Because half my electric bill is dependent upon hourly usage totals, calculated each hour between 3 PM and 8 PM. The highest hourly total in a billing period times $16 makes every kW of Demand important. It may well save me more than $300 a year to be able to monitor my on peak usage. If you understand how your billing is done and what affects the numbers, yes, it can be well worth it. I love my Sense. Otherwise, it just gives you numbers that are meaningless. If you have no idea what I'm talking about, then it probably is not worth $300 to you. I hope this helped.

We have a complete solar bundle that includes everything you need, or you can add solar later on with our solar upgrade kit for $50. Both of those are available right here on Amazon. How to determine: Incoming solar feed must connect directly to your main electrical panel, either through a breaker or a service-side tap. If solar is set up in a sub-panel, the incoming solar feed must be within 46 inches of the main panel. This will allow the current sensor cable to reach and connect to the Sense monitor in the main electrical panel. To have clean solar production readings, there should not be any other live circuits connected to the sub-panel. If you aren't sure if your setup will work, email [email protected]

Updated March 2021 - Cool Device with improved features
Original Review 4-4-2018 ( Several Updates below original review):
Cool device and very accurate at detecting overall energy usage but individual device detection is hit & miss at best. I have had it for 3 months and it helps me monitor my overall home electricity usage in real time. It does an ok job detecting some appliances but a poor job detecting others (more on that below).
-It is 99.5% accurate for what my utility company is measuring and billing me for, so it is very accurate
-Detects amperage and voltage on each 120V leg (hidden in the app menu, go to: Settings->,My Home ->, Sense Monitor), which is great when you need to see if one leg of your panel has more usage or voltage issues.
-Does data collection about once a second
– Can quickly identify resistance loads (space heater, toaster, etc) and induction motors (older furnaces, older pool pumps, exhaust fans) within a week or so if used regularly. Most of these items were identified correctly but dont always get detected between cycles
-Devices with single speed compressors take a little longer to identify but eventually get identified correctly (fridges, traditional AC unit, dehumidifier)
-Install is not for the average homeowner (but not much can be done about that from the Manufacturer’s prospective). Having a pro install the component will be around $100 but there is not very good documentation to give a pro for install. The manufacturer has no real documentation meant for professional electricians (no electrical diagrams or requirements), so a pro who is not familiar with the product may struggle to get it wired into the panel quickly without going to the support website or calling technical support.
-For those with a panel with no room to add a new 2 pole breaker, your electrician will have to make room by adding at least 2 tandem breakers (at an additional cost)
-Wifi antenna extension cable needs to be longer. Installing the sense inside a metal electrical panel is dooming the device to have a poor wifi signal and the short extension cable for the wifi antenna is not very long, which made it a challenge to find a way to get the antenna mounted outside my flush mounted panel
– Device discoveries are usually ‘guesses’ that require the user to verify it but many of the guesses were not accurate for me. The guesses have become more wild over time (ex. a 10 watt load had a 88% chance of being a clothes dryer even though my clothes dryer wasnt on at all).
-Device will use a decent amount of network bandwidth, especially when it is first started because it is ‘phoning home’ to help identify usage patterns. (for those who have metered internet, especially Satellite Internet or those who use cellular data as the only means for internet).
-Will not detect variable speed motors (new pool pumps, modern HVAC equipment, HE washing machines)
– Will not detect lights on dimmers
-Struggles to find computers (I have a high performance desktop PC that stays on 24/7 and it has not been found in 3 months despite using the same amount of energy. My home office equipment in particular uses about 160KWH/month (but I know that thanks to the Kill-A-Watt, not the Sense monitor).
Suggestions for the Manufacturer:
-Create a device similar to the Kill-A-Watt that pairs with the Sense monitor to quickly ‘train’ sense on some of the most common appliances like computers, toasters, etc. This would greatly speed up the device discovery process and eliminate the guesswork for the user. I would love to walk around the house in a matter of hours and train the Sense monitor to detect most of my most commonly used objects. This would eliminate the months long process of guesswork involved.
