WattPet

Electricity prices change every half hour. Move your usage into the cheap green hours, spend less, and keep your WattPet thriving.

Struggling0 days

That peak usage stings a bit.

Adjust usage

In the demo, you move appliances by hand to see the effect. The real product would do this for you: it learns your patterns from your smart meter, tells you tomorrow's cheap hours, and with your permission automates the shifting through smart plugs, EV chargers and heat pumps. The pet reflects how your home is doing either way.

WattPet is a prototype by Lee Firman, built as a working demonstration of gamified energy behaviour change. Households, neighbours and streaks are simulated. A production version would connect to your smart meter via the P1 port and your supplier's live day-ahead tariff.
