Smart home gadgets and technology can help make homes more energy efficient than ever before. From thermostats and lightbulbs to plugs and sprinklers, there is almost no aspect of the home that can't be integrated with a smart home system. But which devices can help you save the most energy?

What is a smart home system?

A smart home system is built around home automation. Smart devices have the capability of connecting to a smart home hub like Amazon Alexa or Google Assistant through your Wi-Fi network, Bluetooth, or Z-wave technology. You can then control and monitor these devices through a smartphone app, usually on iOS or Android devices, or through voice commands with a smart speaker.

One of the biggest uses of smart home functionality is in the smart home security system. Smart locks, video doorbells, wireless security cameras, and even garage doors can be managed through voice control or a mobile app.

Energy efficiency is another important factor in the choice of smart home devices. Through the use of a smart sprinkler, smart plug, smart lighting, or smart thermostat like the Google Nest or ecobee SmartThermostat, homeowners can see major improvements in their energy and water consumption.

And that is just the tip of the iceberg. More and more devices are being integrated into smart home setups. Even appliances like stoves, dishwashers, and refrigerators are now connected to the internet.

What are the best smart home devices for saving energy?

As mentioned, one of the biggest advantages of smart home devices is in saving energy. One thing to consider before adding new devices or appliances is getting a home energy audit for an accurate picture of where your home is less energy-efficient. Once you know that, here are some of the best smart home devices to help you become more energy efficient.

Sense produces smart home energy monitors that allow users to track, in real-time, their energy usage throughout the home and even through specific appliances. The Sense home energy monitors are some of the most popular on the market today. Learn why in our review below.

Sense overview

Sense stepped into the home energy monitor industry just a few years ago. The Boston-area company began using machine learning in order to provide real-time looks at electrical usage. This also came in the wake of a discovery that always-on devices accounted for nearly 23% of all home electricity usage.

Sense developed its tech with a team from some of the biggest names in voice recognition. The team consisted of engineers from Amazon, Vlingo, Phillips, SpeechWorks, ScanSoft, and Nuance.

What came of that was the Sense home energy monitor. This Wi-Fi-enabled sensor has the capability of displaying real-time energy use data right to users' smart phones thanks to a small box that attached to the home's electrical box.

Sense offers sophisticated energy monitoring

Compared to others in the industry, Sense is top of the line. Its diverse range of features, easy-to-use smart phone application, and even a solar energy option for improved savings, is the reason for the higher price tag.

Despite the relatively high price, consumers have rated it quite well. Utility companies have verified that it is 99.5% accurate and it can even track usage of individual appliances for improved accuracy and tracking.

It has shown that it records 1 million data points per second, which is a rate that is not only larger but faster than most other competitors. Combined with other energy-efficient products like smart thermostats and smart lights, the Sense energy monitor could help you reduce your energy consumption considerably. For those looking to get a better sense about their power usage, Sense may just be the best the market has to offer.

Types of Sense home energy monitors

Sense works by connecting a monitor to your home's breaker panel. It then takes the voltage and current measurements of your electricity consumption. It does this over 1 million times every second to produce high-resolution data. The monitor then transmits the data through a Wi-Fi antenna to your app or desktop.

Furthermore, Sense is capable of individual device detection. This allows you to get a sense of how much energy your home uses, and which appliances and electrical devices use the most energy when running.

There are two Sense home energy monitors: the standard Sense unit and the Sense Solar. The latter is meant to provide the services to those who run off of solar power, providing greater clarification and understanding of solar energy usage.

Sense Energy Monitor


The Sense energy monitor provides real-time, 24/7 data that is accessible through iOS, Android, and desktop apps. That means being able to check energy usage patterns whenever it suits you. Even better, schedules and alerts can be set at the user's discretion to create a truly customize data system.

Why buy: The Sense home energy monitor allows for optimal energy tracking convenience. Users can get live updates on their power consumption from their smartphones whenever and wherever they like.