– Create a ‘training mode’ that essentially lets a homeowner turn things on one at a time to help quickly (and more accurately) identify the most commonly used appliances and lights. Information provided to the homeowner will be much more accurate after the device is trained.
– Partner with a wifi extender company or offer one that easily extend a home’s wifi to the sense device. Most electrical panels are located outside of the living space of the home (building exterior, garages, or basements). Most wifi equipment is not going to be close to these locations and I would imagine that it would be needed often. My device in the garage is on the fringe of my wifi (50% signal strength) but my house is only 2000sqft with the wifi centrally located in the house. If my house was any bigger, I doubt the sense device would be able to stay connected to my wifi reliably.
– Technical documentation in PDF format for electricians. The website is great but an electrician needs a set of technical instructions that can be printed out by the homeowner. Also define whether it is ok to connect to a breaker that is designed to accept 2 conductors per circuit (like the Square D breakers).
-Web interface from a computer is incomplete. The web interface for Sense does not have the power meter function available, forcing the user to use the phone app.
This is a great meter but I would not install it in a customer’s home to help break down their usage by category. It is very cool to see usage realtime and what it does when you turn things on and off. I also think this device would be fantastic for someone wanting to get an idea of their home’s peak load so a backup generator could be properly sized for a home. I do not think the appliance identification is ready for prime time because most of the ‘suggestions’ were wrong. My house is fairly high tech with modern appliances (variable speed pool pump & Mitsubishi variable speed HVAC system) and the Sense device has not been able to identify any of them because their power usage constantly varies.
I expected more accuracy of detected devices for a $300 product plus the $200 I had to pay an electrician to put this in. I have a very expensive device that tells me how much total electricity my house uses each day (my power company lets me see the same reports on their website).
So my original review still stands (read that first) but here is an addendum.
-Web interface now has live power usage, which is great to view in a web interface.
– They now let you setup your billing cycle so you can view your billing cycle usage each month (as of this review, this could only be viewed from the phone/tablet app).
– Usage alerts – I can setup alerts to inform me if monthly usage is trending above a certain threshold. Ex. my first 1000KWH is dirt cheap but everything after that is more expensive. I usually use less than 1000KWH except in the Summer. Sense will alert me if things are trending towards going over my 1000KWH limit that I setup. I usually will get alerts fairly early in the billing cycle to help make sure I try to reduce my usage. This has allowed me to reduce my electricity bill by staying under 1000KWH for 7 months of the year so far (a 1000KWH usage bill is only $65 total)
The Bad –
-Things have not gotten any more accurate. In fact, the only accurate appliances that get identified on their own are: AC condenser (16 year old single speed outdoor unit), refrigerator, portable dehumidifier & mini fridge. I do have a generic 500 watt resistance (heat) load that I eventually created because the app sees it whenever I run one of the two small burners on my stove or my radiator space heater in my master bedroom (on low).
-My pool pump runs daily from 8am-5pm but is variable speed (Pentair Intelliflo -consuming 200-250 watts per hour usually). In the 10 months I have owned the Sense unit, it has never identified the pool pump as anything (not even a guess).
-The same goes for my computer. I have tried to turn the computer off at night but the Sense unit hasnt even attempted to guess what this daily ~225watt load is.
-One other appliance that I was surprised that the Sense unit could not identify is our dishwasher. We run it about 3x a week on the same setting every time. It is an older dishwasher from 2007, so it would be nice to see how much energy each cycle uses.
-From time to time, I log into the app and see that it thinks that appliances are running when they arent. I ‘report’ the errors and the app just says ‘we will use the info to make things more accurate’.
The problem with group machine learning is that the data has to be accurate (to become useful information). I dont feel there are many homeowners out there that are willing or able to accurately confirm all their appliances as running (they are more apt to just confirm the app’s suggestion that an appliance is what it really is). Garbage data input equals garbage data output. For example: a group of non-observant homeowners using this device could confirm the Sense guess that an appliance is their clothes dryer when it really is their oven (because they both have similar electric resistance loads). The machine learning becomes flawed and could start to predict other homes the same way.
