I made my own DIY Wattson EasyFit Y Cable

After taking an original one appart, I tried to make my own DIY Easyfit Y Cable

I went to a supermarket on my way back from work, and found in the HiFi/Video/Computer cables section, this simple audio headphones coupler for 6 EUR

Back home, after diner, I took a pair of pliers and cut the cable in the middle, cut off 1cm of sheaf and split the wires

Connecting the red and white of the left and right (or opposite) together and the grounds together

Connecting the female sides ground cables together

Some solder is applied to the endings


and the wires are all soldered now


and the Y cable is almost ready for a first test


a little insulating tape, and it is plugged into the Wattson Transmitter: Like yesterday with the original Easyfit, it adds up the two CTs current - BTW the two CTs/sensors are inverted here -


Then plugging it into the Transmitter input 1, 2 or 3, it displayed 37.8kW (!!), and I realized something was wrong with my wiring ...



Measuring the jack contacts, I saw that the middle one should not be connected to anything,






So I removed the tape, unsoldered the wires - first time I used my solder sucker/pump, very handy - and identified the color of the middle contact: Red
I then simply cut off all the Red wires, they will not be used at ll, and re-soldered the White ones like before, re-taped,


and re-tested: Fine !
Here all 3 CTs/sensors current, 2 on Y cable, one alone, add up : 3 x 30W = 90W


Here: 2 CTs/sensors connected in Series via the Y cable: Their current readings add up

I then now have a low cost solution to be able to Double the Current Reading on a line, and this is exactly what I need to be able to make Wattson work for USA & Canada Split Phase Electric System.

LEAF Link App Update - Login OK in France !

Following up my last post, I agreed to become a beta tester for the LEAF Link iPhone App in France, along with another user from Ausralia, as we could not get connected
Mike Heasley sent us a new beta version on tuesday, but it did not work for me, as it did for the Australian guy
Finally, last night, he sent me an updated version (1.0.9 with more servers) and this time I could finally get connected :-)
Mike is going to have to send the update to the Apple Store (I think it has to go through the approval procesa gain at Apple) and it should then be available soon ...

Thanks Mike on behalf of the French LEAF drivers !

Yes ! :-)

As my LEAF is sleeping in an underground parking at level - 2, it can not communicate with Nissan servers through its SIM card though  :-( 

So we will see how it works on saturday as we will go to Paris for lunch

Now, it shows a full battery pack :-) (? !)

The next step is to set up the information Feed in my CARWINGS account and in the LEAF 

And I should then be able to send data to the car (routes, contacts, GPS points,etc)

The App is now on the front page of my iPhone :-)

And what is nice is that this App really communicates with you through push notifications and lets you know what is going on; this is a big +

Update 14/09/2012:

And it should probably be OK for all European countries as Mike writes ! Let's hope so




And confirm on MyNissanLEAF (MNL) forum by Mike himself
