Pick your utility and rate plan. We use it to learn when power is cheap, expensive, and most expensive — then cool your home around those windows.
Step 2 — your comfort, your rules
Set comfort & floor for each price window
For every pricing window, choose the warmest you'll tolerate (comfort) and the coolest we may pre-chill to (floor). The line riding over the ribbon is the setpoint plan we'll run.

How these numbers are built: runtime is sampled every 15 minutes from your thermostat; the “hold 79°F” comparison is a model estimate using cooling-degree-hours times a thermal coefficient k learned from your own logged runtime. Rates shown are the all-in price per kWh including the fuel rider and tax. Swap the placeholder rider/tax for the figures on your real bill in Settings for exact dollars.
