Oscar Wong / Getty Most people who are serious about saving energy have considered investing in energy efficient appliances, switching to LED lightbulbs, and installing a programmable thermostat. If you’re ready to take your efforts to the next level, you many want to consider home energy monitor. These devices, usually about the size of a large mobile phone, are tucked inside your home’s electrical panel and are attached to the electrical main. They communicate data via wifi to show you how much energy your home is using overall, or in some cases, which devices in your house are hogging the most energy. This data allows you to figure out what you can do to improve and reduce usage (for example, maybe it’s time to upgrade that 15-year-old dryer). Home energy monitors connect to a mobile or web-based app so you can see what’s happening in real time—or even double-check if you shut off a certain appliance when you’re away from home. If you have a solar home, you can see how much energy your panels are generating and compare your energy production with usage. Although installation generally is simple, most manufacturers clearly state it’s not a DIY project because you must attach the device to your home’s electrical panel, which contains live wires that represent a shock hazard. Ahead, our top picks for home energy monitors: The Rundown Best Overall: Sense Energy Monitor at Amazon Jump to Review Best Budget: Emporia Energy Smart Home Energy Monitor at Amazon Jump to Review Best for Solar: Efergy Engage Hub Kit at Amazon Jump to Review Best Smart Plug: Kasa Smart Plug Ultra Mini EP10P2 at Amazon Jump to Review Best Overall: Sense Energy Monitor 4.8 Sense View On Amazon View On Sense.com Voice Control: Phillips Hue, Amazon Alexa, Google Assistant | Power Usage: Less than 5 watts | Solar Ready: Yes | Warranty: 1 year Life With a Sense Home Energy Monitor, the First Month The base model of this popular brand is our top pick for its ease of use and full-featured capabilities. It tracks usage trends in real time by day, week, month, and utility billing cycle so you can figure out your patterns and make adjustments to how you use energy. You also can set energy goals by device or whole home, by day, or in dollars or watts. Over time, the device learns your home’s appliances based on their off/on cycles (typically, it learns 12 the first month, and 25 to 30 after a year of use). You even can add individual sensors to big users such as HVAC systems or pool pumps to keep a closer eye. The app, which our tester found intuitive and easy to use, allows you to see what’s on when you’re not at home or send alerts in case you left the dryer on or the garage door open. The system can be used with smart plugs from TP-Link/Kasa and Wemo. For time-of-use plans, you can input your local rate zones for more accurate billing information. "I was struck by the immediate utility of using Sense's Power Meter display to simply keep track of consumption and identify how much specific devices were using. A quick flick of the Christmas tree lights on and off, for example, revealed that I'm a really bad Treehugger who absolutely should finish up our transition to all LED lighting soon." ~ Sami Grover, Treehugger Writer Best Budget: Emporia Energy Smart Home Energy Monitor Walmart View On Amazon Final Verdict Voice Control: No | Power Usage: Less than 3 watts | Solar Ready: Yes | Warranty: 1 year If you’re looking for a real-time monitor that’s budget-priced, this device has plenty of features at a reasonable cost.

What to Look for in Home Energy Monitors Real-Time Monitoring This allows you to see how much energy you’re using as you’re using it. Appliance Recognition Appliances have different ways of using energy, so this feature allows you to see which appliances hog the most. However, the feature isn’t 100% foolproof and tends to be somewhat hit and miss. For example, some appliances that use electricity in a similar way (such a heating device like a toaster or curling iron) are more difficult to differentiate from each other. Real-time Cost Tracking Some monitors show the cost of energy consumption as you use it, so you can figure out the effects of turning devices on and off on your bill. Solar Ready This allows you to monitor your solar power production and/or usage. Frequently Asked Questions How does a home energy monitor help the environment? These monitors help you identify energy-hogging appliances or bad habits (such as leaving electronics which consume standby power plugged in when not in use) so you can take steps to reduce your usage. Using less energy conserves natural resources and reduces the need to burn fuels such as coal and oil that can contribute to air and water pollution. Do home energy monitors require a professional electrician to install? Although some monitors include DIY instructions, all manufacturers (including the ones that offer DIY tips!) recommend hiring a licensed electrician for installation. That’s because the device must be attached to the live wires feeding into your electrical panel, which represents a serious shock hazard. Do home energy monitors waste energy? Not at all. They typically use from .001 to 5 watts, so it’s not a major contributor to your home’s overall energy consumption. Why Trust Treehugger?
