What moves the number

Your old habits. If you already set back the temperature at night and when you leave, a smart thermostat has less to fix.
Climate and system. Bigger heating and cooling loads leave more to save.
Whether you leave the features on. Learning schedules and away modes only help if you don’t override them.

Is it worth it?

At roughly $50 a year, a thermostat pays for itself over a few years, sooner if your utility offers a rebate. Check your utility before you buy. See smart thermostats on Amazon

Renters who can’t swap the thermostat can automate a window AC instead with a SwitchBot hub . If you’re tracking household bills more broadly, see Monarch vs Copilot .

What my agent can do with it

A thermostat is a good agent device because the stakes are low and the data is useful. An agent could check the forecast and your calendar, pre-heat before you get home from a trip, and send a monthly note on runtime. Keep it to setpoints, not system settings.
