Tools and techniques are described to modify a defined space state depending on number of users in the space and/or preferences of users in the space. In some embodiments, users entering or leaving a space are noticed by network systems. A controller then modifies resources in the space to account for the greater or lesser load. In other cases, the network system notices that a specific user has entered a building. This user may have preferences stored in the system which the building control system then responds to by changing state of a device that controls physical state within the space.

Tools and techniques are described to create a controller wiring board. A user, using a user interface associated with a controller, can determine which devices will be attached to a controller. The features of the devices may be already known by the controller. The controller can change wiring terminal types depending on the requirements of the devices wired to the controllers. In some embodiments, a device is wired to a module associated with the controller. The controller can signal to the module to modify its wiring terminal to match the needs of the device to be wired to that location.

The present disclosure relates to a method for determining phase connections of grid components in a power grid, the method comprising assessing a relative similarity of time series of measured voltage data of the grid components by clustering the time series of measured voltage data of the grid components; grouping the grid components into a plurality of clusters based on the assessing a relative similarity; and assessing a phase connection of the grid components in each cluster of the plurality of clusters. The present disclosure also relates to a respective device and computer program.

A circuit and method for realizing a combined connection of neutral wires or live wires using phase information of the neutral wires and the live wires are provided. The circuit includes a phase detection module. The phase detection module is connected to a power grid via the live wire VL and the neutral wire VN. The phase detection module includes a high-voltage phase detector, a first inverter and a second inverter. The output of the high-voltage phase detector is sequentially connected to the first inverter and the second inverter. The method includes: arranging nodes on the live wire VL and the neutral wire VN of the power grid, respectively; defining the nodes by determining a phase relationship that a high-voltage signal first appears on the live wire VL or the neutral wire VN; and connecting systems to be connected in parallel to the power grid through the nodes.

A system comprises: electronic apparatuses; a management apparatus comprising a connection positional relation database for managing connection positional relations of the ports of the electronic apparatus; and an information communication terminal. The management apparatus acquires disconnection target port information from the information communication terminal and thereby reads information related to the disconnection target port from the connection positional relation database to transmit to the electronic apparatus. The electronic apparatus transmits a visible light signal to outside based on the information related to the disconnection target port. The information communication terminal displays the information related to the disconnection target port based on the visible light signal.

A connector connection verification system includes a cable connector and a networking device. The networking device includes a port system defining a port and including a networking device connector, and at least one cable connector sensor device that is located adjacent the port. The cable connector sensor device(s) detects that the cable connector is inserted in the port defined by the port system while the cable connector does not mate with the networking device connector included in the port system and, in response, transmits an incorrect connection signal that indicates that the cable connector is incorrectly connected to the port system. A management interface provided on the networking device may receive the incorrect connection signal from the cable connector sensor device(s), and provide information that describes the cable connector and that indicates that the cable connector is incorrectly connected to the port system for display on a display device.
