Topic: The Open Grid / Power not tracking with main feeds

Sam,

I just noticed a odd thing I never saw in the two mains gadgets. The mains left has a extra box called *streams plugins* this box does not appear in the other mains right??

Also since I alerted you of the discrepencies there appears to be higher power readings showing up on the main left? Did you perform some magic in attempts to investigate this issue for me? Your insight and feed back is appreciated!

OK, so the spinning thing is normal when a new max is received. This is good to know as I have seen this a few times and it does corrolate to a very high load kicking in.

I left some information for Ben at Brultech to give me some insight before I go monkey around with my GEM set up. I would prefer not to lose any data being sent to the SEG site.

As always Sam, I really appreciate your insight and continued support, you rock!

Hey Teken,

Not knowing your setup, and knowing the measurement design is really critical - all I can suggest is to get out pencil and paper take a good look at your board and sensing setup to reverse engineer what's going on.

Then get out your hair dryer and test!

the gauge spun about because you must have hit a new maximum, and it as trying to calculate the new high power relative to this new max.  The new max gets calculated every 15 minutes or so, and your gauge will settle down in time.

Sam,

You're correct and spot on. I did the whole hair dryer thing and something is definately not wired, or programmed right. When I applied the hair dryer to the circuit 28 it appears on the gadget correct. But, it looked like only half of the load was seen on the Main Left?? What was really strange is that both of the meters spun around in complete circles on the SEG??

What would you think would cause such a thing to happen?? I only have a single phase system, and am thinking maybe someone wired the one circuit to the opposite service feed? Would that explain only half of the power being captured on the SEG?

Hey Teken,

This little peculiarity is all about the data you are sending to SEG.  I checked, and made a new dash for you and it seems to me that the Circuit 28 is indeed not reflected in either the main feeds.

Because all these streams are showing the data you are sending (i.e. not calculated streams) then I'd be looking at your measurement installation.  Perhaps some sensors are in backwards, or the voltage taps are on the wrong phase?

One thing I do in these situations is get a good portable load like a hair dryer, kettle or fan heater.  Take this to number 28, fire it up, and see what happens on the main feeds.  If all is fight, you will see the big spike in the circuit 28 and it's corresponding phase feed.

The other thing I found peculiar is one of your main feeds tends negative?  Have you solar power?  If Circuit 28 is on this feed and you have solar, then what you have is a nett situation, and it will not really show on that sensor because your generated solar is not flowing through the sensor, instead into circuit 28.

Happy hunting!  And take your ipad ;)

Topic: The Open Grid / Power not tracking with main feeds

Hello Sam,

I wonder if you could bring some insight and reasons why a gadet would not track properly in one of my main power supplies. If you take a look in my dashboard you will notice that I have 3 primary gadgets that monitor the live power use: 1- Main Left, 2 - Main Right, 28 - Bedroom Plugs.

The 28 - Bedroom Plug is to monitor my daughters laptop which is a huge power hog. When ever the laptop cranks up and uses any power say 200 plus watts. These increases in wattage never reflect in any of the other power meters??

All other devices as soon as they turn on register fine and as far as I can tell are accurate. I have removed the gadget more than once thinking there was some broken association or link. But, it still does not track in either of the main power feeds.

As you're more than aware, accuracy is important in capturing meaningful data. Would you please look into my dash board and see if there is some broken code associated to the 28- Bedroom Plug. As I would very much like to ensure the data presented is truly accurate and sound.

As always I thank you for your continued support and gudiance and supplying us all a place to save our data to.

Topic: The Open Grid / What will happen - ??

Hey Teken,

if the stream is allow negatives, negatives will be there when appropriate.  If not, neg values will be set to zero, for both raw and calculated datas.

Help... that would be nice!  One day a lot of things need to be written...  At least there are the forums.

Sam.

Topic: The Open Grid / What will happen - ??

Sam,

What direct impact will there be by setting the stream to negatives? If I deselect this option will it only change what the value appears to me on the gadget? Or will it actually stop the stream from deducting the incoming power, and subtracting that value from the accumulated daily totals?

I really wish there was a FAQ page explaining all the little features in the SEG site.

Topic: The Open Grid / GEM Not Connecting

If you're connected to the GEM via the GreenEyeSetup on one comm port than the packets will not be sent to the SEG site. You need to either configure another comm port (comm 2) to allow you to do both at the same time. Brultech would be the best place to ask for a step by step process to complete this task.

The site token is the site key . . .

Your packet format should be set to SEG in the systems tab in the GreenEyeSetup. There is a step by step users guide from Brultech please do request a copy and compare.

Win!

Topic: The Open Grid / What will happen - ??

UPDATE: I have changed the stream for the solar array to be set to *green* and also selected *nagatives* in the edit stream. I have also set the GEM to send net power along with changing the polarity of the GEM stream.

The SEG site now displays the solar generation as a positive value. It than subtracts the on the fly incoming power from the main left gadget. It also deducts the daily total, and costs as well!

So with a little tinkering I believe my GEM / SEG combo is set correctly to capture my back fed solar power! I hope this helps someone else down the line.

Topic: The Open Grid / how to delete old data?

Hey Mike,

The upload does not overwrite data.  If you can let me know the streams and data to delete before I can remove the bad data and you can then re-upload your good data.

email me sam at smartenergygroups.com

Topic: The Open Grid / All of my non-raw data graphs are not working

Hey Phil,

Are they looking better now?  There have been some calc work over the last week, that should be over (for now)

Sam, @samotage

Topic: The Open Grid / Kwh Gadgets not rendering data

Hey Teken,

It's likely some recalcs were in progress when this happened.  All should be better now.

Topic: The Open Grid / Kwh Gadgets not rendering data

Hello Sam,

I noticed since the month just rolled over the daily Kwh gadgets don't appear to be working? Daily costs, daily kwh, etc are still all at zero, or have the previous days numbers being displayed.

Topic: The Open Grid / All of my non-raw data graphs are not working

Hi Sam,

All of my non-raw data graphs are not pulling data.  https://smartenergygroups.com/my_things/philsdashboard

I had a outage on my side for a few weeks were i was not uploading data. I fixed some hardware issues and Began uploading data via the API again, including data collected durring those weeks.  I figured that it would take a few day to aggregate all the data.  It has been a week so and looks like it is still having problems.   Any ideas?

thanks 

Phil

Topic: The Open Grid / how to delete old data?

Hi Sam,

I've got a couple of Energy streams that I neglected to configure the 1/3600 calibration on so I have a couple of days of ridiculously high energy consumption on those streams.  I downloaded the raw data for one of those streams, edited the high values down by 1/3600 and then uploaded the data file back to SEG but it didn't seem to have any effect.  Should I have expected this approach to work?

Topic: The Open Grid / SEG is not loading correctly

Hahah!

I did some maths, and your common page was pulling over a million data points.  That's going to cause problems for server, transport and your poor browser!

What I have done is some math on the data rates and adjusting the range based on how fast data is coming.

SEG is kinda designed around 45 seconds, however faster than this is causes "problems" here and there.

Also, nice review.

Sam, 

with the blocky UI ;)

Topic: The Open Grid / SEG is not loading correctly

sam,

sorry to cause grief.  fwiw, i've been using chrome after giving up on opera a couple of months ago.

i've been pushing a lot of bits to a bunch of services to put together a review of sorts:

http://lancet.mit.edu/mwall/projects/power/serv...

just trying to help people sort out the options.  also trying to sort out what needs to be in a self-hosted solution for running on a pi or plug.

these GEM and OWSERVER devices are awesome for data collection!

btw, seg is top of the heap, imho.