How it works

The Sense home energy monitor works simply enough. It attaches to your home's circuit breaker, measuring energy usage right down to individual appliances and devices for a better understanding of where your home's electrical usage is. Sense recommends that you have a licensed electrician do the installation.

There are also customer safety monitors that can be set with audible notifications. Keep track of critical devices like well pumps, sump pumps, HVAC systems, water heaters, or flat irons without having to constantly monitor them yourself. Most importantly, the components have been ETL/Intertek certified. That certification ensures that it is safe for operation within an electrical panel.

The Sense features compatibility with many smart home devices. Pairing up the Sense with Google Assistant, Amazon Alexa, Phillips Hue, IFTTT, smart thermostats, and smart plugs can help you optimize your home's energy efficiency.

Sense Solar Energy Monitor


Like the Sense, the Sense Solar can track usage data in real-time. It can also track your appliances and devices on an individual basis to give you a more comprehensive window into your home's energy consumption.

Why buy: The Sense Solar can detect the exact amount of energy that the solar panels on your home are generating 24/7. This feature quickly gives you a better idea of which appliances are drawing power (and how much) at any given time as well as the effectiveness of your solar panels.


How it works

The Sense Solar home energy monitor is much the same as the original version, though this one tracks solar energy usage. It connects to your home's breaker panel like the Sense, just with an additional wire to connect to the solar inverter in your home's main electrical box.

The Sense Solar uses the same simple interface for its smartphone function that the regular Sense does. Users can chart energy usage over time, even creating profiles of monthly, weekly, or daily usage, whatever works best for the user.

It is recommended that only electricians handle the installation process.

The Sense app

Perhaps the biggest selling point for both Sense and Sense Solar is the mobile app. The Sense app is used to connect to their smart home energy monitors and provides the ability to monitor volts and current one million times per second.

The real-time, 24/7 data is available in a number of interfaces that allows for customized profiles. Users can set monitoring reports that display overall usage as well as individualized device performance.

With a large, easy to identify interface, users are able to generate reports that fit their usage needs. Moreover, they can see real-time data to monitor devices as they run.

If that weren't enough, users can also set goals, view trends, and even set audible alerts whenever energy levels are too high. The Sense app lets you take control of your home's energy usage and electricity bill.

Sense pros and cons


Both the Sense and Sense Solar have their own distinct advantages and disadvantages. Here is a breakdown for both versions.

Sense pros

For starters, the Sense app is super user-friendly. Even the most technologically-challenged can pick up the app and navigate its interface with little to no trouble.

Moreover, the app shows a ton of historical data. If you want to look at specific trends going back to installation date, you can call those up easily. Daily, weekly, and monthly reports are available to provide a better understanding of data usage over time so you can identify patterns and problem spots.

Finally, it provides individual device tracking. If you want to get truly granular and see which devices take the most energy to run, that is easily available through the app.

Sense cons

At $299.99, the cost isn't cheap. Furthermore, professional installation is highly recommended. That is an additional cost on top of the already steep price for the unit itself. Those installation fees take an already costly unit up a notch.

There is also the issue that it does not have cost calculations. While it can track energy usage in real-time, it doesn't tell you what that translates to in terms of actual money. Knowing what your energy is costing you will take a little extra sleuthing.

Sense Solar pros

The Sense Solar energy monitor is one of the best at tracking solar production in real-time. Some similar solar devices only offer updates in 15 minute increments whereas the Sense Solar can track up to the second.

Moreover, it tracks electrical production and consumption as well, so you know if your appliances are drawing more energy than the solar panels are putting out. Not to mention the user-friendly app that makes it possible to create various profiles for tracking and consuming data.

Sense Solar cons

Even more expensive than the standard Sense at $349.99, the Sense Solar monitor is definitely an investment. This particular home energy monitor is designed to help homeowners get the most out of their own solar panels. If you just want to identify ways to reduce energy usage, there are definitely cheaper options.

The other negative is that it has trouble finding always-on appliances. That's not to say it can't find them, it just takes some time and patience. It also may detect the same device multiple times, creating confusion.


