Real-World Context
Heating/cooling is 50% of US home energy use
The Department of Energy estimates that smart thermostats can reduce heating and cooling costs by 10–15% — that is $100–$200 annually for the average American household. The payback period is typically 1–2 years, after which you keep saving every year.

Why Smart Thermostats Save Money
- Geofencing knows when you leave — heating automatically turns down when everyone leaves home and pre-heats before you return
- Learning algorithms optimise schedules — the thermostat learns how long your home takes to heat and adjusts start times accordingly
- Room sensors prevent over-heating — additional sensors measure temperature where you actually spend time, not just at the thermostat
- Usage reports identify waste — monthly reports show exactly when you use energy and highlight opportunities to save more
