OpenEnergyMonitor Java based softwareA couple of java programs, one reads in data from the arduino and prints it to serial, useful for logging to a file and live graphing in kst. There is also a Voltage and Current waveform sampling program that makes it easy to see the shape of the mains AC waveform. Effectively gives you and oscilloscope. |

Dream Home Portal Wish List
I have a CurrentCost Envi 2 CT - 2 wire 100 amp service in USA, IL, Elmhurst using ComEd on Real time pricing for kWh. Elster TOU dumb meter.
I have a BayWeb IP based thermostat for my forced air HVAC system, electric and natural gas.
Current project - house tempurature and electric monitoring with future pulls for weather and electric real time pricing - Arduino Uno - ethershield.
My dream portal would have the current and future 2 day weather:
1.outdoor temp, 2. indoor temps, 3. relative humidity in and 4. outside, 5. wind direction, 6. speed and 7. barometric pressure
It would have current and historical whole house Electric usage as well as heavy load appliance usage - similar to what I already have with CurrentCost web portal.
Now that my electric cost are lower than my natural gas cost, I would like to also monitor the natural gas meter in the same fashion, but current meter is a dumb as a rock sun dial.
Water cost per unit has been rising to over 1 penny per gallon and the city usage some type of RF meter now?
Then the unit would parse data from other web sites and post Real time pricing for electric (kWh energy supply charge) so that immediate decisions can be done.
It coud parse my contractual HVAC web site for its information regarding HVAC run time, energy usage, energy cost in real time pricing and dry contact alerts like my water level high in the sump pump.
Sounds like a tablet PC laptop at this point but that is what we are pretty much at with the Arduino with all its addons. SnapDragon 1GHz, Intel Atom, Intel Sandy Bridge will be the chips on a PCB the size of a mini Arduino stamp costing $30 in todays dollars. Cables and connectors will outcost the main tiny boards.
Would be nice to see
Would be nice to see connectivity/support for google power meter
don't think it is too tricky now all the info/api is out there
I see the pic people have nice support for the embedded Pic to get authenticated onto google power meter
Google have abandoned the
Google have abandoned the power meter project, so there is no longer any point
One idea I'd love to see
One idea I'd love to see implemented (but don't yet know how to do myself...) is a database on a local (or remote) server to collect all the energy data, and a set of scripts which know how to submit that data to www.pachube.com, www.microsoft-hohm.com, www.mapawatt.com, www.wattzon.com, www.google.com/powermeter ... etc.
That way these services could do the heavy lifting of graphing, analysis, comparison etc, and all we'd need to write is the connectors. Just a Simple Matter of Programming, right? :)
Nice idea Eric! yea should
Nice idea Eric! yea should be quite a straight forward thing to implement, It could have a nice easy to use GUI that allowed one to select from a list of services and how often and in what format to send the data for example. I think we need a todo page someware to help develop these ideas, I will create one.
Format of data sent
I am currently in progress of setting up my site to collect data from the Ted5000. I am curious what data outputs does the openenergymonitor have? I was poking around, I am sure it is on the site, but I hadnt found it yet.
Take a look at what I have so far http://myted5k.com/danny and/or http://energymonitorblog.com
On my blog site I am in process of documenting future plans. Right now I am focused on the charts and graphs and just getting the site setup. I have only been active for 2 weeks or so still plenty of progress to be made.
