Sense home energy monitoring


Recommended Posts

Has anyone seen the Sense home energy monitor?  I stumbled across it today while looking up some other stuff on the internet.




I am quite curious about this product and the claims it is making.  By placing a set of current probes on the primary conductor lines that bring power into your home this device is supposed to be able to recognize when devices turn ON/OFF.  It claims to be able to sense common household appliances like washers, dryers and refrigerators.  Here is the full description from the web site.


Every electrical device has a unique electronic signature — its own voice. There is a noisy conversation happening inside your home as every device that’s turned on is talking. All of them. All at once.

The Sense home energy monitor listens to those voices through current sensors on the main breakers in your electric panel. It records them millions of times per second. We then apply multidomain device signature detection algorithms to distinguish one appliance from another — to recognize each individual voice.


Right now this product is in the early launch stage.  It looks like it is pushing data to a cloud and then an iOS app pulls the data down for you to view.  It's not inexpensive at the current price of $199.


I am really curious what it is able to do and what it can tell me (especially about the energy use of my major appliances).  I would definitely like something that can tell my wife how much it costs to run the dryer an extra 20 minutes just to fluff the clothes that were left in over night and got wrinkled.


So...I decided to place an order for one.  It says it may be June before I get this unit but once it arrives I will report back on how it works.

Technology behind this is pretty simple. However, it will be interesting to see/read about how it can determine the difference between like devices. For instance light bulbs that are the same wattage, type, etc.

I got the Sense energy monitor hardware last week and installed it on Friday evening.  It takes a while to "learn" your home and there is no way to speed it up.  Essentially it is trying to look for patterns in the current measurements on the main in the home.  240V devices are easier to detect since they are drawing current from both 120V circuits.  240V devices also tend to draw large amounts of current when they run too.


There is no way for the system to identify a single 100W light bulb in my living room from one in my office.  Banks of lights that are turned on / off as a set will appear as one device to the system.  I even checked and if you use a dimmer on your light switch it will be harder for the system to recognize those lights as a device because the dimmer changes the characteristics that the system is trying to track.


To early to draw any conclusions.  The one thing i like is I can see the daily energy usage in my home and I can see an instantaneous usage like when the dryer is running, the AC is on and the kids have turned on every light in the house.


Downside.  At this time everything is in their APP with no way to store any data offline.

I may have to get one of these if it can work without an app as I am sure they wouldn't have one for windows phone.

Does anyone have sense solar?   Just installed mine and am not convinced the solar side is working as advertised but have nothing to compare it to.

      (I didn't see where you may have started a threat on this..)
      Suggestions for connectivity between your new pool house and main house:
      Simplest would be to go wireless (which I know you do not prefer).  If you end up going this route, I would suggest getting a point-to-point wireless bridge.  Luxul and other companies make these products.  They include a pair of WiFi radios with focused antennas (instead of typical omnidirectional antennas) and outdoor enclosures.  Put an Ethernet switch on each end and treat is as a transparent "wire" between the two locations.
      If you do trench and pull cable, I'm sure you know the "rule of thumb" to always pull at least two of every cable, every when you think you only need one.  If you plan on pulling Ethernet and coax, then at least two of each.  Go for the highest rating (cat 6E ?) and highest quality cables.  Material cost is a one-time thing but the labor and effort is something you want to last many many years and not have to re-do in the future because of an "oops".
      Because a pool house to main house is probably a relatively short run, and is only a single point=to-point connection, I would strongly advise running at least a pair of fiber optic cables also.  With only one run, the fiber cost will be reasonable (versus wiring a large port of a house, etc.) and there is so much versatility.  Even if you don't use it initially, you have the potential to push anything through a fiber - unlimited video, audio, data, etc. and not have to use any compromise solutions like video-over-IP or HDMI/CEC-over-IP, etc.
      For security and IP cameras, books have been written but I would advise considering only cameras that are ONVIF compatible so they can be used with many different front-end apps, applications, or NVR (network video recorder) systems.
      FOR NVR, (to keep everything in-house and not pay monthly cloud or hosting fees), the two programs I have used are Blue Iris (for the PC), and Security Spy (for Mac).  Both of these are awesome with lots of configuration options and many different ways they can be used.  Both of them will give you the "live video multi-camera display in a grid" on your computer that you are looking for.
      Last thoughts - SD definition cameras are still cheaper than 720p or 1080p HD cameras.  If you are going to use a lot of cameras (4 or 8 or more) consider carefully if you really need all of them to be HD.  with SD cameras you will save a lot of money on the cameras, and have less bandwidth (and less storage) to handle their streaming output.
      Finally, I would advise paying a little extra to get cameras with H.264 hardware encoding built-in.  This will reduce the bandwidth over your LAN and allow the NVR software applications to handle more cameras simultaneously as a lot of the initial video processing is offloaded to the camera itself.

      Many of the light switches in my home are connected to 20A circuit breakers, and unfortunately the Z-wave and ZigBee automated switches that I've found are only rated for 15A (if any amperage rating is listed at all).  Does anyone know of a model z-wave or zigbee switch or dimmer that is rated for use on a 20A circuit?
      If there aren't 20A switches available, do electrical codes allow 15A switches on a 20A line if there are only lights controlled by the switch?  My understanding was that a 15A switch could not be used on a 20A line because a short could burn out the switch before tripping the breaker and start a fire.
