Attached is a screenshot of a HOBOware Pro project file that depicts a long-term (17-month) study of outdoor temperature data vs residential energy consumption. The data were recorded at 10-minute intervals and then filtered - using the HOBOware daily filter feature - to get average daily outdoor temperatures versus average energy consumption on the main power panel.
HOBOware Pro also includes weekly and monthly filters as well.
