Optical pulse counter on IEC 62056-21 port?
by on
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?
