I am new with the flukso. I have a power meter with a blinking LED. I was wondering whether somebody has already a solution for getting this LED pulse in the flukso. I attache a picture of my power meter.
The best way to find out is to try. I'm assuming that with 2-wire, you mean the cable has two conductors. Not that the sensor uses the 2-wire (I2C) protocol for communication.
If the sensor contains a photo-diode/transistor, then chances are pretty high the interface is configured as an open-collector output. In that case the sensor can indeed be hooked up to either port 4 or 5 of the FLM02.
You could test this out as follows: Attach the sensor to your electricity meter. Connect a multimeter to the sensor output wires. Put the multimeter into resistance measurement. The resistance should be very high when the LED is off and near zero for a short while when the LED is on.

True, my bad. Not 2-wire, 2-core cable it is.

If there is a LED see also http://wiki.volkszaehler.org/hardware/controllers/ir-schreib-lesekopf - it is a German site, but the content should speak for itself... There are a lot of potential options that may be obtained from the variants reading the reflective marker from a gas or water counter using a CNY70 - for reading an LED of course only the photo-transistor part would be needed (and by that "any" phototransistor you might find in your "Grabbelkiste").

Udo's IR-Schreib-Lesekopf is made for reading out German eHz's. It would be interesting to see how we can hook this up to the FLM. It should be possible to hack the FLM's sensor board so that it can work with Udo's Kopf. However, there aren't too many eHz's here in Belgium. So if anyone would be interested doing some live testing/debugging, then we could set up a little integration project.
@larsbern: If you find some time to conduct your tests with the IR photosensor, then please report back on the outcome.

I will order one and try it out. At home I have a Currentcost Optismart which I am not using at the moment. The LED/IR sensor is very nicely done on it but the wiring is a four-contact RJ9. One guy has dismantled the device (http://tickett.wordpress.com/2011/10/26/current-cost-optismart/) and found that green is GND and red is +3V. Then he has done a wiring trick to hook it up with his gas meter. Anyway, the sensor itself could work with Fluksometer but since I am no electrician somebody might have any suggestion what wires you could hook into port 4 or 5?

@Bart: The eHZ-Meter from the description has an communication port that may be (mis?)used via the IR-R/W-head - for all other meters I would guess it is just taking the LED's pulses - for that from Udo's schematics I guess to hook the phototransistor part up to the FLM "just" an open-collector addition should be required; isn't an 74LS07 OC?!, so just hook up an additonal driver and you're done to emulate an S0-pulse output :-) Alternative, use the 3V3 supply by the FLM's port 6 (as described in the manual) and there should be the correct level to put the AND-output directly to the (+) of the 4- or 5-FLM-port (or in the latter case, just use a simple phototransistor to get the LED's pulses from the port 6 (+) to the FLM's 4/5-(+)). I think there are not too many meters that have a highly sophisticated communication option, but a simple LED pulse flasher (but then hopefully also a S0-port itself...) - why easy, when it is possible to do it complicated (old mathematician wisdom)
Best regards, Markus (who's FLM currently has a hiccup, a reset gave no cure and I cannot put it to a hard reset at the moment...) --> to be developped: A cold reset option that can be provided remotely...

Can anyone update this? In particular for Australian meters.

The sensor from the Swedish online store works fine when hooked up to port 4 or 5. It is a bit bulky though. Comes with a velcro template for mounting but no 2 core cable. Sorry for the late response.
Here is a 2-wire solution for a similar (wired) Swedish logger: http://www.energibutiken.se/en/diverse/49-electricity-meter-sensor-for-l...
Could that work for the pulse input on Fluksometer?
