1,7v might be to low. Did you get the correct diode?Well I checked the number on the diode (1n746a) and according to the specs this should be a 3,3v zener..
Go to settings, meters and set the RFXMeter for water to 1000. Thats all
Ok Now I see what I am doing wrong..philchillbill wrote: ↑Monday 20 November 2017 15:20 Your meter produces 1 pulse per liter so measuring 0,134 liters is impossible. The average water consumption per day in the Netherlands is 119 liters per person so 134 sounds dead right to me !

Micha, after failing with the Python script, I got the LUA script working and it works great!Micha123 wrote: ↑Wednesday 06 September 2017 0:13 Im set LUA to DEVICE
Im checking the names again and again. I became that error message.
Maybe i test it with an other browser to start the lua script but i dont think what the problem is....
tested again, script startet, readed the Value from virtual Counter, so i restart the pi and after a simply restart i got the error again.

Thanks again!Go to Setup -> Settings -> Other -> Sensor Timeout and set a value that's long enough for you. I have 4320 which is 72 hours = 3 days.

I'll write a full guide tomorrow if OK for the authors because everything is spread now...
