Great Tool For Understanding Your Energy Consumption If Your Patient and Willing To Do A Bit of Simple Detective Work

Easy Install, excellent instructions, great customer support. I've had it installed for just under 2 weeks and it has found nine devices. Of those 9, I have been able to positively identify 5. The other 4 I am having fun playing detective trying to identify, as all but one are low frequency and low watts. The one thing I am anxiously waiting for is for Sense to identify a few of my big ticket items, like my main house ducted 3-ton heat pump, my Rec room pair of 1-ton ductless heat pumps, and my swimming pool. All of these have variable frequency drives with soft start motors that probably make it difficult to detect as they ramp up slowly and change over time. I have also noticed that the Sense daily kWh estimate is usually within 1 kWh of the number I get from my utility provider, which convinces me Sense is pretty accurate. It has also told me that I have a pretty high "always on" kWh number, relative to what Sense reports as an average.

Unexpected Results

I love technology but this has exceeded my expectations. It was very easy to install and in 15 minutes I knew exactly how many Watts my home was using. Now, I purchased this to understand my daily energy usage as I was upgrading my portable emergency generator but really didn't know where to begin in calculating every plug, refrigerator, freezer, light bulb in my home. This was perfect for knowing exactly what I needed, but the added benefit is that I found things in my home that are drawing more power than I realized, heated floors for example and I found Blubs in my home that were still using incandescent bulbs. After a month my energy use dropped by $2.10 per day per Kw... then the next month it dropped $2.76 per day per kw. That may not seem like a lot but that works out to $63 and $83 a month savings. I am only 2 months but absolutely love this. The app is great and is constantly listening to new signals. I was able to tell from work that one of my daughters left the sink water running and our well pump was drawing energy every 2 minutes to refill the tank. I am now excited to see my energy bill every month... to see the savings.

New Technology

This is fun and interesting new technology. It’s not perfect but you can help the system learn as it learns your home’s electrical loads. The system “listens” to your electricity flow and tries to recognize individual appliances based on their electrical signature. When it does, it gives you details on when, how often and how much electricity the appliance uses. There is also an active user group along with a responsive company to help work out issues. If you are technically minded and an early adopter Sense may be right for you.

Pretty awesome tech here

I believed in this but was really hesitant in getting it until I couldn’t find out why my energy bill was so high. I went plugging in this kWh reader I had but it was a slow process. Decided to order it and it’s exactly what I thought. The technology used to recognize the watts used is great. The fact that it can recognize the change as soon as it happens and reports it goes a long way in understanding the inefficient appliances in your home. Whether it’s bulbs or old appliances it’ll measure it as precisely as anything out there. Once installed this thing will have you running around the house unplugging things just to see what you save. It’s an adventure honestly and you learn a lot about your appliances. You’re old stove? Uses about 3k watts to charge to high. Once it gets to the temp is when it shutters between 3k w and 500w or so. It’s incredible what you learn from these things, it’ll give you a better idea of what to look for in efficient tech. Your iron, heater or anything that creates heat uses pretty much the most energy. You’re fridge idles at 380 watts or so but turns up to 3k watts. This thing is great. Totally recommend it to anyone with the desire to learn about there appliances. Can’t wait for the bubbles to form. Heard it uses machine learning which is cool.

I wish it had better integration with home automation systems

The following is my opinion based on my experiences. If I recall correctly, I saw this device on This Old House. I bought it because we are adding insulation to our home (all electric). I wanted to see the impact of the new insulation on electric use. This device filled the need. It also has some extra features that I've found useful. It detected our motion light. So I put a notification on the motion light so that I know when it comes on. I wish it had better integration with home automation systems. It does support IFTTT, but I want to keep my setup simply and inside my network if possible. Some of the competition has MQTT integration which would really meet my needs. If I did better research before buying, I would have probably bought something else.

Even better than expected.

I have a small apartment that is connected to my homes electricity and other utilities. I ran it out and I was having an issue with renters abusing electricity usage and running up the bill. I decided to make this purchase and my father actually attached it to them breaker box that is on the outside of the apartment he said it was very easy. I have found out that when they are conservative with the electricity they're only using 40 to $50 of electricity a month and when they are not conservative they are using a whole lot more. I have in the lease that they are allowed to use $60 of electricity a month anyting over that they have to pay the difference. on the 1st of each month I have it set up where it seems me basically a utility usage for the past month and I bill the renter anyting over the $60 limit. I went in and I set up how much this city is charging her kilowatt hour and what the limit is to reach the $60. During the month at any time I can check to see what percentage of electricity they have left before they reach their 100% or $60 limit. I find that now the renters know that the meter is there and their usage is being monitored that they are being a lot more conservative with the electricity usage. I totally recommend this even for your own home and identify different appliances in your home including the air conditioner heater lights TV anything that uses electricity even the refrigerator. The longer you use it and the more people that use it the smarter it's getting and it really amazes me what technology can do these days. For me this was an extremely Wise choice for others it may not be but if you're trying to lower your electricity consumption in your home or apartment you can use it to figure out what is eating up your electric bill.

