A touchless actuation system for a toilet includes a touchless sensor, a motor assembly, and a processing circuit. The touchless sensor is located within a closed reservoir of the toilet. The processing circuit is configured to receive a signal from the touchless sensor and to detect an object within a detection region based on the signal. The detection region is external to the closed reservoir. The processing circuit is configured to facilitate flushing of the toilet through interaction with the motor assembly when the object is detected.

The technology disclosed relates to selecting among devices room to interact with. It also relates operating a smart phone with reduced power consumption. It further relates to gesturally interacting with devices that lack gestural responsiveness. The technology disclosed also relates to distinguishing control gestures from proximate non-control gestures in a pervasive three dimensional (3D) sensory space. The technology disclosed further relates to selecting among virtual interaction modalities to interact with.

A controller of a building automation system, and a method thereof, comprising a communication component and a processor. The communication component communicates with one or more other controllers of multiple automation level devices. The automation level devices are associated with an automation level network of the building automation system. The automation level devices include the controller and the other controller(s). The processor designates a particular controller of the automation level devices as a global data server. The global data server provides synchronized images of a predefined set of objects across all controllers of the automation level network.

A building energy system includes HVAC equipment, green energy generation, a battery, and a predictive controller. The HVAC equipment provide heating or cooling for a building. The green energy generation collect green energy from a green energy source. The battery stores electric energy including at least a portion of the green energy provided by the green energy generation and grid energy purchased from an energy grid and discharges the stored electric energy for use in powering the HVAC equipment. The predictive controller generates a constraint that defines a total energy consumption of the HVAC equipment at each time step of an optimization period as a summation of multiple source-specific energy components and optimizes the predictive cost function subject to the constraint to determine values for each of the source-specific energy components at each time step of the optimization period.

A system for controlling heating, ventilation, or air conditioning (HVAC) equipment of a building includes one or more processing circuits configured to generate simulated building data using a simulation model of the building, pre-train a reinforcement learning (RL) model using the simulated building data, operate the HVAC equipment of the building using the RL model, and retrain the RL model using actual building data generated responsive to operating the HVAC equipment using the RL model.

A non-transitory computer-readable storage medium for a heating, ventilation, and/or air conditioning (HVAC) system includes instructions that, when executed by a processor, cause the processor to receive an input indicative of a user location, perform a verification that the user location is within a determined distance from the HVAC system, and control access to system settings of the HVAC system based on the verification.

Optically controllable windows and an associated window control system provide a building security platform. A window controller or other processing device can monitor for window breakage, cameras associated with windows can monitor for intruders, and transparent displays can provide alerts regarding detected activity within a building. A window control system can detect deviations from expected I/V characteristics of an optically controllable window during normal operation of the window (tint transitions, steady state conditions, etc.) and/or during application of a security-related perturbing event, and provide alerts upon their occurrence.

Occupancy data over time is received for each of several spaces within a building from occupancy sensors that are disposed within each of the spaces. An occupancy value is determined for each of at least some of the several spaces based on the received occupancy data, each occupancy value representative of a percent of time that the respective space was occupied over an identified period of time. The space that had a highest occupancy value over the identified period of time is identified. A utilization value is determined for each of the spaces, wherein the utilization value is representative of a ratio of the occupancy value of the respective space and the highest occupancy value. An operation of the building is changed based at least in part on the utilization value of at least one of the plurality of spaces.

Methods and systems for monitoring the performance of a building management system by analyzing log files of various modules of the building management system. A user request is received at a first one of the plurality of modules of the building management system, which initiates a sequence of messages processed by two or more modules. Each of the sequence of messages include a common tag value that corresponds to the user request. Each of the plurality of modules that process one of the sequence of messages logs the corresponding message including the common tag value in a corresponding log entry. The log entries are analyzed to identify resource utilization of at least some of the plurality of modules.

This relates to systems and processes for using a virtual assistant to control electronic devices. In one example process, a user can speak an input in natural language form to a user device to control one or more electronic devices. The user device can transmit the user speech to a server to be converted into a textual representation. The server can identify the one or more electronic devices and appropriate commands to be performed by the one or more electronic devices based on the textual representation. The identified one or more devices and commands to be performed can be transmitted back to the user device, which can forward the commands to the appropriate one or more electronic devices for execution. In response to receiving the commands, the one or more electronic devices can perform the commands and transmit their current states to the user device.
