Smart home devices do more than just make your life easier — they can also help you trim cost from your monthly energy bills. By automating things from your lighting to your thermostat, you can optimize your home’s energy use and eliminate waste without lifting a finger.
If you’re ready to stop guessing where your energy dollars are going and start managing your home with precision, this guide will get you started learning where smart energy devices can save you energy and money.

How do smart home devices save you money?
Smart home devices can save you energy and money. These devices let you monitor, control, and automate household tasks in a way that can reduce your energy use to save you money. Smart heating and cooling, lighting, large appliances, water heaters, and more let you run your home in a more energy-efficient way.
Smart devices that monitor and schedule energy intensive tasks can help you save by letting you use less energy and avoid peak rates on time-of-use plans.
Control your lighting
Lighting accounts for about 5% of the average annual energy consumption (and 11% of electricity use)for a single family home in the United States. Light bulbs left on when no one is in the room translate to unnecessary costs and wasted energy.
Smart light bulbs or smart switches that automatically dim or turn off lights when not needed can help solve that problem.
Smart light bulbs
Smart bulbs are arguably the easiest devices you can incorporate into your home for energy savings. All you need to do is replace your old bulbs with these energy saving products.
Smart lights come with a higher price tag than standard LED light bulbs. If your goal is to save money, their automation and scheduling capabilities need to make up the difference. If you find yourself forgetting to turn lights off when you leave the house, smart lights may cut down on that waste since you’ll be able to turn lights off from anywhere using a phone app. Another approach may be occupancy or vacancy motion sensors, which will turn lights off when they don’t detech motion.
Smart light bulbs also offer greater control and convenience by offering features such as:
- Remote control using a smartphone app
- Voice control via a smart speaker
- Customize lighting for activities like reading, watching movies, or hosting friends
- Follow a time-based schedule to turn light on and off
Smart switches
Smart switches come with many of the same benefits of smart lights, but can be extended to other devices, like fans. Some smart switches come with motion detection capabilities, lighting up a room, hallway, or path only when someone is passing by.
Save on cooling and heating
According to the US Department of Energy, up to 55% of the energy used in homes goes to heating and cooling needs. Therefore, using energy-saving heating and cooling systems is crucial for achieving smart home energy savings.
A variety of devices can help you use less energy and keep the temperature more consistent.
Smart thermostats
Smart thermostats are a popular, highly convenient energy saver
You can program a smart thermostat to meet the ideal temperature for comfort and savings on a specific schedule and adjust that schedule automatically with geofencing. Remote control allows you to switch your heating and cooling on or off, or adjust temperature settings at any time and from anywhere.
Smart thermostats can also save money by reminding you when system maintenance is necessary, such as when it's time to change your air filter. Some can even detect issues with your HVAC system and ducts and warn you of potential problems.
Smart ceiling fans
To achieve greater smart home energy efficiency with heating and cooling, you can use a smart ceiling fan to support the thermostat. Ceiling fans make rooms feel four degrees warmer or colder, reducing your reliance on HVAC systems and saving energy.
As with other smart home energy-saving devices, you can control a smart ceiling fan using your phone, tablet, or other connected device.
Smart blinds and smart window coverings
You can control smart window treatments using your phone or voice commands to open and close blinds on a set schedule, or based on temperature, even when they are hard to reach. Blinds and curtains can reduce the amount of heat that enters or leaves your home via your windows.
You can also program smart window coverings to respond to the environment automatically. They can open in the winter when the sun is out to let in the warmth from the sun, and close up in the summer as soon as your AC turns on.

Kill vampire power
Some devices, referred to as energy vampires, continue to use power even when they're turned off and in standby. It is estimated vampire energy accounts for 13.7% of a US home's annual energy cost.
A few devices can kill energy vampires automatically, so you're not stuck unplugging them when you're not using them.
Smart plugs
Smart plugs serve as a bridge between the outlet and the device you want to power.
You can use them to turn devices on or off from your phone, or to put them on a schedule, or program them to turn off automatically after the last person leaves the house.
One of the biggest advantages of smart plugs is that they are arguably the cheapest energy-saving devices available, and can turn almost any appliance into a smart device.
Some of the other benefits of smart plugs include:
- Identify appliances that consume a lot of energy so you can make informed decisions about your next purchase
- Make your house seem lively and occupied, even when you are away from home, to increase home security
Smart outlets
If you don’t like the idea of a two-part connection, opt for smart outlets instead. Just like smart plugs, smart outlets turn connected devices into smart appliances by controlling their power supply remotely or on a schedule.
The main drawback to smart outlets is you have to replace the power outlets in your home. However, the end result can be less obtrusive, as most smart outlets look nearly identical to a regular outlet.
Conserve water
Along with electricity, a lot of water goes to waste in homes. According to the Environmental Protection Agency (EPA), the average household's leaks can account for nearly 10,000 gallons of wasted water every year, and 10% of homes have leaks that waste 90 gallons or more per day. Finding and fixing those leaks can save homeowners about 10% on their water bill.
Smart leak detectors
Smart leak detectors sense water problems and send alerts when they detect an issue, allowing you to address the issue swiftly. Using smart leak detectors can be very valuable for saving money and stopping a leak before it’s a bigger, more expensive problem.
Smart leak detectors can have additional features such as:
- Monitoring water flow in pipes in real time
- Providing recommendations on how to conserve water
- Shut off the flow of water into the home after detecting a leak
Smart sprinkler controllers
Smart sprinklers can save money on energy by enabling efficient water use, allowing you to easily schedule when they turn on and for how long.
When it rains, a smart sprinkler system can skip a watering session automatically, ensuring that watering is done according to environmental conditions.
Smart appliances
Another category of smart home energy saving product and water conservation method you should consider are smart appliances. Dishwashers and washing machines use electricity and water to clean clothes and utensils, and smart appliances are an ideal solution as they are energy-efficient and use less water.
More importantly, some smart appliances can even be programmed to connect with the grid and operate when energy is cheaper to gain additional savings.
Unlocking the full value of energy savings
Rising utility costs are arguably the primary reason most people look for smart home energy savings.
Adding smart home devices is a great first step towards an energy-efficient home. You can further reduce your electricity costs by turning to solar for your energy needs.
