  • Patent number: 11360121
    Abstract: A sensor for measuring current flow includes a power generation circuit, a current measurement circuit and a microcontroller. The power generation circuit includes a current transformer that harvests energy from a load applied to the conductor and uses the harvested energy to power the current measurement circuit and microcontroller. The current measurement circuit includes a Hall effect sensor that outputs a voltage signal in response to detecting a magnetic flux generated by the flow of current through the conductor. The microcontroller calculates a current measurement based on the voltage signal received from the current measurement system. The Hall effect sensor is able to generate the voltage signal used to measure current flow at the same time that the current transformer harvests energy from the current flowing through the conductor. A fault detection system is able to alert a user to problems with the current transformer and/or the Hall effect sensor.

    Abstract: A method for zone-based control of devices within a building management system (BMS) includes receiving a request to control a zone in a building. The method includes identifying a plurality of available zones in the building. The method includes receiving a selection to control a first zone from the plurality of available zones. In response to the selection, the method includes generating a password to restrict control of at least one device in the first zone. The method includes transmitting the password to the user device. The method includes receiving, via the input interface of the zone device different from the user device, the password. The method includes authorizing, responsive to receipt of the password via the input interface of the zone device, control of the at least one device in the first zone.
