperature history of the property. The monitor control unit applies the thermostat and the sensor data to an HVAC model that is trained using past sensor data, past thermostat data, past errors of the HVAC system. The monitor control unit determines an error of the HVAC system from the HVAC model output. The monitor control unit determines an action for likely correcting the error of the HVAC system. The monitor control unit provides, for output, data identifying the error of the HVAC system and the action for likely correcting the error of the HVAC system.

Abstract: Methods, systems, and apparatus, including computer programs encoded on a storage device, for performing leak detection. In one aspect, the method includes actions of obtaining water consumption data that is based on first sensor data generated by a connected water meter that is installed at a property, determining, based on the obtained water consumption data, (i) that a water leak is occurring at the property and (ii) a type of water leak that is occurring at the property, in response to determining (i) that a water leak is occurring at the property and (ii) a type of water leak that is occurring at the property, determining, based on a type of water leak that is determined to be occurring at the property, an operation to mitigate potential damages caused by the water leak, and initiating performance of the operation in order to mitigate potential damages caused by the water leak.

Abstract: In some implementations, a system obtains activity data for a sump pump associated with a property where the obtained activity data indicates a present operational status of the sump pump. The system obtains water level data associated with the property where the water level data indicates a level of water within the property, determines that the activity data indicates that the sump pump is operating and that the water level within the property satisfies a water level risk threshold, and, in response to the determination that the activity data indicates that the sump pump is operating and that the water level within the property satisfies a water level risk threshold, provides a notification that the property is at risk of suffering water damage.

Abstract: Some embodiments include a pointer device. The pointer device can include an energy source compartment for coupling to an energy source. The pointer device can also include a light emitting diode (LED) coupled to the energy source compartment and a timer circuit coupled to the LED. The time circuit can be capable of modulating a current driving the LED. The pointer device can include a chassis around the LED and the timer circuit. The point device can include a button coupled to the timer circuit exposed from the chassis. In some embodiments, when the button is pressed, the timer circuit modulates the LED.

Abstract: A method of operating an user input device relative to a projection screen includes: displaying a user interface via a projector in the A/V device; receiving a captured image from a camera tracking a two-dimensional (2D) coordinate of a light source from images of the capture image; displaying a cursor over the user interface via the projector in the A/V device based on the 2D coordinate; detecting an optical pattern from the light source; and activating a click interaction on the user interface at the 2D coordinate based on the optical pattern received.

Abstract: Disclosed is a portable low-power audio-visual (A/V) device including: a housing enclosing a computer board, a projector, a speaker, a power supply and optionally a webcam. The power supply may be one or more power converters connected to a DC battery. The A/V device may include a user interface enabling web browsing with functions including scroll, refresh, home, listing playable/viewable files, and generating a projection screen keyboard. Navigating on the screen can be achieved by a user input system that is calibrated to be used on a projected image, such as an infrared point source.
