I purchased Sense Home Energy Monitor in December of 2016. It arrived within a week or two of ordering. Installation was simple if you're comfortable working with electrical wiring. I'm handy and don't feel an electrician was needed for the installation as long as you follow the directions (in order).
After the install, the configuration with the app was a snap, and Sense was connected to my WiFi. Immediately I could see the total electrical usage in my house. Individual devices did not immediately show up, and I knew they would not based on the reviews I had read and from the info on Sense's website.
The device has been installed for just under a month now, and I have 11 devices detected. Dryer, interior fridge light, furnace blower, furnace fan, garage opener, microwave, an exterior motion detection light, washer, well pump, water heater, and an unknown heat source.
With a 30-day return policy, I'm a little concerned that this is all I can see at around 20 days. I've written support, but I'm expecting explanations similar to those on their blog.
I'm still hopeful, and I understand that it takes a lot of data to analyze what's happening in my home, I just wish they had a longer return window as it would make me much more comfortable with a new product that so far is living short of its expectations.
At this point, the jury's still out on if the Sense Home Energy Monitor will live up to its promises, but I think I'll stick with it and find out.
Bottom Line: Yes, I would recommend this to a friend
