1. Automate Your Home’s Temperature

When it comes to saving money with smart home devices, a smart thermostat should be your first purchase. Heating and cooling amount for a significant portion of the average monthly home energy bill, and accounted for as much a 16% of the entire residential energy sector  in 2021 according to the Energy Information Administration.

Smart thermostats make it easy to regulate the temperature of your home within an energy-efficient range based on your internal environment, as well as the temperature outside. Some of the hottest days can also be some of the most energy-demanding, and smart thermostats can help by adjusting your home’s temperature in slow, energy-conscious ways that slowly build a comfortable environment over time.

One of the most expensive ways you can change the temperature of your home is by cranking up or down the temperature as soon as you step in the door. These devices help curb that impulse, and are designed to save you money.

Amazon Smart Thermostat

The Director of Smart Home at Amazon, Marja Koopmans, spoke with SPY about the best ways to save energy using smart home devices for this piece. She noted that “the best energy-saving smart home devices are the ones customers can program and then forget about – devices that run in the background and know when to power down or reduce usage, without customers having to do anything.” The Amazon Smart Thermostat is designed to do just that.

According to Koopmans, it’s an “ENERGY STAR-certified thermostat that works with Alexa to give customers a simple way to keep their home comfortable and energy-efficient. Customers can control the Amazon Smart Thermostat using a compatible Alexa-enabled device, or even have Alexa do the programming for them with Hunches. When Alexa has a hunch that you’re away from home or have gone to bed for the night, the temperature will adjust to help you save energy.”

“The device also comes with energy-saving temperature thresholds recommended while setting up a schedule, to help you choose the best temperatures straight out of the box. You can also monitor and better understand your energy usage while using your Amazon Smart Thermostat and other smart home devices with the Energy Dashboard available in the Alexa app.”


Google Nest Thermostat

Google’s Nest Thermostat is another excellent device for saving money on your energy bill, and also comes with an ENERGY STAR certification backed by a hand full of energy-efficient features. This includes turning itself down when you’re away and finding and suggesting tweaks you can make to your temperature schedule to help you save money within the app. It also comes with HVAC monitoring and automatic alerts if your system doesn’t seem right, or something needs fixing.

2. Set a Timer for Lights and Appliances

Ambient energy drain from unnecessary lights, as well as idle electronics and appliances make up a combined significant percentage of your monthly energy bill, as much as 46% according to a model cited by in April of 2013. Think about how many electronics you have plugged in throughout your home at any given time. Sure, some things are getting a much-needed charge, but other things are sitting there, in the background, almost literally draining money from your pocket. Thankfully, smart devices can help you eliminate this vampiric effect.

Both smart lights and smart plugs come with energy-saving features. Gone are the days when realizing you’d left the upstairs hall light on before your trip meant you were out of luck. Now, you can turn your lights on/off from your smartphone, and even program a timed schedule. Smart plugs allow you to do this with lights as well as any appliance or electronic in your home, so you can cut those energy vampires off at the source.

Koopmans also added that Routines enables Alexa users to “turn off their smart lights, plugs, switches and other devices when they go to bed. Customers can easily monitor and manage their smart home energy usage via the Alexa energy dashboard in the Alexa app.”



For outdoor security lights and systems, employing ones with a motion sensor is a great way to save energy, and deter predators and pests more effectively. Motion-activated security cameras are designed to turn on when they sense movement, rather than sitting idly on all the time capturing footage that isn’t useful or protective. Here are two great smart devices for home security that are energy-efficient.

These Ring smart security lights are compatible with the Echo 4th Generation smart speaker, Echo Show 10 and Ring Bridge, so you can connect this light with other Ring Smart Lights, Ring doorbells or security cameras.

3. Reduce Ambient Power Usage

As we mentioned in the previous point, ambient power usage quietly cranks up energy usage and energy bills for many U.S. households. Leaving your devices plugged in all the time is a great way to make sure they’re always charged, but there’s no use in paying for energy you don’t need and aren’t using. Devices like flat screen TVs, monitors, coffee makers and even speakers can leak energy from your supply quietly in the background.

Smart plugs and power strips can monitor how much energy your devices are using, and automatically turn off the power when they’re not in use. The two products below are what we recommend.

Wyze Plug

Wyze’s smart plugs also sync with an app and enable scheduling throughout the day, so you can turn devices on and off depending on when you need them. You can group various devices and lights together so they’re turned on and off at the same time, and even set a “Vacation Mode” to make it look like you’re in town.

It’s also currently discounted 41% on Amazon.
