Topic: The Open Grid / What has changed at SEG?

I'm seeing an inconsistency between the statistics bar graph and numerical display that I think is new, and possibly related to the time zone changes discussed above.  Specifically, the bar graph gadget correctly shows the min, max, ave, etc for the current day, but the numerical stats gadget seems to show the previous day's results even though it indicates "for the day ending..." as the current day (same as the bar graph gadget).

I'm not sure if these images work or not.  They are intended to show a snapshot of the two gadgets.

Bar Graph:

Hey Tony,

Yes it was.  

Sam,

with the sun shining in the window.

Sam is this the issue that was fixed a couple of days ago?

Win!

FWIW, none of the data has changed, it's stored in SEG as UTC time, and it's all on the fly time zone mapping, except for daily summaries which are calcualted at the end of your local day in UTC time.

So if you change your time zone, it may be necesary to re-calc.

Sam, @samotage

Looks like it fixed the old data. I have a Locus Energy LGate 101 monitor that was required by the power company. The numbers match better now.

Thank you.

I think it should.  This little thing affected all people who are in a negative hours time zone, now it's being mapped correctly it "should" be ok.

Have a look and report back.

Sam,

I noticed with my solar production the data for the last day of the month would always appear on the first day of the next month. Does this change fix that?

Hey All,

This little change was to fix a time zone issue with the data preparation.  It turned out that those in the US had the incorrect data in the Today and Breakdown gadget.  This would show the previous day when it was set to Today, when it's supposed to show Today.

I will have a look at your problem Teken and investigate, it could be related?

I noticed the change, also. I think it made more sense the old way, but here is a way to please everyone. Add one more tab to the breakdown gadget and make it the same as the usage gadget. A total of seven items with the same labels on both gadgets, i.e. Today, Yesterday, Week, Month, Quarter, Year, Lifetime.

Topic: The Open Grid / What has changed at SEG?

Hello Sam,

Today I noticed that the *Break Down* gadget now shows the current energy readings. In the past, the information was displayed for the previous day.

I am perfectly fine with this display method.

My concern now, is that since this update has taken place I have noticed the line graphps no longer display the green generated power accurately in the heat maps. 

ie. Negative or generated power would show below the zero mark. Now all power seems to appear in the positive line graph, regardless of consumed  vs generated?

I am sorry if this is unclear I will try to post up an image to illustrate my problem.

Teken . . .

Thanks for fixing the units.  ;)  And for fixing the bug!

Hey Eric,

I had another look, and found a small time zone problem, and fixed it.  The days should add up.  Also, I fixed up your units so they match :D

Should be good to go!

Thanks for reporting the anomaly, it's appreciated.   It worked just fine for Australian time, though your CST seems to have had a previously undetected fault.

Sam, @samotage

Hm ok I will double check the units.

What about one widget showing 22.8kWh today, and the other widget saying that was yesterday's usage?

Thanks,

-Eric

Hey Eric,

You need to set your streams to the same prefix, this is a feature not a fault :D

If they are both kWh then all will add correctly.

Topic: Comments and Suggestions / Bugs in "The Breakdown?"

I have 2 widgets on a dashboard; "The Breakdown" and "Today"

"Today" shows 7.72kWh today, and 22.8kWh yesterday for my "Mains" stream.

"The Breakdown" is showing 22.8kWh for today (on the "Day") tab, and it's adding "112 Wh" on one channel with "22.8 kWh" on the other channel (note the different units) and getting a total of 134 kWh  (?!)

 

I don't use 134 kWh in a day.  ;)

Any ideas?

Thanks,

-Eric

Topic: Getting Started / Getting Started Blog Post?

Getting Started Draft:

0. Determine your goals, plan out your system. How many circuits do you want to monitor?  Determine where it will physically be mounted. Think about proximity to the electical panel (sensor leads are about a meter long), also think about AC outlet to power the box and how to mount on wall. Perhaps other data connections like hard-wired link you your network or a computer, also other sensors like one-wire temp sensors

0.3 order the right hardware 

0.5 Wait patiently for a nice box to show up from Australia :)

1. Unbox contents

2. If you bought a SEGMeter SEGBox, sensors, enclosure or any other bits, ensure they are what you bought. (Sam, may be nice to include a bill of materials and receipt in the box, just a suggestion. Shops like Adafruit and sparkfun do a good job here)

3. In my case I have a SEGMeter v2.5, a SEGBox v2 and 8 sensors, 4 5mm and 4 13mm.

3.5 The SEGMeter and SEGBox come preconfigured with the right software, all you have to do is get them physically set up, boot them up and get them on your LAN. They will phone home and connect to the backend later in the process. 

4. Ensure 6-wire cable between SEGBox and SEGMeter are connected tightly (white on left, red on right in my case)

5. find a normal ethernet patch cable, not crossover cable. plug in patch cable from SEGBox to a computer with an ethernet port.

6. Plug in AC adaptor to wall and connect to SEGBox

7. Follow steps from here to connect to OpenWRT on SEGBox: http://smartenergygroups.com/forums/11-SEGmeter/topics/27-Configure-SEGbox-WiFi-

8. Discovery! once the SEGBox is on your wifi network and can get out to the internet you can initial Site Discovery by going to this URL http://smartenergygroups.com/sites and giving your site a name.

8.The backend system will talk with your SEGBox and Meter and query things like number of sensors.

9. You can now unplug the ethernet line connecting your SEGBox to your local machine. (Sam, What is the process if you want to hardwire your SEGBox to your lan via Ethernet? also how to connect to the arduino board via serial over usb or FDDI?)

10. Set up some sensors, either 13mm or 5 mm. Note: Ensure you power off your SEG before adding, removing or reconfiguring sensors. (Sam, any more detail here?)

11. Standard caveats about working around live line voltage. If you do not know what your are doing, call an electriction before opening your electical panel and attempting to do anything around live wires. Even if you do know what you are doing, please think twice whenever working in the box!

12 Familiarize yourself with your hardware - review what is happening on the SEGMeter and SEGBox. (it would be nice to have a diagram showing what components do what here, especially comparing to a standard arduino board for example, comparing a SEG to an Uno for operations like reset, connecting to a computer, uploading sketches, etc. ) Read the forums and blog posts to find some of this information.

Aha, I knew I saw this previously!

SEGMeter: https://github.com/samotage/Aiko/tree/master/SEGmeter

SEGBox: https://github.com/samotage/Aiko/tree/master/SEGbox 

 

Would bo good to have a link from the main SEG website somewhere.

Topic: Getting Started / Open Source Code Location Online?

While my SEGMeter boots up and i connect for the first time, I presume the various components (the SEGBox code using OpenWRT and the SEGMeter arduino sketches) use an open source license? Are they available online posted on a site like github?

I presume the backend website and database code is closed source, right?
