These are the components you would need to build a cable yourself. The relais isn't even necessary to get the SR/F charging. I know that because I made my own version with an ATTiny25 (small arduino-like microcontroller), a small circuitboard and a small 12Vdc power supply. The SR/F just needs the correct pilot PWM signal and doesn't mind if the 230V is already present before it should be. In Europe all normal household outlets are mandatory behind an RCD so it would be redundant and is therefore not included.

In Europe we have the mennekes type 2 connector and that is even bulkier as the J1772. But if you open up the connector you have a lot of air/nothing inside.
Fortunately the second and third phase on the mennekes connector are at the bottom of the connector and are not needed for L1 charging. What I have done is simply cut off the bottom portion of the connector so that phase, neutral, earth, PP and CP pins are still present. this reduces the connector considerably.

Then i designed a 3D printable housing for the remaining part of the connector and used a "pigtail gland" to add a strain relief to the cable.
Now the connector is only 35 mm high and easliy fits under the passenger seat provided that the sillytray is removed

here's another link on how to make a smaller "granny charger"

Wow! That is simply amazing what you have a done and exactly what I thought should be possible. Many thanks to share your work with the community, much appreciated.

Meanwhile I have received a basic EVSE cable I ordered in China which length was cut to my specifications. As I had hoped, it is quite smaller and lighter than those made for cars, or the Zero one. I wish I had all the tools (3d printer) and skills to clone your work but you are getting me nearer to wanting to try it nonetheless. I finally got my SR/F Premium last Friday but without the street number yet so I am not in any kind of hurry for such a project, especially in the winter.

Wonderful, thanks Remmie, I can go ahead with a charge tank knowing I can get/make a cable to fit under the seat with sillytray removed. Thank you so much!

Still on this thread, I have a Zero charge cable for the UK, on a premium SRF.
I was told that pressing the button on the type 2 connector would vary the charge rate 6/8/10A, including making the blue led flash at a different rate.
Mine does nothing, plus I'm getting a constant 21 amp and 2.1 kW indicated. Is this correct?
I know the premium has 2 off 3kW charges and the standard charge cable only uses one in the UK, but isn't it supposed to be nearer 3kW input??

any enlightenment welcome.

I stumbled over this; unfortunately my skills are not of the necessary kind to build it on my own.
It's in German ....

@peterwarm I have the 220V EU version of that wall plug to Type 2 adapter and when I plug it in the wall socket it will do nothing at first. I then have to hit the button closest to the wall socket to enable the circuit and then the blue led will blink 1 or 4 times depending on what mode is currently active (4 options on mine). The other button on the block triggers the breaker switch as a safety test.

To change the level you have to wait for that sequence to finish and then press and hold the smal round button on the type 2charge connector. The blue led will then go out and start blinking, you stop pressing at the desired # of blinks (1-4) to set it to that level.

You can also do this while it's charging in the bike.
