  • Publication number: 20240345552
    Abstract: Current thermostat data including room temperature readings, thermostat control commands, and user input temperature set point changes is collected. The current thermostat data is sent from a thermostat to a cloud server that creates and continually updates a first server machine learning model trained using previous and the current thermostat data, a second thermostat machine learning model is created for sending control commands to the thermostat using the previous and the current thermostat data, and the second thermostat machine learning model is updated. The second thermostat machine learning model is updated by sending updated model parameters from the first server machine learning model to the second thermostat machine learning model. One or more new thermostat commands determined from the current thermostat data are received from the second thermostat machine learning model and the one or more new thermostat commands are executed.

  • Publication number: 20240191898
    Abstract: A smart thermostatic system is disclosed that applies one or more of a reinforcement and/or adaptive learning model for a new environment with the trained model from another environment so as to initiate status of a thermostatic device. In one example, the thermostatic system uses a pretrained machine learning model that is transferred from a first thermostatic system to a second thermostatic system in a similar sub-environment. Temperature data and other data collected by the thermostatic device is used to fine-tune and train the pretrained model to learn, predict, and better adjust the operation of the thermostatic system.
