Optical pulse counter on IEC 62056-21 port?

My electricity meter has an IEC 62056-21 port, like the round part on http://www.dlms.com/images/ebm108.jpg. This should fit a device like http://www.telink.com.cn/resources/images/600003-01.jpg. But, as I understand it is quite difficult to interface a Flukso with this.

However, the output LED on the meter also flashes red for every Wh, quite bright. I figure it should be much simpler to use the port that way, and connect it to the pulse counter port. That should also be more accurate, as I won't have any problems with bad power factors.

So my question is: how would I hook this up to the Flukso? Can I just tape a photodiode to the meter and hook that up to the Flukso? Or am I overlooking things here?

Perhaps there is a LED pulse reader not too far away. Bart can reveal what his plans are. And, yes a photodiode solution does work with any of the pulse inputs 4 or 5 on the Fluksometer.

We do indeed have first prototypes available that allow you to pick up LED pulses and feed them into the FLM.

Thanks for the replies. Any idea when they will be available in the shop? Then I can decide whether I'll wait, or just get a current clamp for now.
