The gasmeter has been working fine.ThinkPad wrote:The GPIO solution is very nice Conn-artist. I was already looking for something like that.
I am planning to read the pulse LED of my kWh-meter, and also the gasmeter with a reed-contact/IR-sensor which responds to the little mirror in the zero of the counting reel.
I fiddled a bit with a home-made sensor for the watermeter but it only has the tiny rotating serrated wheel and I have not been able to come up with a proper, reliable mechanical solution to read it. Quite frustrating.
