Abstract: Methods, systems, and apparatus, including computer programs encoded on computer storage media, for adjusting an indoor humidity at a property. One of the methods includes determining an estimated outdoor temperature in an area around a property; determining, using the estimated outdoor temperature, a target indoor humidity for the property; accessing data about the property; predicting, using the data about the property, whether an indoor humidity of the property will likely change within a threshold time period; determining, using the target indoor humidity and the prediction whether the indoor humidity of the property will likely change within the threshold time period, whether to adjust the indoor humidity of the property; and in response to determining to adjust the indoor humidity of the property, controlling, using the target indoor humidity, humidity equipment at the property to cause an indoor humidity at the property to move toward the target indoor humidity.

Abstract: Methods, systems, and apparatus, including computer programs encoded on computer-storage media, for monitoring and operations of a wireless HVAC system. In some implementations, a method includes determining that a thermostat associated with the property is presently unavailable to send or receive a wireless communication; obtaining temperature data collected by one or more sensors located at the property; identifying one or more models for temperature monitoring at the property; determining an operation to be performed by an HVAC system based on the temperature data and the one or more models; and providing data indicating the operation to the HVAC system.
