ouch, i need to look in to that, but then it might me true the board is damaged...
(Some other sketches seem to report data to the serial monitor, but i am not sure if the RFM69HW module is working.)

@mfalkvidd
i have the RFM69 HW connected through a 3,3V regulator (including capacitor), so there was never 5V on de Radio board.
iĺl add it to the first post aswell.

Zwollenaar

The code would be as i got it from the site, and its wired like this

Only then for an UNO R3, that would look like:
Wire setup

But with the only differences

it has an 5V to 3,3V regulator and 4.7uF capacitor (instead of directly to 3.3V on the UNO board (wich also doesńt work...))
(3.3V is supplied to the RFM69HW board, i got that checked / measured)
GND between ANA and SCK is also connected to ground.

 * REVISION HISTORY
 * Version 1.0 - Henrik Ekblad
 * Version 1.1 - GizMoCuz
 * 
 * DESCRIPTION
 * Use this sensor to measure volume and flow of your house watermeter.
 * You need to set the correct pulsefactor of your meter (pulses per m3).
 * The sensor starts by fetching current volume reading from gateway (VAR 1).
 * Reports both volume and flow back to gateway.
 *
 * Unfortunately millis() won't increment when the Arduino is in 
 * sleepmode. So we cannot make this sensor sleep if we also want  
 * to calculate/report flow.

Dear all,

i am working to get the Water Pulse meter on Arduino to send the data to Domoticz. (through an RFXtrx322e)

i am rather new to this, but the site looked easy to get this working, but apparently its i bit harder than i thought.
So i am in need of your help.

I use:

Arduino IDE 1.6.7 (linux 64Bit)
Mysensors 1.5 Library
Arduino UNO R3
RFM69HW (rev2) 433MHz (connected through a 3,3V regulator, including 4,7uF capacitor)

i loaded the sketch, and i only get 'radio init fail'

In MyConfig.h i enabled
#define RFM69_FREQUENCY RF69_433MHZ

i am not sure about enabling, cause till now it did'nt matter
//#define MY_SIGNING_FEATURE

In MyTransportRFM69.h i changed: false in to true
bool isRFM69HW=true

What did i miss, or do i need to change/check.

Thanx in advance.
