Building system with a time correlated reliability data stream

A method of a building system comprising:

• collecting, by one or more processing circuits, building device data of a building device, the building device data comprising a plurality of data samples of a data point of the building device;
• collecting, by the one or more processing circuits, network traffic level data of a building network of a building;
• determining, by the one or more processing circuits, whether the building device data is reliable based on the network traffic level data;
• generating, by the one or more processing circuits, a time correlated data stream for the data point based on a determination whether the building device data is reliable based on the network traffic level data, the time correlated data stream comprising values of the plurality of data samples of the data point;
• and
• generating, by the one or more processing circuits, a time correlated reliability data stream for a reliability data point, the time correlated reliability data stream comprising a plurality of reliability values time correlated to corresponding values of the plurality of data samples of the data point and indicating reliability of the values of the plurality of data samples of the data point.

A building device comprising:

• one or more memory devices configured to store instructions;
• and
• one or more processors configured to execute the instructions causing the one or more processors to:
• collect building device data of the building device, the building device data comprising a plurality of data samples of a data point of the building device;
• collect network traffic level data of a building network of a building;
• generate a time correlated data stream for the data point, the time correlated data stream comprising values of the plurality of data samples of the data point;
• determine whether the building device data is reliable based on the network traffic level data;
• generate a time correlated reliability data stream for the data point based on a determination whether the building device data is reliable based on the network traffic level data, the time correlated reliability data stream comprising a plurality of reliability values time correlated to corresponding values of the plurality of data samples of the data point and indicating reliability of the values of the plurality of data samples of the data point.
