1 . A method for controlling at least one tintable window, the method comprising:
receiving sensor readings from one or more sensors associated with a facility;
determining a forecast of a weather condition at a geographic location corresponding to the at least one tintable window at a future time;
determining a tint state of the at least one tintable window of the facility based at least in part on the forecast of the weather condition; and
providing instructions to transition the at least one tintable window to the tint state determined.
2 . The method of claim 1 , wherein determining the forecast of the weather condition comprises providing the sensor readings to at least one machine learning model.
3 . The method of claim 2 , wherein the at least one machine learning model comprises a plurality of neural networks, and wherein the forecast of the weather condition is based at least in part on a combination of outputs of the plurality of neural networks.
4 . The method of claim 3 , wherein the forecast of the weather condition corresponds to a majority output of the plurality of neural networks.
5 . The method of claim 2 , wherein providing the sensor readings to the at least one machine learning model comprises selecting an input feature set relevant to the facility at the future time.
6 . The method of claim 5 , wherein the input feature set is used to initialize the machine learning model.
7 . The method of claim 2 , wherein the at least one machine learning model comprises a long short-term memory (LSTM) network and/or a dense neural network (DNN).
8 . The method of claim 1 , wherein the at least one tintable window comprises two or more tintable windows associated with a zone of the facility.
9 . The method of claim 1 , wherein the one or more sensors comprise one or more photosensors and/or one or more infrared sensors.
10 . The method of claim 1 , wherein the one or more sensors reside on a multi-sensor device.
11 . A system for controlling at least one tintable window, the system comprising:
one or more processors configured to:
receive sensor readings from one or more sensors associated with a facility,
determine a forecast of a weather condition at a geographic location corresponding to the at least one tintable window at a future time,
determine a tint state of the at least one tintable window of the facility based at least in part on the forecast of the weather condition, and
provide instructions to transition the at least one tintable window to the tint state determined; and
a controller in communication with the one or more processors and with the at least one tintable window, wherein the controller is configured to apply commands to transition the at least one tintable window to the tint state determined.
12 . The system of claim 11 , wherein determining the forecast of the weather condition comprises providing the sensor readings to at least one machine learning model.
13 . The system of claim 12 , wherein the at least one machine learning model comprises a plurality of neural networks, and wherein the forecast of the weather condition is based at least in part on a combination of outputs of the plurality of neural networks.
