Product Description

Sense Flex Hero
Sense,energy monitor

Add One of Four Capabilities with Included Flex Sensors

Circuit Monitoring

Split Service Icon

Standby Generators Icon

Solar Monitoring Icon

Dedicated circuit monitoring

Track up to two 120V or 240V circuits. It’s the best way to track devices like your HVAC system, EV charger or variable speed pumps.

400A split-service

Whole-home monitoring for homes with split-service 400A electrical systems, more common in newer, larger homes.

Standby generators

If your power is interrupted, Sense can tell you when your back-up generator takes over and how much energy the home is using.

Solar monitoring

Sense Flex includes a second set of sensors, like Sense Solar, which can also be used to monitor solar production in the very same way.

Monitor Your Home's Energy Use From Anywhere With The Sense App

Save Energy and Money

Understanding how much energy your home is using, when and where, empowers you to find savings. Sense gives you the tools to break it down and take action.

See What’s On

Get a view into your home you can’t get anywhere else. See when the garage door opened, the television turned on, or when the dryer finished its cycle. Sense can monitor many devices, but we can’t ensure it will track everything. Certain devices may not be detected due to their unique signature, like low-wattage LED light bulbs or variable speed motors in certain heat and pool pumps.

Avoid Disaster

Sure, it’s convenient to know when certain devices turn on and off, but it may just save your house, too. Heavy rains? See if your sump pump is running, or running too much! Think you forgot to turn off the oven? Set an alert to inform you if it’s been on for over an hour.

Track Time-of-Use Rates

As Sense tracks your home’s energy, it begins to recognize most appliances and other devices that use more than 60 watts. Typically the Sense monitor detects 12 devices in the first month after it’s installed and 25-30 devices after 12 months.

Machine Learning Device Detection

As Sense tracks your home’s energy, it begins to recognize most appliances and other devices that use more than 60 watts. Typically, the Sense monitor detects 12 devices in the first month after it’s installed and 25-30 devices after 12 months.

Useful Integrations

Sense integrates with select IoT devices to give you more control, with your voice or inside the Sense app. See what’s possible when you link Sense with Hue, Amazon Alexa, Google Assistant, and smart plugs from TP-Link/Kasa and Wemo.

Rigorously Tested For Safety

Any device inside your electrical panel should be designed and certified to meet the highest safety standards. In addition to extensive in-house testing, the Sense monitor has been tested to UL and IEC standards for safety and certified by ETL/Intertek as safe to install in your electrical panel.

Customers are mixed about the performance of the home lighting accessory. Some mention that it works better than expected, the app works surprisingly well, and it offers a convenient and effective solution for keeping power costs in check. However, others say that it does not work well with the ones it does detect, it stopped working after 4 months, and that it's not actually very useful.

Customers are dissatisfied with the value of the home lighting accessory. They mention it's a waste of money, not worth the money, and a terrible product. The gimmick is flawed and not as smart as it claims. Customers also say the cost was not justified and they're returning it before the 30 day time expires.

Customers are dissatisfied with the connectivity of the home lighting accessory.

Amazing second-by-second live power monitor
5 Stars
Amazing second-by-second live power monitor
The Sense monitor is an amazing device. Having used a live power monitor for 10+ years (the Current Cost EnvIR), Sense takes this to the next level. Highly accurate - to the point where it can "see" the microwave door opening because the light comes on, even with the device not running.Because it ties into the electrical panel using 2 breaker slots, it monitors L1 and L2 voltage and can detect and report power spikes, floating neutral and motor stall conditions using some of the Sense Labs features. It uses AI to learn and associate devices in your home to their detected electrical "signatures", and has learned the majority of frequently-used devices in mu house in the first 30 days.I also added several compatible "smart plugs" that support energy monitoring to monitor specific devices even more accurately and to control them from within the app.It can be configured to warn you if a sump pump hasn't run recently (if expected to run), or whether you may have left the oven on. So it can add to home safety in addition to energy monitoring and identifying power saving opportunities.Highly recommended!
