A method for determining ambient temperature of a device in a building control system. The method includes obtaining a measurement of ambient temperature from a first temperature sensor of the device and obtaining a measurement of temperature of a processing circuit of the device. These temperature measurements along with a brightness level of a display of the device and a state of a relay of the device are provided as input to a neural network. The neural network is trained to recognize these inputs in order to more accurately determine the ambient temperature of the device. The reading from the first temperature sensor may otherwise be inaccurate due to heat generated by electronic components of the device.

Temperature sensor calibration using recurrent network

A method in a heating, ventilation, or air conditioning (HVAC) system includes retrieving a control input from a remote computing system via a cellular network responsive to determining that a connection to a local wireless network cannot be established and generating a control signal for HVAC equipment based on the control input or generating a control signal for HVAC equipment by executing a backup control algorithm responsive to determining that a connection to a local wireless network cannot be established.

Backup control for HVAC system with headless thermostat

A heating, ventilation, or air conditioning (HVAC) system includes a headless thermostat device and an adapter unit. The headless thermostat device includes one or more circuits configured to receive a control input from a user device via a local wireless network and generate a control signal for HVAC equipment based on the control input. The adapter unit includes one or more circuit configured to receive the control signal from the headless thermostat device via the local wireless network and provide the control signal to the HVAC equipment for operation of the HVAC equipment in accordance with the control input.

Systems and methods for smart multi-zone control are provided. The system can include a plurality of sensors, a plurality of dampers, and a controller. The plurality of sensors can be configured to sense temperatures of a plurality of zones. The plurality of dampers can be configured to control the temperatures of the plurality of zones. The controller can be configured to obtain a first array associated with the plurality of sensors. Each element in the first array can represent a difference between a measurement value of a respective sensor and a setpoint associated with the respective sensor. The controller can be configured to obtain a second array associated with the plurality of dampers. Each element in the second array can represent a damper position of a respective damper. The controller can be configured to determine values of entries of a matrix using the first array and the second array.
