    Abstract: An IAQ sensor module includes: a sensor configured to measure an amount of an item in air, the item being one of particulate matter, volatile organic compounds, and carbon dioxide; a minimum module configured to selectively store the amount of the item as a minimum value of the amount when a mitigation device has been on for at least a predetermined period, the mitigation device being configured to decrease the amount of the item in the air when on; a storing module configured to selectively store the minimum value as an initial minimum value; an offset module configured to determine a drift offset for the sensor based on a difference between the minimum value and the initial minimum value; and an adjustment module configured to determine an adjusted amount of the item in the air at the IAQ sensor module based on the amount and the drift offset.

    Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for advanced monitoring of an HVAC system. In some implementations, a voltage measurement across at least two interface terminals of a thermostat that controls an HVAC system of a property is obtained. The voltage measurements are analyzed. A likely power cycling activity of a component of the HVAC system is determined based on analyzing the voltage measurements. Whether the HVAC system is operating properly is determined based on the likely power cycling activity of the component of the HVAC system. Data indicating whether the HVAC system is operating properly is generated and outputted based on determining whether the HVAC system is operating properly.

    Abstract: There are disclosed systems and methods for managing object configurations within a structure. For one embodiment, a fixed object profile including dimensions and locations of ventilation of a building space and a non-fixed object profile including dimensions and a location of a non-fixed object are identified. One or more contaminant risk locations of the building space are determined in response to determining the air flow within the building space associated with an HVAC unit. The air flow is determined based on incoming air flow streams to the building space and outgoing air flow streams away from the building space. One or more object positions are provided at an output device based on the contaminant risk location(s). For another embodiment, the contaminant risk location(s) are selected from possible people locations. A person position is displayed at an output device, in proximity to the building space, based on the contaminant risk location(s).

    Abstract: A method and system for monitoring using a sub-slab sensor assembly for a building having a slab includes a housing, a first air quality sensor coupled to the housing and generating a first air quality signal for air above the slab, a second air quality sensor coupled to the housing and generating a second air quality signal for air below the slab and a pressure sensor coupled to the housing. The pressure sensor generates a pressure signal corresponding to the pressure below the slab. A position sensor generates a position signal corresponding to a location of the sensor. A network interface communicates the first air quality signal, the second air quality signal or the pressure signal, or warning signals corresponding thereto and the position signal to a network.
