NightDraw questions
How does NightDraw estimate electricity use?
Create rooms and add energy items with quantity and usage settings, such as hours per day and days per month. Enter your electric rate to estimate costs from your home model.
Does NightDraw connect to my utility or smart meter?
No. Its figures are estimates based on the information you enter, not readings from your utility account or a connected smart meter.
Can I sync my home energy model?
Yes, if you enable iCloud. Otherwise, your information stays locally on the device. TCQ Consulting LLC does not operate a server for your home model.
