Time of Use Rate Zones

Installation in Box

Two Sensors

Track Time-of-Use Rates

If you're on a Time-of-Use rate plan, you can input your rate zones for more accurate billing and historical costs. You can even set push notifications to alert you when entering peak zones.

Installation

Installing Sense is a straightforward process that generally takes a licensed electrician less than 30 minutes to complete. Two sensors clip around the service mains that connect your electrical panel to the grid.

Monitor Two Circuits Directly

In addition to Sense’s machine learning device detection and smart plug integrations, you can monitor up to two 120V or 240V circuits directly with dedicated circuit monitoring. Using optional locking Flex add-on sensors, it’s perfect for large loads and critical devices like your HVAC system, EV charger, or variable speed pool pump.

Monitor Compatibility and Specs

Where does Sense work? The Sense monitor will work in your home if it has a split-phase 120/240V or a 400A split-service residential panel with individual panels up to 200A. It is compatible only with electrical panels in the United States and Canada.
Installation Requirements Installation of the Sense monitor requires a 240V circuit breaker to measure voltage on each phase. The Sense monitor consumes less than 5W. Sense should always be installed by a licensed electrician.
Space Requirements You must have enough space to fit sensor clamps with HxWxD dimensions of 3.72″ x 2.3″ x .433″ (94.49 x 58.50 x 11mm), and an inside diameter of 1.565”. Sensor cables are 46″ (116.84cm) long and the power cable is 36″ (91.44cm) long. Cable extensions may be purchased separately.
Wireless Specifications 802.11 b/g/n 2.4 GHz WiFi – Bandwidth Use: ~300 MB/day
Environmental Ratings Relative Humidity: < 90%; IPX0 rating, no water ingress; Temperature: 32-154ºF (0-68ºC); Elevation: < 6562′ (2,000m)
Locking Sensors Newer monitors are equipped with locking sensors that fit most standard and main breaker meter combo panels. Please contact Sense customer support if you receive non-locking sensors and need locking sensors. After confirming panel configuration, Sense will send a complimentary set of locking sensors.
Flex Add-on Sensors Only one set of Flex add-on sensors can be installed with a Sense monitor. Flex add-on sensors use the port reserved for solar monitoring. You may need to punch out the cover to the port to access it.

Great overall energy monitor to learn big picture and help save
I have had a Sense for over 4 years now and I still enjoy it very much. I have used it to reduce overall energy consumption in my home by helping raise awareness of "Always On". More on Always On in a moment.My one warning - its not a "Buyer Beware", but more "Buyer be aware". Sense's ability to live up to its marketing hype with device detection is affected by many variables. Some homes have good results. Others don't. I've had reliable detections that work great for a while, and then stop working when the seasons change.Another thing to keep in mind. We tend to think of appliances in their whole. "The Fridge". "The Washer". Sense uses Machine learning algorithms to detect devices. Notice I said devices, not appliances. Your Fridge is actually a whole bunch of different parts that do different things at different times. Sense may detect your "Fridge" but it has actually only detected the compressor. It may not detect the defroster, or the ice maker. Or it may detect those things, but not necessarily as "Fridge". There are tools to allow you to merge detected devices. So if it finds "Fridge" and then it finds "Light" and you know that "Light" is actually the Fridge Light, you can merge them together so it all gets tracked together.This leads me to the next item. Sense doesn't always know what its detected. It knows it found something, and it can generally put a category to it (Motor, Heating Device, Light etc..) but the leg work on finding out which motor, or which light may be on you. Sometimes this is really easy. You turn on your bathroom vanity lights and see "Light" turn on in Sense, and you know and can then rename "Light" to "Bathroom Vanity". Other times, its harder to track down, especially when the device detected is a part of an appliance. This is where the active community forums comes in. Sense's Machine Learning is good, but at times, a human is better. Frequently people will post the graphic of the device that was detected, and other community members can chime in with suggestions. "I have a Garbage Disposal that has a waveform like that. Do you have a Garbage Disposal?"While I say a human eye is sometimes better, this is another item to mention. Training Sense is NOT something you can do. People always ask "can I train it". The short answer is no. Sense's ML system will do its work and find devices on its own. There is no training mode. Turning something on and off a bunch of times to try to "help" Sense see it is not always useful.Now, back to Always On. While my device detection has been so so, the Always On feature is what has really saved me the most money. After running Sense for about 48 hours, it will come up with an Always On number. This is basically the "low water" mark for electric usage in your home. At any given point in time, you are always using around xxx Watts. If you have an always on of 100w, using the average US rate of electric of 13.28c/kWh, that is $9.70/month or $116/year on your electric bill. While Sense cannot help you identify the Always On devices, just the awareness of the always on is enough to help you start making changes (if you want) to your home. Seeing my always on power of 600w (~$700/year) made me start looking for things that didn't turn off. I had a fan in my basement that ran 24/7 that I had never thought about. Now that fan is on a timer and only runs 12 hours a day.My TV stereo system which was always on is now on a power switch. Savings of 15w of Always On power. And the list can go on. Without too much effort, and more importantly, without impacting the comfort of the home, I have cut that always on number down to 300w.A last benefit of Always On. Once you learn your homes baseline, if that always on changes significantly in one direction or another, it can help to notify you that something is amiss. Always on goes down? Maybe a failed pool recirculating pump. Always On goes up a lot? Someone left the fan in the guest bedroom on. And so on.So all in all, I highly recommend a Sense. Whether it detects many of your home devices, or you just use it as a live instant power meter, it can bring savings and knowledge to your electric consumption in your home.
