@mfalkvidd : I think you have to change the condition in if too :
if (batLoop > 1) {
With that, batLoop = 2 when entering in the if (so the 3 values of the array are filled : 0, 1, 2), calculating the average and reseting the batLoop to 0.
If not modify, the array will be set with batArray[3] just before entering the
if (batLoop > 2) {
Other way is to set the batArray size to 4 values, and divide by 4 (I'm actually trying that).
Sorry for not giving news.
So I've done lot of tests, triple check everything and still found "nothing"
I test with deepSleep sketch from lowpowerlab, and still have high current.
I finally receive new rfm69 and change it. And it's ok now !!!
I have 25uA when sleeping !!!
Don't know why, but with new one, it's ok 
Thank you again for your help and your ideas
No no, my intention is just to send the pulse count, every 10 or 15 minutes, with battery powered sensor (and resend the last value even if it not change, due to domoticz not reporting heartbeat, but that is another story )
Hourly and daily value are ok for me.
I was using this sketch as an example just to see how it work and if it could directly do the job.
I enabled sleep_mode.
I was doing that with a testing arduino, directly connected to radio with jumper, and using jumper to simulate reed.
Each time I was doing a pulse that way, the node send the information directly. I was not understanding why. So I run a minimal sketch to try to understand, and I found this thread ...
Finally with all those informations, i think i'll do something like that:
Thank you again for this great help
I've just found it !
I added a 100nf caps between VCC and GND, just near pin 7 and 8, like documented on the MiniCore github page.
https://github.com/MCUdude/MiniCore => DIP-28 package ATmega8/48/88/168/328
And now, it's work as expected. I just plug VCC and GND, and the led blink twice per second.
Don't know why, but it's OK 
Thank you for all your ideas
Thank you so much.
I did not found any schematic for those boards. And the diode and polyfuse are not on the sparkfun design.
The diode let me crazy when trying to verify and trace the signal with multimeter. I take a long time before understanding why my multimeter some times say connected, sometime say not connected. And this night, I tell myself : it's a diode
Thank you again !
@mfalkvidd Thank you.
I've found that too https://www.mysensors.org/apidocs/RFM69_8h_source.html
It's clearly indicated that DIO0 is IRQ.
So I think with "--my-rfm69-irq-pin=" it will do the job.
I'll test it as soon as i'll receive RFM69.
Thank you again
Hello
Here is my last code for my gas meter. If it could help somebody

* The MySensors Arduino library handles the wireless radio link and protocol

* REVISION HISTORY
* Version 1.0 - Henrik Ekblad
* Version 1.1 - GizMoCuz
*
* DESCRIPTION
* Use this sensor to measure volume and flow of your house water meter.
* 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.

I've just found it !
I added a 100nf caps between VCC and GND, just near pin 7 and 8, like documented on the MiniCore github page.
https://github.com/MCUdude/MiniCore => DIP-28 package ATmega8/48/88/168/328
And now, it's work as expected. I just plug VCC and GND, and the led blink twice per second.
Don't know why, but it's OK
Thank you for all your ideas

@skywatch
Yes after flashing MiniCore, the led flash twice per second.That is good!
If I keep only VCC, GND, pullup on Reset and the led on D13, I unplug / replug the power => Nothing, until I force a reset (GND on Reset pin)
How are you removing the power and for how long? Try 30 seconds before reconnect.....
I unplug the vcc dupond cable from breadboard (beetween power source and breadboard). And I plug it again.
Before this message, I unplug during a few seconds. I try 1 minute now, it's the same.
When I force, the led flash twice per second (even without clock, but the fuses are set to 8Mhz Internal)
That is contradictory - it is not 'without clock' if the fuses are set to 8MHx internal - it has 8MHz internal clock running.....OR maybe I mis-understand?
Sorry, I mean without external clock. I remove external Quartz and Caps just after flashing the minicore

Hello
I have 4.8V on the reset pin (directly mesured on the DIL package). I use a 10k pullup resistor.
The atmega was on a single board with uno bootloader before. It was working great, and the reset pin was not connected at all (only vcc/gnd/D2/D4 and clock where connected before I put it on the breadborard)
I've tried with 10k resistor, without resistor (reset floating), with caps. Always the same thing
Hello
I just get a Atmega 328P in DIL package. It was configured with external 16Mhz clock.
I set up it with internal 8mhz and minicore bootloader with Arduino IDE and Arduino as ISP
Here is the configuration I used
Burning the bootloader works well. I follow this guide for wiring, and I add a led on D13 with a 1k resistor to GND.
After burning the bootloader, the led was blinking as usual. I was happy
But, after that, I unplug the arduino as ISP, the clock source, and replug only power source. The led was not blinking anymore. 
I replug the arduino as ISP (not the clock), and use AVRDUDESS to read fuse, and miracle the led restart to blink
Here is the fuses readed
I unplug everything again, and replug only power source ... no blink 
. And I don't know why, I try to send reset (GND to Reset Pin), and blink started.
I've tested it and retested it, the led don't start to blink until I send reset.
Any ideas of why I need to reset to start the arduino ? Is there any fuse or lock that configure it ? Something I miss ?
Thank you for your help
Hello
Have you seen this thread ? Thery talk about G4C .
https://lowpowerlab.com/forum/rf-range-antennas-rfm69-library/designing-a-better-rfm69-radio-module/
Here is other informations about GaAs
https://www.psemi.com/pdf/app_notes/an18.pdf
Not sure to have understood everything
Hello
Where is connected the RST pin of the radio board ? It seems to be connected to pin 9 of arduino.
On the connecting radio page, it's said : "* Adafruit modules need RST connected to GND".
Have you try it ?
You could also try to add RFM69 trace.
#define MY_DEBUG_VERBOSE_RFM69
#define MY_DEBUG_VERBOSE_RFM69_REGISTERS
But I don't know how to read those debug traces...
Editing : I've not seen that it's already activated, sorry
Hope it could help, I'm still mysensors newbie
Thank you so much.
I did not found any schematic for those boards. And the diode and polyfuse are not on the sparkfun design.

Hello
I have some Arduino pro mini Chineese clones which are not exactly made like original. I know it's normal
I m trying to recognize components but i m note sure.
Here is a picture of the part or the card.
I Hope the number i ve added are visible.
So what is
1: no Idea.
2: a diode
3: voltage regulator
4: led indicating power on
5: resistor for the led 4 ?
6: "small" capacitor on vcc ?
7: "Big" capacitor on raw pin ?
8: "Big" capacitor on vcc ?
9: "small" capacitor on rst pin ?
10 : oscillator
Without ?, I'm quite sure. With ? I'm not sure but don't see what else it could be, and no Idea => no Idea 
Thank you for your knowledge
