What if any 3rd party services work with GEM?

[scyto]

Are there any 3rd party services apps that support disaggregation with GEM? for example https://plotwatt.com/

Or list of 3rd party apps for example like https://itunes.apple.com/us/app/people- ... 82320?mt=8

Any chance of working with these folks to get GEM support?

The only service we directly integrate with is SmartEnergyGroups.com. We messed around with an Emoncms format, but it didn't work too well when it came to lost packets if I remember correctly.

The script here (by mwall): http://lancet.mit.edu/~mwall/projects/power can do most of them if you want to play around. He also has a good review of all of the services offered, they may have improved a bit since however.

Thanks for the info on Smart Energy Group - I kept wondering what SEG was! I will go read up - looks interesting.

Not sure the script route is for me I am not a programmer and have no desire to learn it (based on my previous forays into scripts).

Can I export data in Green Button format or Google format?

Oh and here is the PlotWatt API https://plotwatt.com/docs/api what's interesting is they claim to be able to detect single appliances on a circuit or on the whole house through dis-aggregation.... seem like a cool thing to be able to apply to GEM data. SEG doesn't seem to do this.

Scyto,

Do you have any idea how they accomplish this task? The reason I ask is that some loads are inconsistent when compared to others. So the *Wattage Signature* would be different each time so their software would have to be very smart to know the differences.

Over all for most homes the power signature is extremely consistent and can be known just at a glance. With the power and capability of the GEM and Dash Box I know exactly what appliance / load is on at any given time.

the concept is nice. in practice i have not seen it work well other than for trivial cases. it is a simple signal processing problem, but the implementations thus far (TED, PlotWatt) are pretty crude. think newton handwriting recognition. i'm sure it will improve, but right now you'll be happier if you just put a ct on each circuit.

one anecdotal data point: when we ran the TED software it could often distinguish between a refrigerator and light bulbs on a single circuit. when we used the MTU to monitor two circuits, each with a refrigeration unit and lights, the TED detection algorithm was useless.

and don't get me started about the user interfaces...

I forget the exact reasoning we didn't implement PlotWatt, at first it was due to each packet needing a timestamp but we have a crude implementation of a RTC with the GEM now (it's mostly accurate from our tests). May have been due to the back and forth to create meters/etc.

Exporting data would have to be on the software-level as the GEM only keeps counters, not individual records. What Google format are you looking at?

Looking at Green button, I'm guessing this would be only for your mains?

thanks, I was Asking about these formats as it is what PlotWatt seems to be able to statically import (i.e. not relatime).

I am hoping given that PlotWatt says it can detect device profiles when just monitoring the main meter, that when combined with something like a GEM it would be able to detect those same appliance profile on each of the channels. Perhaps not? Not sure how their tech work, seems a little magical to me especially when they can detect just from a pulse meter.

Might be able to, depending what's combined on the channel. A refrigerator and furnace for example will usually follow a certain load profile.

Something like a television on the other hand is completely sporadic that if something is combined with one, I can't see being able to sort things out.

There's some examples here: http://www.brultech.com/community/viewt ... p?f=3&t=10

Cool, i will keep investigating, I am actually going to try another PlotWatt (cheap) compatible item to see what PlottWatt can really do and then I will report back.

Once I am a Brultech customer I will submit the formal request to you for PlottWatt support *if* it looks like PlotWatt is useful / they can really do what they claim
