Topic: Getting Started / Broken Gadgets?

Yes. I found the problem with the calculated streams, I assumed the minus meant remove the stream, when in fact it means subtract the value. So I have the calculated streams working correctly now.

Did you select "negative numbers are not ok" on the main stream?

Topic: Getting Started / Broken Gadgets?

Currently (not inverted) my watt usage is not displaying the way you've described.

My solar is producing 600 watts.

I am using 50 watts.

The mains are reporting usage of 500 watts.

 

How would I fix this?

 

EDIT: I just tried it with the inverted value. Now I am producing -900 watts, using 200 watts, but my mains reading is 800 watts

 

I switched it back to positive. Created a calculated stream for watts with my Main stream and my Solar stream. It still doesn't seem to be displaying correctly though.

I am producing 200 watts

I am using 50 watts

The calculated stream reads 200 watts

"I guess I need to invert my solar CT in the GEM settings. It's showing positive right now."

Positive is good you don't have to change it

My solar is after the mains, so it's effecting the mains reading.

If you select "negative numbers are not ok" on the main stream, this will than only show electric that you consumed. If your solar is producing more than you're consuming, the main stream would reflect a negative number which would not be used (effectively ignoring a negative numbers for that stream)

So it get the usage reading back I need to do a calculated stream adding all my circuits together then instead of just reading the mains?

So when you say "get the usage reading back" do you mean the actual electric that you needed to purchase? Or do you mean what you actually consumed including solar and utility?

Yeah, that's sorta what i'm looking for. I guess I need to invert my solar CT in the GEM settings. It's showing positive right now. My solar is after the mains, so it's effecting the mains reading. So it get the usage reading back I need to do a calculated stream adding all my circuits together then instead of just reading the mains?

"I am trying to use the monthly and daily charts which tells me to link streams i want to compare, but their stream input says I can only link 1 steam. So how do I add both?"

You would need to use a calculated stream

 

"Also, how would I track power sold back to the power company."

Again you would use a calculated stream, your mains minus solar  

"Will power going out on my mains effect the results of my main CT's?"

Depends on the placement of the CT's, if the solar CT's are closer to the meter then the main CT's then the answer will be no effect. If Solar CT's are after the main CT's, then yes it can effect it. Also depends on how you handle negative numbers.   

 

Not really understanding how to track my solar generation vs my solar usage vs my mains usage vs my solar sold.

Again you would use a calculated stream, your mains minus solar

Take a look at the link below (all tabs) and see what I've done, let me know if any of these are what your'e looking for.

My solar system is up and running now and I want to track how much i'm producing vs how much i'm using.

 

I am trying to use the monthly and daily charts which tells me to link streams i want to compare, but their stream input says I can only link 1 steam. So how do I add both?

Topic: Getting Started / Displaying Kwh

I haven't had a chance to be at home and switch the GEM over to the setup server yet. I work 16 hours a day.

 

I do know that it is running the latest of both firmwares as that was the first thing i did when I installed it. I'm using wifi communication. I can't post on the brultech forum because I cannot access it from work. I'll see if I can find something on the connection timing.

 

thanks.

Topic: Getting Started / Displaying Kwh

I asked you several questions above about what firmware you were on like COM/Engine. Along with what type of connection you're using to connect to the Internet.

I did not see a reply to either questions.

As stated also if you're having issues with the GEM you should really be asking the questions in the Brultech forum where they can see the issue and perhaps offer some advise and suggestions to resolve it.

Often times its a matter of changing the connection timing for the wireless / Ethernet. Other times its just a matter of updating the firmware to resolve previous bugs.

Please create an account on the Brultech forum and pose the question there. This will speed up the resolution process for everyone.

Could someone tell me why my GEM stops sending packets every other day? Every other day at 0900 on the dot the GEM stops sending packets and must be restarted to continue operation. This is very annoying to have to manually restart it.

Topic: Getting Started / Conditional Logic in calculated streams.

As far as I know there is no way to use "if, else, then" logic but Sam can confirm this. The only way that I could see this being done is possibly using a relay that triggers a dry contact that would open and close a lead on the CT for the pump. So when the GEO signals the pump to start the relay would close to complete the connection for the CT. IF the CT on the Geo and pump are the same (40 amp CT) you probably could put them on the same channel. This way when the GEO starts the CT's would combine the numbers for a true picture.

Take a look at Functional Devices RIBU1C

I have two Geothermal units but mine are in a closed loop system so the pump(s) are used only for the GEO's so I just use a calculated stream to combine it for a total.

Topic: Getting Started / Conditional Logic in calculated streams.

Hi,

Yes, both the Geothermal and the well pump are on seperatly monitored brakers..  The well pump is triggered when there is a demand for water. I realise that there will be a very slight discrepency if the GeoThermal is running and there is also a demand for water from another source ( ie, somewone is taking a shower) but that discrepency would be very small.

 

I can identify that the Geothermal is running if there is a draw on that breaker so I'd like to   do something like this:

 

If Geothermal > 0 then

   Calculated strem =  Geothermal + WellPump

else

   Calculated stream = 0

end

Topic: Getting Started / Conditional Logic in calculated streams.

Currently how are you monitoring the two items, are you using CT's off the breaker panel for the well pump? How does the GEO trigger the well pump when it calls for the water flow?

Topic: Getting Started / Conditional Logic in calculated streams.

Hi,

Is there a way to include conditional logic in a calculated stream?

 

I'm running a open loop geothermal that shares the well pump with the house.  I currently have a calculated stream called 'eHeatCooling' that combines the cost of the Geothermal unit and the well pump...  I would like to be able to change the calculated stream to calculate only when the Geothermal is running...

 

IE -  eHeatCooling= Geothermal running? eGeothermal + eWellPump

 

since the WellPump is also being used for household usage, I'm getting 'eHeat' values even though I'm not heating or colling the house.

 

Thanks in advance

 

Luc.

Topic: Brultech / StreamName-2 Issue After Rearranging Temperature Data

Thanks I was able to find and delete the old inactive stream. Then a minute or 2 later it let me change the stream name on the other.

e_ data wasn't being picked up because "Send Current in Packet" wasn't check marked in the GEM setup. As far as increasing it, I am trying to have close to real time monitoring (at least for now) I'll probably increase it later. So unless you can tell me another way to get it, then this is what I need.

 

Edit: Also, the e_ data coming only every 60 seconds(every 4th packet) doesn't matter anyway as wh doesn't need to be real time since they are an accumulation of data, rather than a live display of it.

 

Question: If i were to set it to 60 seconds, will GEM accumulate that 60 seconds worth of data and then send it so that I still have 15 second points on my graph? Or will it only send the data relevant at the time leaving me with a 60 second pointed graph?

I also believe this would resolve the issue that you are seeing, the E_ data coming in every fourth packet.

This also can explain some of the issues when you ran into when running discovery and the E_ data wasn't being picked up.

Your send interval should not be lower than 45 seconds ideally 60 seconds is perfect. Sam indicated sending to SEG at a lower rate would cause rounding issues etc.

How often are you sending data to SEG, every minute?
