[FHZ] Interfacing S0 (DIN 43864) to FHEM (on Linux/ARM)

Hi,

I finally decided to go for a central measurement of my electricity; as ELV's
EM1000/EMWZ doesn't work for me (no clean glass on power company's meter, IR-
LED can't differenciate between "silver" and "red"), I'll have an Electrician
install a seperate counter in my fuse box, covering all three phases.
I intend to get a Article 125411-62 from Conrad.de (VOLTCRAFT ENERGIEK.-MESSG
3X230V/80A) -- unless I find something cheaper -- which features an S0 interface
(DIN 43864) with 1000 Imp/kWh = 1 Wh/Imp.

Now I'll need something to connect that S0 interface to, I surfed the net to-
day but only came up with rather expensive solutions There exists a rather
cheap 1-Wire module featuring a 2-Port S0 impulse counter[1], but that one's
labelled "out of stock, to be produced on request"; I don't intend to wait
for an unknown time span, I'll need something "on stock".

So, besides cool-but-expensive 4-Port-S0-Eth-Datalogger of busware , do
you know of anything else that can be "just bought" and plugged into a Linux
device (running Linux/ARM => no x86-binary drivers, please ) to interface
with this S0 thingy? (Cat 5 from the meter box to the Linux box is available.)

Interfacing S0 to my Linux box should not be more expensive than, say, 50-60
EUR, as the power meter is already at 130,-- and I want to keep total hard-
ware costs below 200,--.

Thanks,
         kai

Nifty, Danke!

Hmm, Foneras habe ich noch rumfliegen, über Arduino bin ich nun schon
öfter gestolpert ... Mal gucken. Hab' auch 'n 2-S0-UP-Board für unter
30,-- gefunden mittlerweile (1-Wire), das hätte natürlich auch seinen
Charme (noch 'n T/H-1-Wire-Sensor an den Bus und ich hätte 'nen SxxxTH
frei )

Ich hab' nur noch nicht ganz verstanden, wie da nun a) S0 an den Arduino
geklöppelt wird und b) jener mit der Fonera verheiratet ... Aber schon
cool, was heute so alles für "kleines Geld" zu haben ist an Rechenleistung
