How appliance plans work

A contiguous load must use adjacent half-hours; a split load may use separate half-hours. Choose whether the maximum delay is measured by when a plan can start (start-by) or when it must finish (finish-by).

Every appliance is optimised independently. Suggested runs may overlap, and the result discloses those overlaps rather than silently moving either appliance.

Limitations

Optional energy examples are editable assumptions, not appliance specifications. Constant-power estimates do not model changing load, device efficiency, battery losses, circuits, fuse limits, or wider household demand. Standing charge is excluded. Published rates are not a bill, and published carbon intensity is not an emissions total.

Choose a region with the private region finder, or use best time for one contiguous run.
