Electric Car? Energy hog.

In the tumultuous business of cutting-in and attending to a whale, there is much running backwards and forwards among the crew. Now hands are wanted here, and then again…

Sense convinced renters to switch to gas heat

Our renters were using a space heater in their trailer at night, instead of their propane heat. Neither we nor they realized exactly how much that was costing until we installed Sense…

Water heater savings with Sense

I found out our 20-year-old resistance electric water heater would run for an hour or 2 at 900 watts. I researched water heaters and found one that runs like a heat pump using about…

Sense identified bad furnace relay

We started seeing an increase in our power bills over the Summer months of 2017. It had increased by $150, then up $300 more, by the end of the Summer we had a $900 power bill…

Good to know.

With just two clamp-on current sensors, the Sense Home Energy Monitor takes current and voltage measurements over 1 million times every second. From this incredibly high-resolution data, it derives the electrical signatures of individual devices. In comparison, most “high resolution” smart meters only take measurements every couple of seconds…hardly real time! You can read more about how Sense works in this blog post.

Within the first week of installation, Sense should be able to find some common devices that cycle on and off frequently, like your refrigerator or microwave. Some devices will take longer to identify, until the algorithms have seen enough contextual data to reliably detect them.

There are devices that Sense won’t be able to recognize right away, but as more Sense Home Energy Monitors are installed across the US and Canada, our machine learning algorithms will have more data to generate models from, and the device detection capabilities will just keep growing!

Even before Sense discovers devices in your home, it’s easy to see how much energy they consume just by turning them on and off and watching the Power Meter in real time. Check this video to learn more. 

Once Sense completes the signal check process, it will start detecting devices in your home.  Sense is able to identify many electrical devices in typical homes, and we continue to expand our device detection abilities via crowdsourced data as more Sense monitors come online. However, it likely won’t detect everything. Low-wattage consumer electronics like computers, smart devices, and game consoles can be especially tough to track. As we get data from more and more homes, the performance and coverage of our device detection will improve. In the meantime, many of our users have had great success tracking these more challenging loads via our smart plug integration.

To ensure you have the best experience with Sense, the following compatibility specifications are recommended:

Your home has:

  • 2.4Ghz Wi-Fi network with consistent internet connection. Sense is not compatible with 5Ghz Wi-Fi signals.
  • Its own electrical meter and accessible electrical panel.

Your mobile device runs on iOS or Android and has Bluetooth and Wi-Fi connectivity.

Your electrical panel:

  • Is a split-phase 120/240V residential panel up to 200A.
  • Must have enough space to fit sensor clamps with HxWxD dimensions of 3.375″ x 2″ x .75″ (85.73 x 50.8 x 19.05mm), and an inside diameter of 1”. The Sense current sensors may not be able to fit around busbars. Our sensor cables are 46″ (116.84cm) long and our power cable is 36″ (91.44cm) long. 
  • Does not drop below 32°F (0°C) or exceed 122°F (50°C).
  • Is not exposed to water or areas with high condensation (Sense complies with ANSI/IEC 60529 Rated IPx0).

For more information on electrical panel compatibility, check out this support article.

Sense should only be installed by a licensed electrician. Installation itself is quick and easy, but it requires opening up your electrical panel and connecting current sensors to the service mains. These wires are live, even with your main breaker switched off, and are thus very dangerous. Only a licensed electrician is qualified to work in these conditions.

When speaking with your electrician, let them know that Sense is an energy monitor that installs in your electrical panel with two clamp-on current sensors around the mains, and a 240V breaker which Sense uses for its power supply and also to measure voltage on both legs. Unless you have a spare 240V breaker in your panel, your electrician will likely need to provide a new one.

You may also wish to share with your electrician this blog post and video to help them get a better idea for what’s required.

A set of installation instructions is also included in the package, and available online.

At Sense we take security very seriously and we do everything we can to ensure your data is secure. All communications between the Sense monitor, the Sense cloud servers, and Sense apps are encrypted with AES 128-bit encryption and TLS/SSL (HTTPS). Sense uses Amazon Web Services (AWS) for cloud servers and online storage. Personally identifiable information like email address and account information is stored in physically separate systems from any application data. Physical security is managed by Amazon and access to these production systems is limited to a very small group of Sense engineering team members.

Automated systems process the data collected from Sense monitors to detect devices, send notifications, generate report emails, and power the Sense apps. Sense never shares any of this data with 3rd parties without explicit user opt-in on a case-by-case basis (for example, when a utility wishes to provide discounts/services to their customers in exchange for sharing limited power data.) Sense support employees will on occasion need to access some of this data to troubleshoot issues, but again we will only access this data with explicit permission from you.

You can read our full privacy policy here. 

After your Sense monitor is installed and the signal check process is complete, Sense will start pulling in data to feed its device detection algorithms. The device detection process is not immediate; Sense needs to see many on/off event cycles of a device in order start building up a model for it. Most customers will start seeing detections within the first one to two weeks. The first devices identified are often common devices that cycle frequently and consume large amounts of power, like your refrigerator or washing machine. Less commonly used, smaller load, or complex signature devices like coffee makers, televisions, and electric vehicles tend to take longer to find.

Please note that due to variances across homes in terms of power quality and in the types of device present, total detection coverage of your entire home is unlikely. To better understand how you can help Sense learn about your home, please see this Help Center article.

Sense needs to see devices in their usual context with their regular usage pattern to be able to accurately identify them. That means that “training” Sense by turning devices on/off and labeling them is not an effective method to help Sense learn. You can learn more about the challenges of implementing a “learning” mode here.

While you cannot “train” Sense in such a way, we have introduced a variety of features that take advantage of user input to help improve device detection in your home and for the entire userbase. 

Remember, even without native detections, you can still take advantage of Sense insights. The Power Meter is a fantastic tool that provides a real-time view of your energy consumption. Try turning on and off your devices while watching in the Power Meter, to identify how much they consume. You can do the same for the “Always On” devices in your home, identifying how much they’re costing you every day.
