Hello,
I ordered my openenergymonitor setup a long while ago and never succeeded to understand how to use it and start monitoring my power consumption.
Could someone please help me out ?
These are the data that I succeed to retrieve, What kind of feeds am I supposed to build? I'd like to have Kw in live: http://imgur.com/gNyuPc7
I need to mention that I wrapped my sensors around the red wire only ...
Thank you for your help,
it is going to be much appreciated.

Re: How to start ?
Hello Julien,
Looks like your almost there, the inputs that you see in emontx are as follows:
10:1 is CT1 Power
10:2 is CT2 Power
10:3 is CT3 Power
10:4 is CT4 Power
10:5 is Mains Voltage
10:6 is Temperature
It looks like your CT sensor for CT1 is the wrong way around as its reading negative, you might want to turn that around. Then I would start by adding a 'log to feed' input process for each of the inputs you wish to record. There more on setting this up in the EmonTx v3 quick start guide here http://openenergymonitor.org/emon/modules/emonTxV3
Good work so far!

Hello TrystanLea,
thank you very much for your kind response.
I did read somewhere about the inputs (even though I read that 5 should be temperature ...)
It also took me while to figure out that my Port 2 is not working ...
Anyways, I now have a value that seems legit: 350 with Tv, one light bulb, laptop charging and a small appliance runnig ... Yay!
Now, I'd like to move one step further and send all those nice inputs into a feed in order to be able to collect and visualize them.
I selected Power to kWh -> Create new feed > Main > FIxed interval no avering -> 10 seconds
This is the tricky part to me, I cannot find a valid combination that produces a valid graph, when I go to visualisation, it looks like it's summing up all the values and keeps going up minutes after minutes ... Any idea ?
THank you for your time,
it's really appreciated !
Re: How to start ?
OK,
I finally started to read over every start guide and think I've got something interesting on the track:

This way I have instant kW consumption and also day after day consumption. Am I right ?
Thanks for your time,

Hi Julien,
Using "Power to kWh -> Create new feed > Main > FIxed interval no avering -> 10 seconds" will, as you see, convert the power value to energy used and keep accumulating. You need to log the power before the "Power to kWh" for example
Input 1 = Log to feed "CT1 PowerNow" -> kWh to kwh/d "CT1 EnergyToday" -> Power to kWh "CT1 EnergyTotal" etc
Usually only the values that need scaling eg voltage would have processes before being initially logged eg
Input 5 = x "0.01" -> log to feed "VoltsAC"