Again, this device is very accurate at detecting overall energy usage and does a great job keeping track of overall energy usage BUT do not expect it to accurately figure out everything in your home on a granular level (ex. Dishwasher, Clothes Dryer, Iron, Clothes washer, living room lights, Coffee Maker, Toaster, Oven, TV, Cable Box, Cable Modem, Computer, Garage Lights, Vacuum Cleaner, Air Purifier, Pool Pump, etc). If those are your expectations, then you will be pretty pleased with the product. It still has great features but know it’s limitations based on on my (and other’s) real-world experiences and I think you will be happy.
Update Sept. 22, 2019
Device is still unable to detect anything accurately in my home except the garage lights, garage door opener, and a 500 watt heating element load. It occasionally gets my pool cleaner pump (not my main pool pump) but it also says its on during the day when it is clearly not, so the usage statistics are not accurate (such as percentage of daily usage). No matter how many times I report the device as not on, it eventually gets detected as falsely on after a few days. It does see my mini fridge and regular fridge but confuses the two back and forth on a regular basis, so again usage statistics for each device is wrong. It sometimes is able to nail my AC condenser but not always, so again, usage statistics are inaccurate.
This is a very good overall usage meter as it is accurate within a half a percent of what my utility company says I use and when I use electricity, but I stand by my statement that the appliance learning is a crapshoot at best. I have had the device for 18 months and it is unable to ‘learn’ my home appliances, so i have a glorified live energy monitor, which is useful, however I would never trust the appliance usage statistics.
Update: March 5, 2021
Upgraded to a solid 4.25 stars!
I installed a 6 panel solar array (enphase system) in Spring 2020 and this Sense monitor is my go-to for live production statistics. Rarely a day goes by that I dont check my solar statistics using this app. The enphase enlighten portal is great but it only reports individual panel production and house power consumption in 15 minute increments. The sense monitor can tell me second by second my solar production vs. grid usage. Since I have a small array, I dont export much to the grid but I plan to install additional panels when I can afford it (the majority of the costs of phase 1 was the design with expansion in mind, equipment install, the electrical wiring and conduit that had to be installed in a tight attic, luckily phase 2 will not require any house wiring changes this time).
The Great new features I am using:
– Solar section of the app is great (it is my go-to page)
– I am also very happy with the Sense Labs portion of the app. The best part of sense labs is the electrical fault detection. It is constantly monitoring the power quality and lets you download a 30 day history of any voltage dips and spikes into a csv spreadsheet format. Why is that important? If you have a electrical feeder or floating neutral with an intermittent connection problem like I did (ours was a bad connection on one of the two 125v power feeders at the transformer). Having this information can help you provide information to your power company or electrician when they are trying to troubleshoot an intermittent problem like flickering lights. Labs also looks at motor stalls, which is great, especially for AC units. It may alert you to the fact that a capacitor on an induction compressor or blower motor is failing or has failed (this will cause winding damage and eventual failure if left untreated).
– Integration with thermostats and smart wifi plugs & switches. Now the devices it can identify are more accurate and you can see usage stats on the individual TP-Link wifi switches.
– Expansion port is not just for solar anymore. It can now be configured a few different ways, which is helpful for those with 400 amp service panels (two 200 amp panels in the home). I still wish there was a way to do 400 amp service and still monitor solar (this is not a problem for me, but some larger houses with solar may not be able to take full advantage of a sense monitor unless they roll out a version with multiple sensor ports or they find a way to parallel two monitors on the same account).
The rest – Most of what I said in my past reviews still stand but accuracy is decently better. I do think it is worth it now for most homeowners to get one. It helps shed light on our usage and it provides some monitoring and alerts for things like power quality and motor stalls that a homeowner may not be aware of until it gets a lot worse. It is also very obvious that they are constantly improving features and accuracy. They have a great forum that their staff looks at (including asking for feature improvements).
