TariffTuner

TariffTuner helps households cut electricity bills by turning confusing time-of-use tariffs into simple, actionable schedules. It connects to your utility rate plan (manual entry or supported integrations) and learns your typical usage patterns from smart meter exports or home energy monitor data. Then it generates a “do this now” plan: when to run laundry, charge an EV, pre-heat/cool the home, or avoid peak pricing. It also sends alerts when rates spike or when you’re about to hit a demand charge threshold (where applicable). This is not a magic savings button—if you can’t shift load, savings will be limited—but for homes with flexible appliances, EVs, or heat pumps, it can deliver real, measurable reductions. The app focuses on clarity: projected monthly bill impact, confidence ranges, and a simple weekly checklist instead of charts nobody reads.