Both the Sense and Sense Solar energy monitors deliver real-time data on electrical consumption that can be customized however the user wants. Aside from needing a professional installation, users can access and customize data easily through the app, creating profiles displaying information that can help you save money on your electric bill.

Though it is one of the most expensive options on the market, there are few that can deliver real-time data customization and app convenience the way the Sense does. With a 99.5% accuracy in readings, it is hard to top the convenience and accuracy that Sense provides.

Sunrun Overview

Founded in 2007, Sunrun's mission is to create a world run by solar energy. Since 2007, Sunrun has expanded at an impressive rate, now offering services in over 20 states as well as Puerto Rico and Washington D.C.

Sunrun designs solar panel layouts custom to a roof's shape via satellite imagery, giving homeowners more control over the appearance and efficiency of their systems. The company's integrated home solar battery storage service, Brightbox, sets it apart from the many other providers that have yet to deploy storage options that bring a number of key benefits to solar customers.

Sunrun also provides a wide variety of solar financing options for its customers. Catering to a large client base has allowed for Sunrun's massive growth, but it's also presented challenges that have soured the company's reputation online. The BBB gives Sunrun a rating of a B+, which is lower than the average solar provider.

Sunrun Solar Services and Installation

Sunrun is a comprehensive solar installer, providing design and installation of custom solar solutions complete with backup battery storage, home energy monitoring and energy control during outages. These tools can help homeowners manage, store and monitor their home's energy use for additional savings on their electric bills.

The types of panels and inverters Sunrun offers come from brand names like SolarEdge, LONGi and Costco. They are ideal for the quick and easy installations that Sunrun prides itself on. An average customer could expect the installation process to look like this:

  • Receive a free quote by providing preliminary information such as your address, monthly energy costs and credit score.
  • If interested after receiving the quote, a Sunrun sales rep will provide a detailed proposal including your custom system design, appearance and estimated energy savings over the course of the system's lifetime. The proposal should include any local and state solar incentives, so be sure to make note that any are included.
  • Once you've decided on the custom system that fits your needs, you will need to complete paperwork and obtain permits and approvals. Sunrun will handle the permits and approvals from your presiding city or county, but you should expect this process to take a few weeks.
  • During the permitting process, Sunrun will also check for net metering programs through your utility company and will enroll you if eligible.
  • Once all permits and approvals are gathered, Sunrun will install your system. With Sunrun's resources, this will likely be the easiest part of the entire process.
  • Finally, you'll need to pass inspection and turn on the system. Once the system is installed, both the city and your electric company will most likely require inspections. Sunrun will handle the logistics of both. Once these pass, a customer will be able to turn the system on.

Solar Panel Warranty

All Sunrun installations, whether leases or purchases, are covered by the Sunrun Guarantee. This 10-year comprehensive warranty includes free equipment replacement and system repairs, covers all parts and labor costs and guarantees that roof penetrations are watertight.

Sunrun advertises free maintenance, repairs and insurance on its products, but it should be noted that those services are only available to customers leasing panels through Sunrun. Any customers who have purchased panels from Sunrun will be held to the product warranty of the panels they purchase (typically between 12-25 years). As such, all warranty claims will be handled through the panel manufacturer rather than Sunrun.

Sunrun Costs and Financing

The cost of a solar system from a particular provider is difficult to estimate, as pricing can vary widely depending on your state, your roof and your home's energy needs. As Sunrun has been an industry leader for some time, most other solar providers actually offer installations at a slightly lower cost to give them a competitive edge. This is just another reason we encourage our readers to get quotes from competing solar companies.

Much of Sunrun's expansion can also be credited to its utilization of solar leases, which allow homeowners to rent solar equipment from Sunrun at a monthly cost. Though leasing panels provides immediate energy savings with a low upfront cost, purchasing panels provides the greatest value long-term. Keep in mind that leases will not be eligible for the solar tax credit.

