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 variable refrigerant flow system for a building includes a plurality of indoor units, a first outdoor unit, an outdoor meter, and a variable refrigerant flow management system. The plurality of indoor units configured to generate activation requests. The first outdoor unit is configured to receive the activation requests and, in response to the activation requests, provide a refrigerant to the plurality of indoor units. The outdoor meter is configured to provide an outdoor unit electricity consumption measurement. The variable refrigerant flow management system is configured to receive the outdoor unit electricity consumption measurement and activation data indicating the activation requests and apportion an outdoor share of the outdoor electricity consumption measurement to each of the plurality of indoor units based on the activation data.

Abstract: A building management system is communicably connected to an energy blockchain network to reduce energy costs of a building. The system includes an energy load balancer to distribute energy from a plurality of energy suppliers to power a load in the building, a processor, and memory storing instructions that causes the processor to: monitor energy pricing data from each of the energy suppliers; calculate a balanced load payload corresponding to an energy demand forecast for the building according to the energy pricing data from the energy suppliers; generate a smart contract corresponding to the balanced load payload in blocks of the energy blockchain network to procure energy from corresponding ones of the energy suppliers; and generate load balancing instructions for the energy load balancer based on the smart contract. The energy load balancer switches between the corresponding ones of the energy suppliers according to the load balancing instructions.

Abstract: A building management system includes one or more processing circuits. The one or more processing circuits are configured to receive, from a physical building device of a building, environmental inputs and environmental outputs of the physical building device; generate a building device digital twin for the physical building device based on the received environmental inputs and the received environmental outputs; generate a predicted future performance of the physical building device based on the building device digital twin; and generate a recommendation based on the predicted future performance of the physical building device, the recommendation indicating one or more changes to implement on the physical building device. The building device digital twin is a model for predicting the behavior of the physical building device ore changes to implement on the physical building device.
