Den Großteil dieser Schaltung habe ich mir gespart, weil der
Impulsgenerator von stall.biz
(https://www.stall.biz/project/intelligenter-impulsgeber-w-mit-s0-schnittstelle-zum-nachruesten-fuer-konventionelle-wasserzaehler)
an seiner Ausgangsseite eine ganz ähnliche Schaltung und insbesondere
ebenfalls einen Optokoppler hat.
https://www.stall.biz/wp/wp-content/uploads/2019/03/Folie1.jpg

Der von mir verwendete USB-to-Serial-Adapter hat praktischerweise direkt
einen +5V-Stift, mit dem ich den kompletten Impulsgenerator versorge.
Mit einem 10M-Widerstand (war grad griffbereit) ziehe ich die
RXD-Leitung auf +5V hoch; der S0-Ausgang des Impulsgenerators liegt
zwischen RXD und Masse. Sobald der Optokopper im Impulsgenerator
durchschaltet, geht RXD also auf low.

Mit der auf der Webseite erwähnten vzlogger-Konfiguration scheint auch
irgendwas zu funktioneren, jedenfalls bekomme ich für jedes Abdecken des
Fototransistors eine Reaktion im Log.

Mehr noch nicht, da aktuell keine Middleware da ist.

Das sieht ja schonmal gut aus. Nun also eine Middleware hinstellen.
