It’s not summer yet but the West Cost is already bracing for its first heat wave of the year, with other regions not far behind. I’m worried your smart thermostat may not be caught up on summer temperatures. Fortunately, the right changes to your settings can prep your home while ensuring you keep on saving money without your AC going off the rails.

Smart thermostats excel at this kind of response, from automated changes to easy app updates even if you aren’t home. These recommendations will have you set for the heat to come.

1. Set ‘at home’ heating to 68 Fahrenheit

Check your summer scheduling in your app settings (such as the Ecobee app or the Google Home or Apple Home app) and use your scheduling options to set the daytime temperature — when everyone will be home — to 76 to 78 degrees Fahrenheit. That’s enough to keep the house cool without overheating or wasting energy.

If you like the heat and can get a reliable breeze by opening windows, you may be able to bump settings up to 80 degrees or so to save more money. But when outdoor temperatures start soaring well above 80 degrees, close the windows so they don’t dilute your cool air.

Important note: Some US cities have cooling regulations that indicate thermostats can’t be set above a certain temperature. They usually do this to prevent landlords from risking the health of the elderly or pets in an effort to save money during the hottest days. Check your city to see if it has any of these laws in place.

2. Set ‘away/asleep’ heating at 82 to 85 degrees Fahrenheit

When everyone is out of the house for work or school, or asleep with a healthy dose of blankets, set your temperature trigger to between 82 and 85 Fahrenheit, depending on what feels the most comfortable. Lower temperatures are typically better when you’re sleeping, while the house can usually endure higher temperatures when everyone is away — although you should also think about what keeps your pets comfortable.

Of course, we know that for some, sleeping when you’re too hot is impossible. That’s why it’s also a good idea to remove some bedding for summer and crack open a window when temperatures get lower. Try to avoid setting up indoor rotating fans or similar solutions, as they’ll eat into your electricity bill.

3. Turn on your Eco mode

Most smart thermostats have an Eco mode or a recommended mode for saving as much money as possible. Ecobee even has an Eco Plus mode that adjusts cooling based on local electricity use in peak hours to save more energy. Enable these modes and apply them to your thermostat settings to see their suggestions. Nest thermostats, for example, have a green leaf icon that shows exactly when you’re starting to save to make things easier.

Usually, Eco modes are the best way to save on your bills without thinking about it and they tend to be reasonable. My Google Nest Thermostat Gen 4, for example, usually sets my “hold” eco mode to 82 degrees Fahrenheit throughout the day and can be adjusted from there. These modes combine well with learning modes that keep track of your manual preferences and home activity to automate savings suggestions over time.

4. Create a vacation mode

If your smart thermostat supports a vacation mode or alternate mode, set it up so that this alternate schedule is ready for summer trips. You may want it a little cooler in the day than your full away mode settings to help keep pets and plants comfortable, but maximize your savings by skipping any “at home” temperature bumps. If no one is at home and you’re confident your house can withstand anything, close the shades and turn the cooling off entirely.

Note that the Nest thermostat doesn’t have a full alternate scheduling option but you can choose the “Add event” option for a similar result when creating your vacation plans.

5. Move your satellite sensor to a common room

Newer smart thermostats often come with a satellite temperature sensor or let you buy one as an add-on (here’s a Nest version for $40). This allows the thermostat to make cooling decisions based on a different location beyond the often-central thermostat installation. That can be very useful if parts of your home stay too hot (living rooms with lots of electronics, kitchens with active ovens, etc.) while air near the thermostat cools down too quickly.

However, be careful with this method because it could cost you more money in the long run (which may be a small price to pay for your comfort). To save money, you can move the sensor to the coolest room, such as a bedroom at night with the windows open.
