These days, our smartphones are practically glued to our palms. But what if you could use that screen time to save energy instead of passing hours doom scrolling on that social media app? Here are just a few of the sustainable actions you can take without putting down that trusty device.

1.Adjust the thermostat

You can use the connected app to adjust its settings if you have a smart thermostat. Manually raise or lower the temperature for comfort and energy savings, or input your daily schedule so the thermostat can automatically regulate your home's temperature.

2.Remember to change the filter

Tired of having to remember when it's time to replace your HVAC filter? There's an app for that.

Filtrete™'s app allows you to set reminders for one or multiple filters around your home, so you'll never forget again. You can also step it up a notch and opt for their Smart Air Filters, which include Bluetooth-connected sensors that can monitor air flow and usage of the filter instead of just time.

3.Turn off the lights

Left the downstairs lights on after you've already ascended the stairs to the bedroom? We've all been there. If you have smart bulbs and the connected app, however, you can correct your mistake from the cozy comfort of your bed.

You can turn these bulbs on and off, dim them and even change their color with just a few taps. Smart bulbs can also automatically adjust their settings based on a set schedule, which you can also program in the app.

4.Reduce the water temperature

Most water heaters are preset at 140°F, and the U.S. Department of Energy recommends lowering the temperature to 120°F. Lowering the temperature can help reduce the amount of money you spend on water heating. And this can be as simple as adjusting the temperature on your home's thermostat.

A retrofit smart controller lets you make existing devices smart without changing the wiring or updating to a newer model. This includes your water heater, but there are countless possibilities with this exciting new technology.

5.Turn off unused electronics

Smart plugs are an efficient solution for those home devices that simply plug into an outlet. Just insert a smart plug into the outlet, then the device into the plug, and you can turn your coffee maker, television and more on or off through the connected app. You can also create a set schedule for certain appliances and devices so they run on your preferred schedule.

Connected smart devices and smartphone apps bring efficiency to your fingertips. Just a tap or two, and you can make your home more comfortable and efficient — and save some money, too
