The climate + economic case

Small box. Fleet-scale impact.

Conservative per-home savings, multiplied across a deployment. Drag the dials — every number is computed live from verified SA tariffs and the official grid emission factor.

Assumptions

Homes deployed 100.0k

SA has ~17m households — even 0.6% is a fleet.

Electricity reduction 8%

Real-time feedback drives 5–15% (evidenced).

Water reduction 12%

Leak detection + behaviour: 10–15%.