Easy install, very informative power graph.

So far so good. Ordered this morning with free same day delivery. Install was a breese - bought a 20A 220 breaker at Home Depot and had it up and running in under 15 minutes. Amazing to watch real-time wattage useage: “Alexa, turn on the pool light” and the graph jumps ~600W, turn off and it drops 500W - it’s a 500W bulb. (See image). Will spend the next few weeks adjusting power and turning things on/off to get a feel for what’s consuming the most. The app says it needs up to 24 hours to calibrate and start to identify things. But so far, just seeing graphs of usage is a great feature. I may update this review after some time passes.

Good. Getting better.

I'm giving it 5 stars because I believe they deserve it. However, getting value from it takes an effort. We've had it for about 3 weeks and it has identified 40% of the load so far. That doesn't mean I can associate all the devices it has discovered with things in our house, yet. I can imagine that what they do is very challenging. I like their idea and am rooting for their success. But it still needs to work well in the real world. They're not completely there yet and they know it and are working hard to improve. Good on them. I bought Smappee last year and was quite disappointed with their reporting, so I got Sense and am quite pleased in comparison. Smappee insists on reporting a "typical" day, month, year and so far I've never been able to look at individual days, hours, etc. for devices. They refuse to disclose how their averages are calculated so you can't unwind their reports mathematically. Sense is wonderful in comparison, reporting load for each hour for each device. I notice that when Sense discovers a new device, its history goes back well beyond the reported discovery. You discover that this new device consumed power a couple weeks ago. The total loads for both matches our utility bills. With both, I sometimes find several real world devices reported under the same label. e.g. One burner on our Stove is reported as the same device as our oven. They both offer an opportunity to merge their devices. Not a good idea, IMO. Even if 2 of their devices can be determined to be part of the same appliance, I would worry that there may be some confusion added by committing to that classification. If the best I can know about "heat 6" is that it is either the oven or the right front burner, I don't want to muddle the situation even more. Sense varies in how long it takes to recognize that a device is running. It takes a while to notice the dishwasher has started, but it sees the garage door instantly. It expect it has to do with the components involved. I expect I can help myself a lot by reorganizing our 2 phase breaker box. We have 2 air conditioners, 2 microwaves, 2 washers, 2 dryers, 2 refrigerators, the stove, and oven. Of course, both air conditioners are on the same side, etc. They both can distinguish between their probes on each side of the box, so I can make sure the air conditioners, etc. are on separate sides of the box. I expect that change will mess up reporting a bit, though. It needs to see devices start and stop, so things that are always on are a problem. Of course we could help by turning our cable box(es) etc. off when not in use. Probably wouldn't be a bad idea anyway.

No exaggeration, just as advertised!

I wanted to get a better grasp on my electrical bill. Being with APS in Arizona I have a on-demand energy from 3pm to 8pm. Things can easily get out of hand. Some of the appliances in the house had no marking on how much energy they would consume and how often(water heater). So I decided to try Sense. Honestly my hopes were not very high as companies always tend to over-do their products in their own ads. However sense has been working like a charm since day 1. It's been less than 2 months and Sense has already recognized all major appliances in the house and a lot of smaller ones. A total of 15! It's super accurate. Apart from letting us plan our energy usage we also use it to check if we forgot the oven on when we leave the house. We use as a notifier if the garage door gets opened and we are not home or are home but are too far from the garage to hear. In conclusion for a 1700+ sq ft. house we keep the AC on(76-78 degrees) almost throughout the whole day, we cook almost everything we eat(so a lot of oven, stove top usage) and our bill cannot exceed $150 a month. Definitely recommending the device.

Love how smart and self-diagnosing this is

Being I am comfortable with wiring (albeit not electrical) and after hearing about the process on reddit, I opted to install Sense myself in our breaker panel. It's very well laid out in the paper instructions you receive in the box and took me about 35 minutes (slow and cautious) to install the first time. I had to fight with the wifi signal, as our breaker box is recessed behind the wall, so I could not place the antenna outside of the box. I didn't think this would be a large issue, but it was. As soon as I put the metal panel back over the breaker, the connection to the Sense monitor instantly dropped. So I ended up sticking the antenna blindly into an egress hole on the left, and now it magically works :p Additionally, I accidentally installed this device on a split 120v, thinking I knew better than Sense (why would it need 240v to power a small device?). Turns out, it's used to measure OTHER devices on the 2 mains. Thankfully, the device alerted me of this 12 hours after install and told me what to do. Impressive! Moving it to a 240 volt resolve the issue, and it began detecting devices! This whole section was me not following instructions, so not deducting a star from the review. Honestly, this technology is amazing, blows my mind and makes me smile when I see a new device it has discovered on my electrical 'network'. There are monthly (usually even bi-monthly) updates to the device, and the company developers are active on their forum. I very much look forward to seeing where all our energy goes, and where we can reduce unnecessary usage.