Solar Financing Options

Sunrun offers four different solar plans for its customers.

  1. Monthly lease: This option requires the least money down but also provides the least overall value. Sunrun retains ownership of the panels and you make monthly payments to purchase the energy they generate. The monthly payments are guaranteed to be less than what your utility payment would be, but the savings are not as great as they would be if you purchased the panels.
  2. Full lease: In a full lease, the customer pays Sunrun an upfront fee to rent the panels for around 25 years (the term of the lease can vary). Sunrun retains ownership of the solar equipment. This saves a customer more money than a monthly lease, but it's still significantly less than if a customer purchased panels.
  3. Monthly loan: Customers can receive a solar loan from a third party to fund the purchase of solar equipment. These loans require monthly payments and typically have a payback period of between five and 10 years. In a monthly loan, a customer still owns the system outright, which adds to their property value, allows them to claim the solar tax credit and provides greater long-term energy savings than a lease. However, they will pay interest on the loan, making the system more expensive.
  4. Full purchase: A full purchase is the most recommended method of investing in solar energy. When customers purchase panels, they buy the system designed by Sunrun outright. Immediately, the solar panels add property value and the homeowner is eligible for the solar tax credit. Over time, homeowners will see a larger return on investment when paying in cash.

Sunrun Solar Reviews

Sunrun's size is both its biggest strength and its biggest weakness, and most customer reviews reflect just that. Positive Sunrun solar reviews praise the company's speed and ease of installation, yet a high employee turnover rate, communication troubles and growing pains have plagued a number of customers who feel their needs were not met.

Positive Sunrun Reviews

The size and resources of Sunrun make its business model reliant on high volumes of installed solar panels. Positive reviews usually reflect a quick and easy installation with immediate energy savings and little to no maintenance or further customer support needed. Most frequently, these positive reviews come from customers who opted for a solar lease rather than ownership.

Here are a couple of examples:

"I originally had my Solar installed by another company that was eventually purchased by Sunrun. The service with Sunrun has been far better than the service with the previous company."
— Brian Schopf via Trustpilot

"We have had our Sunrun system in place for over a year now. No problems at all. They were very courteous and responsive during the installation process."
— Peter W via BBB

Negative Sunrun Reviews

Most of Sunrun's negative reviews stem from a lack of attention to a customer's needs. Sunrun is one of the nation's largest solar providers, which presents challenges for customers troubleshooting issues with their system's performance.

Solar panel issues can be difficult to troubleshoot, and the size of Sunrun's client base can make the company's customer service department more difficult to get in touch with than a smaller solar provider.

This Sunrun review reflects the overall sentiment from dissatisfied customers:

"Worst company ever for follow-up once you have a problem… I have been waiting for a new inverter [for] seven months. No one bothers to tell you what they are going to do, or what they have done once they finally get to your house for a repair. No written report to update you. I have lost money this year because my system is either not running or is underperforming."
— Linda T via BBB

Final Thoughts on Sunrun Solar

Sunrun's mission, size and breadth of services make it one of the most well-known solar providers in the country today. However, its B+ BBB rating and poor reputation for customer service may make some buyers wary. An average customer experience with Sunrun will depend greatly on the quality of the sales representative assigned to your area, and many homeowners have run into bad experiences.

Sunrun Pros Sunrun Cons
Expansive service area Expensive labor
Backup battery services Frequent customer service issues
Free maintenance on leases
Flexible financing and lease options

Sunrun is a good and practical choice for customers looking to quickly and simply save money on their energy bills through a solar lease. However, for homeowners looking for attentive customer service both before and after installation, we advise you to shop around.

Frequently Asked Questions

Is Sunrun a legit company?

Sunrun is a legitimate solar installer leading the industry in quantity of installs and breadth of products offered. Hundreds of thousands of homes across the country have installed solar power with Sunrun. Though Sunrun is legitimate, there is a concerning amount of bad reviews regarding Sunrun's customer experience. Often, unconcerned sales staff can make customers feel their business was not taken seriously.

