Installing magnetless speed sensor on dynamo hub

Hi all,
I'm wondering if anyone has already mounted the new speed sensor with the rubber strap on a dynamo hub. The strap is to short to be attached to the hook of the sensor.

Do you see any options to get it properly mounted on a dynamo hub?

Is it possible to mount it somewhere else, i.e. not directly on the hub?

Even if you can mount it on the hub it will likely not work.
The sensor would be affected by the electronics in the dynamo hub.
Can you place it on the other wheel hub instead?

ok, good to know.
Unfortunately the other hub is a NuVinci, which is even bigger. But with the appropriate rubber strap it should work. So now the question is again , where to find the right "tool".

dynamo hub is what.. a power tap in it? what electronics would interfere.. (just lurking and learning here). Read this thread since I never heard of asymetrical hub before, and my ALX320 has what might be an asymetrical hub. wondered if the speed sensor would be an issue on it.

A dynamo is used to provide power to drive lights - lots of magnets and copper whirling around A bit different to a power tap I would guess.

Maybe the GSC-10 is the better option.
