Sense Absorbs $14M to Monitor Appliances, Power Home Automation – Xconomy
The arrival of the truly smart homeâ€”with a legion of Internet-connected appliances and other devices automatically handling tasks while communicating with each other and usâ€”is likely years away.
But Mike Phillips isnâ€™t waiting around. His startup, Sense, sees an opportunity to play a role in enabling home automation by constantly measuring the activity of any machineâ€”smart and â€œdumbâ€ alike.
â€œTo truly meet the promise of the smart home, you have to know everything thatâ€™s going on in the home,â€ says Phillips, Senseâ€™s co-founder and CEO.
Investors agree. Today Cambridge, MA-based Sense announced it raised a little over $14 million in a Series A funding round led by Shell Technology Ventures and Energy Impact Partners, with contributions from earlier backers Capricorn Investment Group, Prelude Ventures, CRV, and hardware-focused venture firm Bolt. Sense has raised just shy of $20 million from investors to date, Phillips says.
The startup and its backers are betting that homeowners will be interested in tracking the performance of devices in the home, much in the same way people monitor health and fitness using wearable technologies like Fitbit.
Senseâ€™s home energy monitoring system consists of sensors that attach to the main breakers inside the homeâ€™s electrical panel and take readings of all the electricity being pumped to various machines throughout the house. The sensor data gets relayed to a small WiFi-connected box also located inside the electrical panel, which crunches information and sends it to the cloud for more analysis.
Senseâ€™s system records one million data points per second. Thatâ€™s more frequent than other smart electricity meters, which typically take measurements every 15 minutes or so, Phillips says. Itâ€™s also a much larger volume of data than some of Senseâ€™s competitors, he adds.
Sense says itâ€™s able to distinguish between the myriad machines running in the homeâ€”dishwashers, ovens, clothes dryers, garage doors, TVs, furnaces, air conditioning units, and so on. It accomplishes this with software algorithms that detect the unique electrical signature of each device.
Sense likens it to listening to devices and recognizing each individual â€œvoice.â€ That comparison is no accident. Phillips and several of the companyâ€™s key team members worked for years on speech recognition technologies. Phillips was founder and chief technology officer at SpeechWorks, which developed speech recognition software for call centers. That company went public, was later sold to ScanSoft, and eventually became Nuance. He went on to start Vlingo, an early creator of voice-enabled virtual assistants for mobile phones, which got acquired by Nuance.
Turns out, much of what Phillips and his colleagues learned in speech recognition translates to energy monitoring. â€œThe fingerprint or the signature of the electrical signals are very similar in a way to the acoustic signatures or acoustic signals that we use in the speech recognition world,â€ Phillips says.
It was difficult to train Senseâ€™s technology to parse out a multitude of electrical signals, which is like â€œ30 people all talking at the same time,â€ Phillips says. That challenge is referred to as the â€œcocktail party problemâ€ in the speech recognition world, and itâ€™s something that industry has yet to solve. But Sense was able to accomplish it in home energy monitoring because power signals are easier for software to understand than human language, Phillips says.
â€œThese things are all on top of each other, but theyâ€™re more distinct,â€ he says. â€œBut just like speech recognition, itâ€™s a big data/machine learning problem. The path to making these things better is more and more data and more and more houses.â€
Thatâ€™s where the new cash should help. â€œNow this is really about scaling upâ€ the business, Phillips says. â€œYouâ€™re going to start to see more of us.â€
The funding will also be used for product development and growing Senseâ€™s team from 18 full-time employees to around 30 by the end of the year, Phillips says.
Phillips declines to share how many devices Sense has sold since it began shipping them last December, but orders of the systemsâ€”currently selling for $249â€”have â€œoutstripped supply by quite a large margin,â€ he says. â€œWith the new funding and our scaling up, we will soon be getting caught up,â€ he adds.
Sense initially positioned the product as a means of boosting energy efficiency, Phillips says. Once homeowners understand how much power each device is using, they can find ways to reduce power consumptionâ€”and thereby lower their electric bills. Perhaps an old air conditioning unit is worn down and siphoning more power than a newer model would, for example.
But Senseâ€™s team soon realized that the applications of home energy monitoring are broader. â€œOnce you can know in detail whatâ€™s happening around the house, think of it as feeding into the smart home,â€ Phillips says. â€œAre the kids home from school yet? Did I leave the oven on? Is the sump pump on when itâ€™s raining?â€
Sense sells directly to consumers, but it plans to more rapidly grow its business in part by also forming partnerships with â€¦ Next Page Â»
