Emoncms logging

[kg666]

hoi,

 

i had to reinstall emoncms because it didnt update anymore... (for some wierd reason)

 

but now when i redid the feedlogs, it doesnt work...

i want to + , the gridwattskwd and the loadwattskwd, but it doesnt go good...

 

some one can see the error i did?

seems to be ok for me..but its not..

in example the sum must be : 19.42 + 4.64 

and thats not 4014.64 !!!!

P.S. i did change the log to feed from position 1 - 2 - 3 ,nothing works

kg666,

I'm no EmonCMS expert, but i can see where you are going wrong, but how to fix....

When you say + feed, the last defined feed is GridWatts, hence it does 4010 + 4.64

So I would think to fix, after you do the 19.42 result cals, may try a log to feed (to a new field)?

edit.. 

 

BUT i made a virtual node.. and its working now

 

thanks for your time...

Ok , so new field = virtual node. Still learning this side!!

[kg666]

have a look ;-)

thats how i calculate my system EFF

so i can see if it was efficient that day

P.S. SolarWatts, is just a "free" input , manie doesnt use , so iam happy with that

and you can even put everything in Virtual  so if manie delete the "free" node... you still have the stuff ;-)

 

[kg666]

or not... : 

P.S. Manie dont delete the input  Solarwatts !!! ;-)

Thats the problem with Virtual feeds. At one stage I used almost a 100 of them to do various calculations within Emon. IF you make one mistake within the virtual feeds the whole thing can go belly up (My self has lost at least 2 db's that way). Now I steer clear of them as much as possible. 
Keep in mind that Emon writes the last value received into MySql before it goes into the .dat files. So you could always do the calculations in MySql. I prefer to  do some of the calculations before I send it to Emon and only use it for data logging.

O ja seeing that you have a "spare" field you could also use that multiple times over. 

Just set to Zero and then Add the new input

Manie's ICC ver 2 now logs to Node 0, vs ver 1's Node 1.

That's a bit of bummer , you could change the nodeid in the input table from a 1 to 0 with the following query or 0 to 1

UPDATE`input`SET `nodeid` = replace(`nodeid`, 0, 1 )

and then update the feeds table with 

UPDATE`feeds`SET `tag` = replace(`tag`, "Node 0", "Node 1")

Now if you are not sure what this is first make a backup of the sql table en do at your own risk!!
