Various arrangements for assessing an installation of a smart home device are presented. An orientation of the smart home device may be analyzed to determine whether the orientation of the smart home device is unsuitable for one or more features of the smart home device to function properly. An indication of whether the orientation of the smart home device is unsuitable may be output, such as by the smart home device using voice or lighting.

An exhaust fan configured to exhaust air from a building includes a housing, a fan, and a motor for driving the fan. Overlying the fan is one or more dampers that are moveable from a closed position to an open position. Underlying the dampers is at least one pivot arm per damper that is pivotally connected to the fan and which normally assumes a horizontal position spaced from the overlying damper. A mechanical fusible link is connected to the pivot arm and is configured to break in response to a buildup of heat in and around the dampers. Once the fusible link breaks, then the pivot arm is operative to engage and open the overlying damper.

Various methods and systems for smart home devices are presented. Such smart home devices may include one or more environmental sensors that are configured to detect the presence of one or more environmental conditions. Such smart home devices may include a light comprising a plurality of lighting elements. Such a light may be configured to illuminate using a plurality of colors and, possibly, a plurality of animation patterns. Such smart home devices may include a processing system configured to cause the light to illuminate using the plurality of colors and the plurality of animation patterns in response to a plurality of states of the smart home device.

Apparatus and method for ventilating a building structure, such as a residence. In some embodiments, a ventilation system includes a damper assembly which extends through an interior substrate (e.g., an interior wall) of the structure and an exhaust assembly which extends through an exterior substrate (e.g., an exterior wall of the structure and which is in communication with the damper assembly via a control circuit. The interior wall separates a conditioned space and an unconditioned space. The exhaust assembly is initially activated to vent exhaust air from the unconditioned space while a door of the damper assembly remains closed. The door is subsequently opened responsive to a measured environmental parameter, such as a differential pressure between the conditioned and unconditioned spaces, to generate a combined airflow that passes from the conditioned space to the unconditioned space and then to the exterior of the structure.

Examples herein describe systems and methods for dynamic building ventilation control. A control system can include a controller that receives information from the indoor and outdoor sensor packages. The control system can compare indoor and outdoor air quality using information from the indoor and outdoor sensor packages. The controller can also determine a current operational state of a heating, ventilation, and air conditioning (HVAC) system, such as heating, cooling, and fan status. Based on the air quality comparison and current operational state, the controller can open a first damper and closing a second damper to change ventilation of a building.

A dynamic misting control system can supply water to a condenser coil in varying degrees. The control system can include a controller, flow regulator (e.g., pump or separate), and mist generator (e.g., spray nozzles or otherwise). The controller can read outdoor humidity and temperature and vary power to the pump accordingly. The controller can also compare temperatures of the condenser coil to the outdoor humidity and temperature in adjusting the voltage. This can include calculating a voltage based on a first temperature of a coolant supply line and a second temperature in a return line and comparing those temperatures to the outside temperature and humidity.