Even though this product is not perfect, you can tell that they are continuing to innovate and add new useful features (and so far the price point has not changed since I purchased it).09/21/2022Verified Purchase
Works as advertised
I’ve been thinking about getting the Sense Monitor for some time. I have seen it advertised online and was curious how it worked and what it could do for me. My setup at home is I have solar and bought an electric car (Leaf) a few months ago. I was interested in seeing how much electricity my Leaf was pulling from a 110v plug. I figured in was in the 1kw to 1.5kw range. I always felt my I had my home running as efficient as I could with newer appliances, LED lights, and power settings set on different devices. My goal with the Sense was not to save money, but more to see how it worked, what my different appliances were using, especially an old refrigerator in the garage. With Solar meeting my current energy needs, I’m not looking for any particular ROI on this investment. My thoughts so far on the Sense are:
1. Installation- ok, the constant you must use an electrician had me a little nervous about trying to install myself. While I have a basic understanding of electricity and how my house is set up, I had never worked in the breaker panel before, other than flipping a breaker. I watched as many videos on installation as I could and understood that the Sense needs to hook up to a 240v. I didn’t have a free 240v breaker and have no room to add a new one, outside of adding a subpanel. I decided to add the Sense to an existing 240v breaker that is labeled for master bedroom lights etc. While this may not be up to code in my area, not really sure honestly, the Sense uses such little electricity, 4w, and .05amp, I crossed my fingers that this would not be a disaster. I’m sure an electrician would lecture me about not doing this but hopefully, all will be ok. I put the Sense on the lowest rated 240v breaker, per Sense recommendation. To install I had to turn off the main breaker, solar, and solar inverter. After getting the sense hooked up I turned everything back on but didn’t hear the beep you are supposed to hear when Sense is hooked up correctly. I turned the main breaker off/on again and thankfully I heard the success beep from the Sense. The only problem I have is finding space in the breaker box for the sense. My breaker box is a bit crowded so I need to spend some time putting it in a better place, right now I have it kind of just laying on the bottom. ***If you have no clue about electrical setups and what is in your breaker panel, get an electrician.***
2. Application/web page- after successfully installing the Sense I set up the app on my iPhone and checked out the Sense webpage to view my data. The Sense will first run through a check before it starts listening for your devices. Sense page said that it can take up to 24 hours to complete the test. I think mine was finished within 6 hours. Two days in my Sense is still listening for devices. At the 48 hour time frame Sense did identify my ‘always on’ power usage and created a category for those. Now it will take time to start identifying individual devices and appliances. It is interesting to see how much total wattage/kw I am using at any time. You can see spiked when different appliances turn on/off. A few surprises based on this information, my new Sony OLED 55 inch tv does not use as much electricity as I would expect. I think it is in the 80-100 watt range. My furnace that is 3 years old and 2 stage runs about 500 watts, really not bad all considering. My Leaf, when plugged into 110v standard outlet pulls about 1500 watts. As I am writing this review, Sense just emailed me that it found its first device, my fridge. Since I have two I was curious how I would tell which one it is. Based on watts used per day it looks to be my newer, more efficient kitchen fridge. The fridge in the garage is old and would pull more watts than what Sense is saying this fridge is pulling. I’m on my way with device/appliance detection, will be interesting to see how Sense does. I did give Sense the ability to monitor my home network to help identify electronic devices in my home, and I have a lot as I’m an IT professional and geek. On another note, I have some Wemo and Phillips Hue lights and Sense integrates with those to easily identify them and monitor their usage. You can also turn your lights on/off through the Sense app.
3. Value- Sense is not cheap, but I’m sure some of the price is to help pay for continued monitoring, data storage, and data management. As a technology geek, I don’t mind spending a few $’s to try something out, it is just a hobby for me. If I was not a geek, it would be hard to justify the price. Sense says they are focusing on helping owners get more value from the device, and I think that is a good thing for them to do as to get higher adoption beyond early adopters, they need to show value for the price. With Solar, I’m not going to save anything as I can cover my electrical needs with my installation. The new variable which may change that is my Leaf. The Sense will let me monitor and become more knowledgeable on my home efficiency to help make sure I’m keeping all my electricity needs covered by solar.
If you are interested in Sense and needs someone to install the device, consider the full cost of the device and installation. The price may not be worth the potential return on investment, at this point in time. If you like technology and want to check it out etc, I find Sense a very cool device and I’m satisfied with how it is working and what it is providing to me.05/14/2022Verified Purchase