Is Sunrun solar a good deal?

As is the case with most solar providers, getting a good deal is dependent on many factors. Sunrun is certainly capable of providing customers with a solar energy system that saves them money, but a better deal might be found by a different solar provider, especially if you are looking to purchase panels rather than lease from Sunrun.

Is Sunrun owned by Tesla?

Sunrun is not owned by Tesla. In fact, Sunrun is one of Tesla's biggest rival companies in the solar industry. Unlike Sunrun, Tesla solar offerings focus more on products and less on installation services, so the companies are distinctly different.

Which is better, SunPower or Sunrun?

Which company is better will depend on what the customer is looking for. If you're looking for customer service, a high BBB rating and to purchase high-quality panels, we'd likely recommend SunPower over Sunrun. If you're a customer looking for a quick and easy solar panel lease to save a small but guaranteed rate on your energy bill each month, Sunrun may be the better choice.

Additional Nest Products

The Nest and Nest Learning thermostats are not stand-alone products. There are accessories that can be integrated with these models to provide a better heating and cooling experience than they may offer on their own.

Nest Temperature Sensor

No matter what type of HVAC system that you have, it sometimes doesn't evenly heat or cool each room in your home. So, what do you do when there are rooms in your home that are a little warmer or colder than the others?

The Nest Temperature Sensor is meant to help with that. The Nest Temperature Sensor goes into individual rooms in the home and works in tandem with the Nest thermostat. By detecting the temperature in those rooms, your smart thermostat can better distribute heat or cold air, accordingly, providing a more even air distribution. That means no pockets where the temperature is noticeably different than the rest of the home. This also helps prevent your system from working extra hard, and using extra energy, to make up for those differences.

Nest Hub for Voice Control

You can pair the Google Nest thermostat with Google Assistant through the Nest Hub or Nest Mini, or most any smart speaker. You can also connect your Nest thermostat to Amazon Alexa to implement voice control into your smart thermostat experience. This lets you adjust the temperature without having to go to the thermostat yourself.

Additionally, Nest offers smart home products like the Nest Cams, motion sensors, video doorbells, and more that you can integrate into your smart home system.

Nest Thermostat Energy Rebates

The Google Nest line of thermostats are meant to provide energy savings and efficiency to users. In addition to making HVAC systems more efficient, they make temperature control far more convenient and easier.

Additionally, there are potential energy rebates to be had by using the Google Nest thermostat line.

Smart thermostats are often times compatible with smart phones and tablets, allowing the user to program features remotely.

What to Look for When Buying a Smart Thermostat

There are a few things worth considering when buying a smart thermostat. Energy savings are the most important; after all, it is one of the primary reasons for buying a smart thermostat in the first place.

Moreover, convenience and number of options are an important consideration. That means ease of smart phone app use, how quickly you can program the thermostat, and the individual room functionality that it provides.

How Much Energy Can a Smart Thermostat Save?

On average, the Google Nest thermostat and its various incarnations can expect to save anywhere from 10-15% on annual energy usage. For most average-sized homes, that equates to about $130-$145 saved on energy bills each year.

This number can vary based on a couple of factors. The size of home is important as larger homes will have greater energy needs. Secondly, it depends on the condition of your HVAC systems. Old and outdated systems may still be compatible with the Nest, but may have certain limitations on their efficiency to begin with.

What Other Smart Home Products Help Save Energy?

Smart thermostats are a great way to cut down on the energy needed to heat and cool the home. But what else can help save energy usage? Smart products typically involve some sort of scheduling system to ensure that they run only when needed.

Smart plugs can help you manage your home's appliances to optimize their energy consumption, and smart lighting can ensure that you are conserving energy when no one is home.

For those who frequently care for their gardens, a smart sprinkler system can be beneficial. Save on water, set watering schedules, and reduce the amount of water needed to keep the yard healthy. Similar to a smart thermostat, a smart sprinkler system can save 10-20% on water usage in a given year depending on the size of the property.
